Enter the Fifth Ninja

It had been a week since the battle against the Kraang and the Hamato teens still had not found any clues about their whereabouts or what had become of Kirby. April had been helping out as best she could, but there was only so much she could really do. Leo had to continue to act as leader because Yoshi still had not fully recovered from the injury he received from Snakeweed; he could walk better, but he still could not fight like he normally did. It was pretty rough on Donnie as well; ever since the Kraang's attempt at abducting him, his siblings had not allowed him to go with them on missions to look for the Kraang out fear of the Kraang attempting to kidnap again; Yoshi did not even let him go out without at least one of his siblings with him. While Donnie understood why they worried so much, he wished that they would not leave him out.

At the moment, Donnie was waiting at home for his siblings to return from their mission. Earlier that day, April had told him about a lab that she was sure that the Kraang would break into. Donnie had wanted to go with them, naturally, but his siblings said he could not out fear that the Kraang might recognize him and try to take him. Donnie tried arguing with them, but found he could not convince them to let him go.

Shen had just finished closing the antique shop and headed up to the upper level to join her son. Upon arrival, Shen noticed that he looked upset about something.

"What is the matter, Donatello?" she asked.

To answer her question, Donnie sighed and said, "I feel like I'm useless."

"What?" Shen asked, surprised at what her son just said. "Useless? Why would you think such a thing?"

"I guess it has a lot to do with the fact that the others keep leaving me out of missions," said Donnie. "I mean, I'm just as skilled a fighter as them."

Shen simply put a hand on his shoulder and told him, "Donatello, you know they didn't leave behind because they think you are weak. They just want to protect you because they love you and don't want to lose you."

"I know," said Donnie, "But still can't help but feel like I could be doing more. The problem is Leo, Miwa, Raph, Mikey, and even dad don't wanna let me."

Shen could tell her was feeling really bad about the whole situation, so she suggested to Donnie, "If you really feel strongly about this, why don't you talk to your father and siblings about it. I'm sure if you talk to them they will come around."

Donnie thought about the idea for a bit and then answered, "Maybe you're right."

Shen smiled and said, "That's the spirit. Now, come along to the lair; I believe your father and siblings are all there together by now."

"Cool," said Donnie, standing up from the couch, "That means I can talk to all of them at once. Hopefully they'll listen to me."

The two got ready to leave and Shen Donnie in an assuring voice, "I'm sure they will."

Together, Shen and Donnie left the shop through the back door and made their way down a manhole to the sewers. As the two walked through the tunnel, Donnie thought about what he wanted to say to them to get them to understand how he feels. They were just getting close to the entrance to the lair when they heard the sound of Yoshi yelling angrily.

"What's going on?" Donnie asked.

"I'm not sure," said Shen.

Curious as to what could have been the cause of Yoshi's angry yell, Shen and Donnie quickened their pace. Once they got past the turnstiles, Shen and Donnie saw Yoshi standing in front of Leo, Raph, Miwa, and Mikey looking sternly at them.

"Yoshi?" Shen called, getting her husband and children's attention, "What is going on?"

In response, Yoshi sighed and said, "Raphael let his anger get the best of him again."

Shen shook her head in disappointment at the news, while Donnie turned to his older brother and asked, "What did you do now?"

"Nothing!" Raph hissed.

Miwa looked over at Donnie and told him, "An old bald guy came onto the roof we were spying from and started yelling and insulting us, so Raph, in his infinite wisdom, decided to yell back. When he did that, the Kraang heard his shouting match and found us."

Donnie smacked his forehead and said, "Oh god, Raph! You blew their cover?"

Raph was about to retort when Yoshi stepped and said, "Not only that, but your siblings were caught... on video!"

"What!?" Donnie and Shen asked in shock.

Leo looked annoyed as he explained, "Yeah, that guy Raph was fighting recorded our fight with the Kraang on his phone. And now he might just sell it to someone or post it on the internet for the whole world to see. And it's all thanks to Raph."

"Shut it, Leo!" Raph snapped at his older brother, and then he turned to his father and said, "Dad, this guy was the angriest, nastiest guy you ever met."

"Except for you, that is," said Mikey.

Raph ignored what Mikey said and continued saying to his father, "You should've heard the insults this guy was throwing at us. They were so... insulting!"

"Oh, I did not realize he said mean things," said Yoshi, in a sarcastic tone, "Of course, you had no choice but to... jeopardize your mission!"

Raph slumped at his father's words, and then Mikey grinned at him and said, "Burn."

"Michelangelo," Shen scolded her youngest child.

"You are ninjas. You work in the shadows. In secret," Yoshi explained to his children, "This becomes difficult if there is proof of your ninja existence in high definition!"

"On the bright side, at least if it gets posted online no one will know it's us in that video," said Mikey.

"What if someone does recognize us, Mikey?" Miwa asked, "They could reveal our true identities to the whole world. We can't take that risk."

"Dad, we know where this guy lives," Raph explained, "All we need to do is find and then shake him until the tape pops out."

"There's no tape, Raph," said Donnie, getting Raph's attention, "Video phones use flash memory-"

Before Donnie could say more, Raph glared at him and said, "It's an expression."

"Not a very good one," said Donnie.

"Hey!" Raph snapped, "Don't give me a lip, brainiac!"

"Raphael!" Yoshi shouted to get his second son's attention. And then he composed himself and said, "Anger is self-destructive."

"I always thought it was others-destructive," said Raph.

"Raphael!" Yoshi snapped, "Stand up."

Raph complied, looking defeated. Mikey teased his brother for being in trouble, only to earn a glared from said brother. Yoshi ordered his children into the dojo he had set up in the lair, saying that Raphael needed to learn his lesson. Donnie had wanted to talk his family, but he figured it might have to wait until after Raph was punished.

In the dojo, Yoshi had Raph dodge suction cup arrows that his brothers and sister would fire at him. He dodged them all with ease and even took a bow afterwards. Unfortunately for Raph, his lesson was not over.

"Again!" said Yoshi, "Only this time, Miwa, Leonardo, Donatello, and Michelangelo, insult Raphael."

Donnie's eyes widened as he asked, "Wait, you want us to insult him?"

"Yes," said Yoshi.

"And he can't fight back?" Donnie asked.

"No," said Yoshi.

Donnie smiled and said, "I'm feeling pretty good about this plan."

"You're not the only one, little brother," said Miwa, readying her bow, "I'm gonna have so much fun with this."

"Hajime!" said Yoshi, telling them to start.

The four circled Raph, bows at the ready, while Raph prepared to dodge their arrows. He thought he was prepared for anything, but he would quickly be proven wrong.

Mikey laughed and said, "You move like a bloated buffalo!" And then he released his arrow.

Raph dodged Mikey's arrow, and then glared at him and snapped, "I do not!"

"And you're always whining," said Leo, preparing his bow, "Poor me. Nobody understands me."

"Well, you don't understand me!" said Raph, who got hit in the back by Leo's arrow. The others laughed at his expense while Miwa decided to take her turn.

"And you can never take criticism," she said, "Even when it's meant to be constructive."

"That's not true!" Raph snapped. Right after he said that, Miwa's arrow hit him square in the face.

Next was Donnie's turn. He was having a little trouble at first, and then he got his bow ready and said, "And you don't keep your back straight when doing omote-gote-gyaku!" he released his arrow and it got stuck to Raph's back, and then he released another arrow and added, "And you're ugly!"

Donnie laughed at the last insult. The four continued to insult and taunt Raph while shooting arrows at him until he fell to the floor. Once they were finished, Raph looked a lot like a porcupine.

Mikey sighed happily and said, "I wish this moment could last forever."

"You know what, forget this!" Raph yelled, "This is stupid!"

Raph got up and walked towards their father while Mikey whined, "Aw! It didn't!"

Raph looked up at his Yoshi, who explained to him, "Minicusasion is the ability to endure insults with patients and humility. You cannot be a true ninja until you master it."

Mikey laughed a little when two arrows fell off of Raph's head, and Raph got ready to punch him until Yoshi asked, "Understood?"

"Hai, father," said Raph.

Yoshi then turned his attention to all of his children and said, "You must get that video back." he turned his attention particularly Raph as he added, "Using reason, not force."

"Okay," said Donnie, "I'll go get my gear."

He was about to gear up when Raph stopped him and said, "Whoa, whoa, whoa. You're not coming with us."

Donnie rolled his eyes and said, "We're just going to get a video back from a jerk. It's not like the Kraang will be there waiting for us."

"What if they do show up and recognize you?" Leo asked, "We can't risk that."

"It'll be fine, Leo," said Donnie, "Between the mask and the rest of the outfit, there's no way they will recognize me if they show up."

Leo looked Donnie right in the eyes and said, "It's too dangerous. They almost took you away before; I don't want that to happen again."

"It won't," said Donnie, "Please, let me go with you. I can help."

Miwa walked up to her brother and said, "You're right, it won't happen, because you're staying home where it's safe."

Donnie sighed and said, "Guys, I understand that you wanna protect me, but forcing me to stay home isn't really doing me any favors. To be honest, I've been feeling kinda left out."

The family stayed silent for a moment. And then Yoshi put a hand on his third son's shoulder and told him, "I am sorry, Donatello. I know you don't like being left out. But I also know that the Kraang may still be after you. And if they are, they may stop at nothing to find you. I'm afraid home, school, and the lair are the only safe places for you for now."

"But, dad-" Donnie began.

"I am sorry, my son, that is my final word," said Yoshi.

Before Donnie could reply, his father and siblings left the dojo. Donnie stood where he was, frozen like a statue in shock.

Shen put a hand on Donnie's shoulder and told him, "Come along, Donatello. Let's go home. We'll try to talk to them again tomorrow."

"You go ahead, mom," said Donnie, "I'd like to stay here a little bit longer."

"Okay," said Shen, removing her hand from her son's shoulder, "But don't stay too late."

"Okay," said Donnie.

With that, Shen left the dojo to return home with Yoshi. After she was gone, Donnie grabbed his collapsible bo staff to hide in his back pocket and left the dojo. He then made his way out of the lair and through the tunnels back up to the surface. He walked over to his bike, unlocked the chain and got on to ride.

Before leaving, Donnie looked at the shop and said, "Forgive me, my family." And with that, Donnie road through the streets to find the man who recorded his siblings; he remembered the address of the lab and was sure he could find a faster way there and could easily find the man. Since this was not a ninja mission, per-say, he felt that his casual look would be enough.

Upon arriving at the lab April told him about, Donnie found an apartment building across the street. He was about to go looking around for the man that tapped his siblings when he heard a man's voice coming out of the building.

"I swear on my mother's grave, these kids were crazy!" said a man who fit the description his sister gave him earlier, "They were dressed in black and they knew Kung Fu! They were fighting these guys with laser guns like they were some kind of super heroes! You can't tell me that's not worth something!"

Donnie rolled his eyes at the 'Kung Fu' statement, then got off his bike and walked over to the man. He tapped the man's shoulder and got his attention.

"I'll call you back," the man said to his contact. He then hung up the phone and said, "Whadya you want, four-eyes?"

Donnie's eye twitched a little as he thought to himself 'I see Raph wasn't exaggerating about this guy.' But never the less, Donnie kept his composure and talked peacefully with the man.

Donnie laughed nervously and said, "This is really embarrassing, but I believe you recorded some people on your roof earlier this evening."

"Maybe I did, and maybe I didn't," the man rudely said to Donnie, "What's it to you?"

"Well, the thing is, they were friends of mine and they were shooting a scene for a movie that we're entering in a film contest," Donnie lied, "It's an action about a secret ninja alliance saving the world from alien invaders."

Donnie hoped that the man would buy that. Unfortunately, the man looked unconvinced.

"You think I'm stupid or something?" he asked, "If your friends were shooting a movie scene, how come I didn't see any cameras? And those were definitely real lasers that almost killed me."

Donnie mentally cursed himself for not coming up with a better story. He then started wracking his brain for another story, but could think of nothing that the man would believe. Finally, he realized that he had no choice but to tell the truth, but be vague so as to not reveal too much.

"Okay, I'm gonna level with you here," he began, "When you recorded my friends fight earlier with your phone, you put their safety at risk. I just want that video deleted so that they're not at risk of being recognized on the internet by people they know. So, you think you could do that for me?"

The man seemed to be contemplating the idea. Donnie waited patiently for his answer, finally, the man said, "What's in it for me?"

Donnie looked surprised and asked, "Excuse me?"

"Well, I figure I've got you over a barrel so you've got to make it worth my while," said the man.

'You've gotta be kidding me,' Donnie thought to himself. He sighed in annoyance and said, "Okay, what do you want?"

The man thought for a second and then said, "A couple thousand bucks oughta cover it."

'Seriously? Do I look like I have that kind of money?'Donnie thought to himself. He was about to say something back, when he heard a voice yell, "Are you seriously trying to extort money from him?!"

Donnie turned around and froze at the sight of his siblings, and Raph looked angry. Raph stormed over to Donnie and the man, ignoring his siblings pleads to calm down.

Donnie walked up to Raph and said, "I can explain."

Raph shoved Donnie out of the way and said, "I'll deal with you later." And then he walked over to the man and yelled, "I wasn't gonna hurt you at first, but now I think I've changed my mind."

Raph grabbed the man and threw him to the ground. He then stood over him with his fist raised and yelled, "You had better give me that phone, or so help me, I'll kick your hairy butt all the way to New Jersey!"

"Guys, I've got this," said Donnie, attempting to make peace.

Miwa got in Donnie's face and snapped, "You were not supposed to be here!"

Mikey got in between his brother and sister and said, "Hey, lay off him. He was just trying to help."

While the others were fighting with each other, Leo spotted something and yelled, "Guys, the Kraang!"

Everyone looked ahead and saw the Kraang's van driving straight towards them with the headlights on. Miwa tackled Donnie and Mikey out of the way, but Raph and the man were frozen. Leo saw this and pushed them out of the way just in time to avoid the van. After the van left, the teens saw a truck driving their way with Kraang inside.

"Let's not let them get away," said Miwa.

"Couldn't have said it better myself," said Leo.

"Agreed," said Raph, and then he picked up an oil drum and threw it at the truck. The result was that the driver lost control of the vehicle and crashed into a wall.

Raph smiled proudly at his work and crossed his arms over his chest as he said, "Well, that was easy."

Leo, Miwa, and Mikey looked to examine Raph handy work, while Donnie crawled on the ground as if trying to find something. Mikey noticed this and asked, "What'cha doing done there, D?"

"I lost my glasses when we had to dive to avoid that van," said Donnie, "Can one of you give me a hand? I can't see very well."

"Sure thing," said Mikey. He looked on the ground until he finally found his brother's missing eye wear. "Oh, found 'em."

"Thanks," said Donnie, taking his glasses back and putting them on. His eyes widened in shock when he saw the back of the truck open and three Kraang come out armed with lasers.

"I think you spoke too soon when you said that was easy, Red!" Donnie screamed as he dodged laser fire.

The others followed suit and scrambled in different directions. They then got their weapons ready and charged into battle. Donnie tried to join them, but Leo told him to hang back.

During the fight, Donnie, saw the man trying to sneak away with his phone, which had the video in it. Seeing this as a chance to prove himself, Donnie attempted to sneak past the fighting and get to the man. Unfortunately, the man got knocked into the back of the truck, which meant Donnie would have to climb in after him to get the phone. Unfortunately, a Kraang saw him and grabbed him.

"The one known as Donatello Kurama will come with Kraang to the place that Kraang will take him," said the Kraang, "Kraang has use of the one known as Donatello Kurama."

"I'm not going anywhere with you guys!" Donnie snapped, and then hit the Kraang with his staff, forcing it to release him.

He tried to run after the man with the phone, but another Kraang stopped him and said, "Kraang was not asking, Kraang was telling."

While Donnie was trying to fight off the Kraang, Raph stormed over to the truck and left Leo to fight a Kraang by himself. Raph climbed inside the van, got in the man's face and said, in the threatening voice, "You give me that phone right now!"

The man backed away in fear and held his phone protectively. He then looked past Raph as if seeing something. Raph turned around at the sound of shouting and saw three Kraang climb in, one of whom was holding Donnie tightly by his arm and pulling him inside. The other two Kraang that were left got into the front of the truck, started, and drove away as fast as they could, leaving the three remaining ninjas to watch them in surprise. That is until Leo pointed out something important to Miwa and Mikey.

"Guys, Kurogane and Donatello are in the truck!" he said, and they all ran as fast as they could to catch up.

Inside the truck, Raph and Donnie were fighting the Kraang as the bald man sat and watched them. Once Raph had defeated enough of them, he decided that it would be a good time to escape.

Raph turned to the man, held out his hand, and said, "Let's get of here!"

The man simply glared at him and said, "Forget it! I'm sick of you brats! In fact, I might just sell my video of you to these guys."

Donnie glared and yelled, "Really?! These guys could kill you before they even consider giving you anything!" Right after Donnie yelled that, he and Raph heard Mikey call out to them.

"You guys!" he called. Raph and Donnie looked out of the truck and saw Leo, Miwa, and Mikey chasing the truck and Mikey yelled again, "Get out of there!"

"I'll just be a sec!" said Raph, and then he picked Donnie up and yelled, "Catch!"

"Wait! Wait! Think about this for a minute!" Donnie started saying, but Raph ignored Donnie and threw him out of the truck.

Donnie screamed and shut his eyes as he waited for impact. Luckily, Leo stood his ground and caught him just in time. Raph, meanwhile, turned his attention back to the man with the video phone.

"Listen, jerk face," Raph yelled, grabbing him by the arm, "We are not brats and these guys are bad news! I may not like you, but that doesn't mean I want you dead!"

"How do I know you're not just making that stuff up?" the man asked.

Raph was about respond when a Kraang grabbed him from behind and dragged him towards the still open back of the truck. They then threw him out and he rolled right into Miwa and Mikey, causing them all to tumble and fall. As the truck drove away, the teens could have sworn they heard the man with the video phone taunting them.

After Leo and Donnie caught up to them, Miwa, Mikey, and Raph got up and dusted themselves off. Mickey told Leo that the Kraang escaped with the man with the video phone, and Leo glared at Raph.

"Nice going, Raph," said Leo.

"What did I do?" Raph asked, not understanding how what happened was his fault.

"What did you do?" Leo said, flabbergasted, "You left the rest in the middle of the fight to yell at somebody! We could've stopped them, but thanks to your temper, the guy with the tape..."

Donnie raised a finger and corrected Leo, "Again, flash memory..."

Leo glared at Donnie and said, "Not now!" he then turned back to Raph and said, "... is in the hands of the Kraang! How are we supposed to find them?"

While Leo scolded Raph, Donnie noticed something on the ground. Upon closer inspection, he found that it was fluid from the truck. He looked ahead and saw a trail of fluid leading in the same direction the truck drove away.

"Guys, the truck's leaking," said Donnie.

This news made Miwa smile and say, "Great. We can follow it to their hideout."

"And then we bash some bots," said Raph. He then noticed his siblings giving him weird looks, "What?"

"We are going to bash some bots," said Leo, "You are taking Donnie home and waiting for us there."

"What?" both Donnie and Raph said.

Leo sighed and explained, "Raph, you need to control your temper. Until then, We just can't trust you." He then turned to Donnie and said, "And, Donnie, you weren't even supposed to be here in the first place."

"You've gotta be kidding me," said Raph. He then turned to his youngest brother and older sister and asked, "Miwa, Mikey, are we really gonna let Leo power trip us like this?"

"I think he's right, Raph. Sorry," said Miwa, then she looked to Donnie and added, "About both of you."

Donnie stepped forward and said, "I'm sorry that this happened. It won't happen again. Please, just let me help."

"Donnie, the Kraang almost took you again," said Miwa, "Don't you see? This incident only proves that it's too dangerous for you."

"Not any more than it is for you!" Donnie snapped, "They only try to kidnap me, they actually try to kill you!"

Leo and Miwa looked sternly at their brother and Leo said, "We'll talk about this later."

Miwa, Leo, and Mikey turned to follow the trail to the Kraang's hideout. Before leaving, Mikey turned back to his other two brothers and said, "Sorry, guys."

As Miwa, Leo, and Mikey walked away into the night, Donnie watched them and felt sad, and Raph growled in anger and threw his sais to the ground. After that, he picked them up and started to walk back home with Donnie following close behind, stopping only to collect his bike.

Upon their arrival home, Raph went straight to his and Leo's shared bedroom and plopped down onto his bed, while Donnie was scolded by their parents for sneaking away to join his siblings on the mission.

While he was in his room, Raph started ranting about what happened that night to his pet turtle, Spike.

"So what if I have a temper? I'm still the best fighter we've got. In fact, If anything, my anger makes me a better fighter. You understand me, right?" Raph said to his pet. He then sat up and said to Spike, "Chew on your leaf if you understand me."

Upon command, Spike took a bite out of the lettuce leaf that Raph had given him earlier. Raph smiled as he watched his pet chew and said, "I thought so."

"I understand you too," said a familiar voice. Raph jumped at the sound and looked up to see Yoshi standing in the doorway.

Raph calmed down and said, "Seriously, you've gotta knock or something."

Yoshi sat down next to Raph and said, "Raphael, let me tell you a story."

"Dad, I'm not in the mood for a story," said Raph.

Yoshi turned to the turtle and said, "Spike, chew on your leaf if you are in the mood for a story." on command, Spike took a bite out of the leaf and chewed it. Yoshi then turned back to his second son and said, "Very well. When I was a young man, I fell in love with a woman..."

"Oh, look at the time. Is it that late? I better get ready for bed," said Raph, trying to excuse himself from the story.

"Nice try, Raphael. You and I both know that tomorrow is Sunday," said Yoshi, forcing Raph to pay attention to the story. He then cleared his throat and continued, "Her name was Tang Shen, your mother. But I was not the only man who loved her, there was another man competing for her attention, Oroku Saki."

"The Shredder," Raph hissed, recalling everything he had heard about his biological father.

Yoshi nodded his head and continued the story, "One day, he insulted me in front of her. He called me many things. I felt I could not let those insults go unanswered, so I attacked him. He left home that very day and over time our rivalry festered into hatred, until one day he sought to finish me. And you know the rest. I lost my temper and my father paid the price with his life."

By the end of the story, Yoshi's face was filled with guilt and Raph's was filled with shock.

Raph put his hand on his father's shoulder and said, "Dad, it wasn't your fault. Shredder insulted you, you didn't have a choice. Plus, it sounds like he was never right in the head to begin with."

Yoshi looked at his son and said, "You may be right about his lack of sanity, but that does not change the fact that I was the one who made his words into weapons. I could have chosen to ignore his insults and let his words wash over me, like a river over stone, but instead, I let him anger me." He looked Raph right in the eye and said, "That's the choice I made. What choice will you make?"

With that, Yoshi stood up and left the room, leaving Raph think about what his father had told him.

In the living room, Donnie was working on his computer and thinking about what happened earlier. He suddenly felt a hand touch his shoulder and looked up to see his mother.

"I'm sorry I lied, mom," said Donnie, "But I just couldn't stand by and do nothing while my family's safety was at stake."

"I know," said Shen, "You're father always said you had my spirit. I was never one to stand by and do nothing either; especially when those I love were involved."

Donnie smiled at his mother's words and said, "Thanks."

"However, I do not approve of you knowingly putting yourself in danger just to prove yourself," said Shen.

"The others do the same to protect the city," said Donnie, "I wanna to help them do that. I wanna be a part of the team. To be honest, I've been feeling smothered, uncomfortable, helpless and... I haven't even had a say in anything. It's like I don't even matter."

"I can't believe we never realized that before," said a familiar voice. Shen and Donnie turned around and saw Raph and Yoshi. Raph was the one who spoke first, "We just wanted to keep you safe, we didn't realize we were hurting you. Sorry man."

"I'm a little surprised myself," said Yoshi, "I'm master ninja as well as your father and even I did not realize that we made you feel this way. And for that I am sorry."

Raph walked up to Donnie and said, "I'm going to go help our brothers and sister, and I'm gonna need some help. You feel like joining the fight?"

Donnie's face lit up and he smiled as he said, "Yes."

"Great," said Raph, "Now go put in your contacts and come with me to the lair to gear up."

"You got it, big bro," said Donnie, then he closed his laptop, stood up, and went to the bathroom to put in his contacts.

After Donnie put in his contacts, he and Raph left the house to go underground to the ninja lair so he could get his ninja gear. After the boys were gone, Yoshi and Shen decided to express their concerns to one another.

"I must confess, I have mixed feelings about letting him go," said Yoshi.

"As do I, my love," said Shen, "But I also have the same feeling when I allow Miwa, Leonardo, Raphael, and Michelangelo to go."

"Me too," said Yoshi, "But I also know that I do not have much of a choice with me still being too injured to fight with them."

"Until then, we will just have to trust them to come home safely," said Shen, "Also remember, it was you who trained them."

That was enough to comfort Yoshi and assure him that his children would come back safe and sound.

Out in the city, Raph and Donnie had followed the trail of truck fluid to a warehouse. Donnie was now dressed in a ninja outfit that was nearly identical to his family's, except it had purple lining, a purple mask, and a leather holder for his bo staff.

"Say, bro," said Raph, "Have you decided what you want to call yourself."

"Huh?" Donnie asked.

"Remember? While we're in ninja mode, we can't use our real names because someone could identify us later," Raph explained, "So we all use code names."

"Oh, right," said Donnie, remembering what his father said about anonymity. He started thinking about what to call himself, then he spoke up, "How about Tetsuo?"

Raph thought it over for a second, and then said, "Good one. Tetsuo it is. And I go by Kurogane."

"Yeah, I remembered that," said Donnie, "Now let's do this."

"Thought you'd never say that," said Raph, with a grin.

Together, Donnie and Raph climbed in through an open window and started sneaking around the warehouse looking for their siblings. Suddenly, they heard footsteps and quickly hid. They saw two Kraang droids pass by and Raph signaled for Donnie to sneak up and attack. Donnie nodded and the two unsheathed their weapons and attacked the Kraang.

After taking out the two droids, Raph and Donnie smiled proudly at their handiwork until they heard a voice say, "It is another one of the ones called 'the ninjas', and he has brought another one called 'a ninja'!"

Donnie and Raph turned around and saw five more Kraang droids standing behind them with guns in their hands. The Kraang fired and the two ninjas dodged to avoid being shot by the lasers, and then they used their ninja skills to take the droids down. Raph stabbed them multiple times with his sai while Donnie used his staff to take them down as well as the occasional use of the hidden blade.

The fight lasted until a Kraang without a robot body came scurrying in and screaming about something. This made the other Kraang bail before the fight could go any further.

Donnie raised an eyebrow and asked, "What was that about?"

"Who cares?" said Raph, laughing hysterically "It's funny watching them runaway scared!"

"I'm serious," said Donnie, "If something scared them, it was probably something dangerous and powerful. Like a mutant."

Before Raph could reply, they both heard the familiar screams of their brothers and sister. Knowing that they could be in danger, Raph and Donnie ran quickly in the direction came from. They kept following the screams until they found a giant black spider-like mutant hovering over a hole in the floor. It took all of Donnie's will power not to scream at the sight of it.

After the mutant jumped into the hole, Raph and Donnie heard screams coming from below that could only belong to their siblings. They rushed towards the hole and looked down to see what was happening and saw the mutant standing in front of their brothers and sister.

"Playtime's over, brats!" said the mutant, in a voice that was familiar to Raph and Donnie, the phone guy.

The spider spat acid at the trio and was about to advance on them when Raph said, "Wow, I didn't think this guy could get any uglier. Did you, Tetsuo?"

Donnie shrugged and said, "Can't say I did."

Leo, Miwa, and Mikey smiled and called, "Kurogane!"

Raph and Donnie jumped down to the spider's level and looked at him determinedly. This mutant messed with their family, so now he was going to pay. It was then that Leo was able to get a good look at Raph's partner and his eyes widened in shock.

"What're you do here?" he asked, then turned to Raph and asked, "What is he doing here?"

"I have a name. And it's Tetsuo," said Donnie, "And what I'm doing here is helping Kurogane here save you guys."

"Thanks," said Mikey, "Whoever you are."

Leo was about to say something back to Mikey when Miwa pushed him aside and said, "I don't know about Ryu, but I personally think that you've been punished long enough. Care to join the fight?"

Raph smiled and said, "You even have to ask?"

The spider mutant turned around to face Raphael and Donnie, smiled, and said, "Hey look, it's the kung-fu kid with the salad tongs. And he brought a friend with him. Nice stick by the way."

"Hey look, it's the stupid loud mouth who's about to get his butt kicked," said Raph.

"Who also happens to not know that there's a difference between Chinese and Japanese fighting styles," Donnie added.

Right after Donnie said that, the Spider mutant rolled around and circled Leo, Miwa, and Mikey while spitting acid on the floor. The acid burned through the floor and made a second hole, which Leo, Miwa, and Mikey fell through. Once they landed and rubbed their heads, Leo looked down and saw that the floor they were standing on was glass and underneath was mutagen.

Leo's eyes widened in shock as he said, "Uh team, let's not fall through this floor. Okay?"

Back on the second floor, the spider mutant looked over at Raph and Donnie and said, "Dance for me, brats!"

He then spat acid at them multiple times, and the two ninjas jumped back to avoid being hit. They wound up dropping their weapons in the process, but they managed to get some distance between themselves and the mutant.

Raph breathed heavily and said, "That is one dangerous bug."

"Actually, spiders aren't technically bugs, they're arachnids," Donnie corrected his brother, "The difference between the two is..."

"Not now!" Raph snapped.

The ninjas turned their attention back to the spider mutant, who said to them, "Watch me turned your friends into kung-pao. I'll serve 'em up with your salad tongs."

He then spat out a web and used it to slide down the hole in the floor.

"No!" Donnie screamed as he and Raphael picked up their weapons and ran after the spider.

The two slide down the web themselves after the spider mutant. Once he got the okay from Donnie, Raph used his said to cut the web and make the spider mutant fall hard to the floor; Donnie could have sworn he heard a fart sound when the spider landed face fist.

Raph and Donnie landed on his back and jumped off and stood in front of him. The spider mutant stood up and roared angrily at them. They glared at him and got into fighting stances.

The spider grinned at them and started taunting them, "Oh look, the little babies think they can take me. How cute. You think you could beat me when your friends couldn't? What a laugh."

"Remember what sensei said," Donnie whispered to Raph.

Raph took a deep breath and tuned out the spider's words. He also whispered to himself, "Like a river over stone."

Before the spider could say anymore, Raph and Donnie struck him multiple times with their weapons. At one point, he tried to grab them with his long spider led, but Raph caught one with his sais. The spider tried to spit acid at them, but Donnie blocked the attack by using the spider mutant's leg. The spider hissed in pain and backed up a bit.

He then glared at them and said, "That's some kung-fu, kids."

Right on cue, Leo, Miwa, and Mikey jumped in and stood behind Raph and Donnie. The two smirked as Raph said, "We're not 'kung-fu kid's, we're ninja warriors."

After Raph said that, all five kids charged at the spider mutant and attacked him. They all dealt multiple attacks, which knocked him back and caused him to drop his phone.

Donnie saw the phone and asked Raph, "Care to do the honors, Kurogane?"

Raph grinned and said, "With pleasure." And then he lifted his right foot high and brought it down hard on the phone, crushing it.

The spider mutant saw that and screamed, "My phone!" he then stood up and glared at the ninjas as he said, "You're gonna regret this."

He then shot out more webs and climbed back up. The ninjas climbed up and followed close behind. They followed him all the way to the roof and watched as he jumped from roof to roof until he was out of sight.

Donnie smiled under his mask and commented, "I know a nice black widow that would be great for him."

Mikey laughed a little at the comment and said, "Good one, dude. I should tell that one to my other brother."

At that line, Donnie rolled his eyes, pulled down his facial mask, and said, "Mikey, it's me."

Mikey's eyes widened in realization and he said, "Donnie?!"

"Yeah," said Donnie, "But call me Tetsuo when we're in the field."

"Do mom and dad know you're here?" Mikey asked him.

"They let me go with Raph," Donnie said.

After Donnie answered the question, Leo stepped in and to him and Raph, "Great job you two. I just wanted to say..."

Before Leo could finish, Raph shook his head and said, "You don't have to apologize to me."

Leo smiled at Raph and said, "I wasn't going to."

"Oh," Raph replied, then he looked back at Leo and said, "You do have to apologize to Donnie though. So do Mikey and Miwa."

The three looked confused and Miwa asked, "What for?"

Raph nudged Donnie in the arm and Donnie stepped forward and told them, "Being overprotective. It made me feel uncomfortable. I wanted to tell you guys before, but you were always too busy hunting Kraang."

The let that sink in for a moment, and then Mikey spoke, "Sorry, D."

Next, Miwa said, "I had no idea we were hurting you. I'm sorry, too."

Finally, Leo told Donnie, "Man, sorry, Donnie. I honestly just wanted to protect you."

Donnie smiled at his siblings and said, "It's okay. I know you meant well."

Raph them recommended something and told his siblings, "Turns out, Donnie was right about his ninja outfit. The Kraang took one look at him and assumed he was a different kid."

Leo smiled at the news and said, "Well, then in that case, we've got some changes to make." He walked up to his second brother and said, "Since you've shown great skill in battle and the Kraang don't recognize you like this, I think it would be fitting to make you an official member of the team."

Donnie's face lit up and he asked, "Do you mean it?"

"Sure," said Leo, "What do you say?"

"Yes!" said Donnie, still smiling brightly, "I will join the team!"

Leo smiled and said, "Then welcome aboard, Tetsuo."

With that, the five ninjas cheered for their newest member. Donnie was happy to finally be a part of the team, and his siblings were happy to have their brother join them.
