Inside the TCRI building, the Kraang droids have received an incoming message from their leader Kraang Prime on the view screen.

"Kraang Prime!" The Kraang cheered continually. "Kraang Prime! Kraang Prime!"

"The invasion that is known as the invasion of Earth begins now!" Kraang Prime announced.

With that, the entire Kraang droids started marching to prepare for their invasion.

"Prepare the Technodrome." One of the Kraang droids ordered.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

In the Crete Fortress, Ariana was working on a new invention inside the lab. But then, the Kraang communication orb started alerting with pink spots that caught Ariana's attention. She looked over to see her computer was uploading files of documents and images from the orb.

"What's going on?" Ariana muttered. She looked at the files and started typing codes that can translate interdimensional languages. "The Kraang Communication Orb's going haywire. Looks like the Kraang blobs are up to something big this time."

As Ariana hit the enter key with one finger, her eyes widened in utter shock as she stared at the highlighted Kraang language that were translated to English in seconds.

"I've got tell the others." Ariana said.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

In the living room, Ariana's siblings were doing their own thing in relaxation. Talia was playing on her orange console handheld game. Camilla and Casey were reading superhero comic books. Ezra and Norbit were playing an arcade game. And Kirana was finished watching the last episode of Battlestar Matrix, where Mila and her crew returned back to Earth after their final battle with a large, obese pink dinosaur-like space monster.

"What a glorious victory." Kirana smiled in awe.

"Everyone, come in my lab! I've got something extremely important." Ariana yelled from the lab.

Kirana, Camilla, Talia, Ezra, Norbit, and Casey turned their attention to Ariana as they got up and headed to Ariana's lab.

"What'cha got, Ariana?" Camilla asked.

"I have been sifting through all this Kraang chatter and I've found something that you guys should hear." Ariana explained as she was typing more codes on her computer. "Listen to this."

Ariana hit the enter key and the Kraang Communication Orb started playing the translated words.

"The final phase of the plan, known as Kraang's invasion, shall commence in the unit of time that is six hours. The Technodrome shall arrive from Dimension X through the portal." A Kraang droid's voice spoke from the Communication Orb.

"Okay, that's bad." Talia said.

"This is the final phase of the Kraang invasion." Ariana said.

"Wait a minute. I thought we were the key to the Kraang plot, including April." Kirana pointed out.

"And her sister; Macey." Ezra added.

"Although Macey is half human half mutant, there is a possibility that the Kraang are still targeting her." Norbit said.

"Maybe they got bored and didn't want us anymore." Camilla said as she crossed her arms over her chest.

"If the Technodrome comes through that portal, it would be the end of the world for all of us." Ariana summarized. "The city and the entire world."

"Great, it's an invasion." Ezra said, sarcastically.

"So what are we gonna do?" Talia asked.

"Guys, listen up." Kirana called with a determined face. "We gonna find a way to shut that portal down one way or another."

"You really expected the five of us to save the world?" Talia asked.

"Kirana is right." Sage spoke as she stood behind the teenagers. "When you first went to the city, I feared you were not ready to face the world as I did in the past. But I've realized that it was your destiny to become heroes you all have trained to be. If the fate of the world must rest in somebody's hands, I am grateful that it's yours."

The K-5 bowed to Sage.

"Then let's save the world." Ezra smiled.

Camilla, Ariana, Talia, Ezra, Norbit, and Casey dashed out of the lab to prepare for the battle, but Kirana noticed her mother's look and stepped forward towards Sage with a worry face.

"What's wrong, mother?" Kirana asked.

"Kirana, the most important thing is to complete your mission with the world at stake." Sage said.

"Yes, mother." Kirana said with a nod.

"No matter who or what you have to sacrifice." Sage finished.

Kirana looked away in thought for a second and then looked back at Sage with an understanding nod.

With that, Sage made her way to the dojo.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Meanwhile, the K-5 was preparing for the plan to finally take down TCRI and the portal to Dimension X. Kirana was going through plan ideas. Ariana was building a few weapons in her lab. Ezra was gathering some spell equipment and learned quick spells. Camilla was pumping her strength with large vinyl dumbbells. Talia was performing her acrobatic skills.

The K-5 stood in front of Sonicruiser. Norbit gave hugs to the mages, Casey gave the girls a good luck hug, gave Ezra a fist bump, and Sage bowed her head.

"Alright, ladies and gentlemen. Let's go save the world." Kirana said to her siblings.

With that, the K-5 entered the Sonicruiser and drove towards the city.

Sage, Norbit, and Casey watched the K-5 drive off in the futuristic car.

"Hey, Sage, can I ask you a question?" Casey asked.

"Of course, Casey." Sage answered.

"Why don't you go with them?" Casey asked his question. "I mean, don't get me wrong. The K-5 are out there risking their lives and they could use your help in this time of crisis."

"Well, I might be their mother and teacher, but there are some things in my past I cannot face." Sage replied calmly.

"But why?" Casey asked again.

"Come with me." Sage said with a deep sigh.

With that, Sage walked off to the dojo with Casey and Norbit behind her.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Outside, the K-5 drove the Sonicruiser into the streets of New York. They finally reached TCRI as Kirana parked the black vehicle into the dead end alley.

"All right, guys, we're gonna keep it simple. We go to TCRI and we use the micro-fission omni-disintegrator, which Ariana calculates that is powerful enough to destroy the portal with a single shot." Kirana revised.

"Got it." Ariana, Talia, and Ezra nodded in agreement.

"But are you sure this plan gonna work, Kirana?" Camilla asked.

"It has to work." Kirana replied with a firm face. "I know I will."

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Back in the Crete Fortress, Sage waved her magic on a large transparent bubble in the dojo. Casey and Norbit watched the bubble displaying an event on a jealous Rozu attacked Sage in the family's burning home. During their battle, Caesar saved Sage from Rozu's fatal attack. That allowed Saldana survive, but she mourned for his death. The sound of Sage's scream for her husband's death made Casey and Norbit feel sympathy for the white mage.

After the story ended, Casey and Norbit looked back at the saddened Sage. Norbit gave Sage a hug to comfort her, to which the white mage smiled a little.

"I know you want me to help my children, but I couldn't face my past no matter how much I want to." Sage said.

"I understand your fear, Sage." Casey said as he made his way to the dojo slide door. "But I can't just sit around and do nothing."

"Casey, where are you going?" Sage asked.

"I'm gonna help the K-5." Casey replied. "I know you think it's dangerous for me to head out the city, but you have to trust me."

"Alright, but promise me you be careful out there." Sage said.

"I promise." Casey smiled with a nod.

"I will go with Casey to help my best friends." Norbit said.

"Ok." Casey said. "Let's go, Norbit."

With that, Casey and Norbit exited the fortress and made his way to the city. Casey stood on a building rooftop and took his hockey stick with his mask on his face.

Before he and Norbit can head out to find the K-5, two Shadow Ninjas appeared out of nowhere and grabbed Casey's arms besides him. Two Shadow Ninjas then grabbed Norbit's arms beside him. Casey was trying to break free, but he wasn't strong enough.

"Let me go, you ninja clods!" Casey cried.

Then, Casey and Norbit saw Kuro walking toward him with two Nanocats on his side.

"Sup, hockey boy." Kuro greeted with a grin. "Miss me?"

"Yeah, only when we have our bro time." Casey replied.

"You two take the message to Sage." Kuro ordered the Nanocats.

The Nanocats bowed her head and walked their way to Sage. The Shadow Ninjas pulled Casey and Norbit to Kuro as Casey looked at him with a glare. But Casey smiled secretly at Kuro, who was grinning in the same secretive manner before looking back at his Shadow Ninjas.

"Let's go." Kuro ordered.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

In the TCRI building, Phantom took down of the Kraang droids with a barrage of quick slashes. She noticed Ms. McGuire was standing in front of her as she transformed her arms into laser cannon.

"Surrender now or face my cannons." Ms. McGuire demanded.

"Surrender is not in my memory banks, pal." Phantom said with narrow eyes.

Phantom and Ms. McGuire charged forward to engage the robotic battle.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Meanwhile, the K-5 soared their way to TCRI in the air. Ariana created five airboards for everyone to infiltrate TCRI from the roof with incredible flight. Kirana's airboard was light blue with emerald green spades as foot pads on a black plate in the center of the top surface. Ariana's airboard was bright lilac with brownish green clovers as foot pads on a black plate in the center of the top surface. Ezra's airboard was light turquoise with sea green stars as footpads on a black plate in the center of the top surface. Camilla's airboard was bright scarlet with dark green hearts as foot pads on a black plate in the center of the top surface. Talia's airboard was tangerine with light green diamonds as foot pads on a black plate in the center of the top surface.

"Nice work on the boards, Ariana!" Camilla shouted to Ariana with a grin.

"This is epic!" Ezra cheered.

"Yeah, this is awesome!" Talia agreed.

Ariana grinned at Camilla, Talia, and Ezra with a wink.

"Alright, guys! Let's go this!" Kirana said.

The K-5 approached the Kraang's base and landed on the highest part of the building roof. They noticed a pigeon was staring right in front of the security camera on the corner. Kirana, Camilla, Ariana, Talia, and Ezra walked by the security camera undetected, but the blue mage kunoichi halted herself and gasped suddenly that caught her siblings' attention. She felt a bright yellow aura and a bright pink aura within the Kraang base and shook her head for that sudden feeling.

"What is it, Kirana?" Talia asked.

"It's April!" Kirana replied with a sharp gasp. "The Kraang captured her and her little sister; Macey! We have to destroy the portal and save April."

"And how are we gonna do that without letting April and Macey see who we are?" Camilla asked as she placed her hands on her hips.

"She has a point." Ezra said. "They'll freak if they see who we are. How can we act like different ninjas?"

"With these." Ariana answered. She snapped her fingers and five black metallic masks appeared in her hands. "I know just in case April or Macey spotted us, we will use these masks to disguise our voices. That way they won't recognize us once we were inside."

"Smooth thinking, Ariana." Talia grinned.

"It's what I do best." Ariana smirked proudly.

The K-5 put on the masks on their faces. Kirana's black mask has several neon blue linings at the center. Ariana's black mask has several neon purple linings at the center. Ezra's black mask has several neon teal linings at the center. Camilla's black mask has several neon red linings at the center. Talia's black mask has several neon orange linings at the center. The K-5 powered their boots with their elemental magic and began propelling over the Kraang base as they jetted down to the portal.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Back in the Crete Fortress, Sage was meditating under the great tree inside the dojo. She heard two robotic meowing behind her and immediately stood up as she aimed her white magic at the Nanocats that were approaching her innocently.

"What kind of trick is this?" Sage wondered as she took a step back from the Nanocats.

One Nanocat activated a hologram of Lady Shade in front of Sage.

"Greetings, Sage." Lady Shade spoke.

"Shade?" Sage gasped with wide eyes.

"I was willing to leave you grief for the end of the Magnolia Clan. But I never imagined you would train your own children to recreate your clan once more. I have Casey Jones and Norbit in my grasp. If you value their life, you will come and face me one on one. So, we can finally finish what we started years ago." Lady Shade challenged.

With that, the holographic Lady Shade disappeared from the Nanocat.

Sage then noticed the other Nanocat was scanning the location of the fortress from its red glowing eyes. The Nanocats ran out of the dojo, but Sage destroyed them instantly with one white energy blast.

"If Shade wants to face me one on one, so be it!" Sage declared.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Back in the TCRI bulding, the K-5 quietly snuck into the main base. They saw the Kraang droids are waiting for the portal.

"What? The portal is not here." Ariana whispered.

"Bummer." Camilla said with a deadpan face.

"And it's a good thing that I made these Kamikaze Grenades after all." Ariana said.

"What does it do anyway?" Talia asked.

"The Kamikaze Grenades can disintegrate anything within a certain radius around the target with an explosive charge." Ariana explained.

"Then, how come you didn't locate the portal in the building with the communication orb?" Kirana asked Ariana.

"Obviously, we were in a hurry, so I didn't have time to do that!" Ariana shouted frustratingly.

"You just had to shout something!" Ezra said, irritated.

Then, the Kraang droids heard Ariana's voice and aimed their laser guns to fire neon pink blasts at the K-5.

"Forget this." Camilla said to her siblings. "Let's make this mission a lot more fun."

Suddenly, the K-5 jumped down to the floor and charged forward to battle with the Kraang droids.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Meanwhile, Masque and Inque were waiting in the throne room for Sage's arrival. Casey was sitting on the throne chair bounded by tight chains as he struggled to break free from the chains on his own. Norbit was in chains next to Casey.

"So, why would Lady Shade fight this Sage anyway?" Masque asked Inque.

"Sage is one of the best master mages in history. She and Mistress Shade trained in the same ninja clan many years ago." Inque explained. "They used to be like sisters until Shiroibara Sage betrayed her. She may have powerful skills as Mistress Shade, but she doesn't have the will to finish the fight."

Then suddenly, Inque and Masque heard the sound of fighting coming from the other side of the door.

"It can't be." Masque gasped.

"She's here!" Inque exclaimed.

Inque and Masque got into their offensive stances as they were ready to take on Sage on their own. As the door opened wide, Sage appeared and walked slowly in front of the mage mutants with all of the Shadow Ninjas went unconscious behind her. Inque shapeshifted her arms into razor-sharp claws and charged forwards towards Sage while stabbing the white mystics rapidly with her claws. But Sage swiftly dodged Inque's claws with ease and enhanced her hands with white energy to deliver massive blows at the ink mystic mutant. Masque charged forward and fired a beam of ghost white energy at Sage, who moved out of the way with remarkable speed and stabbed her right hand at the ghost mage mutant before blasting white energy lasers from all of her fingers that sent her towards the ground. Inque and Masque got back up on their feet with a glare. As they charged forward to attack Sage together, Sage performed a jumping knee strike on the mage mutants' chest and launched them upwards as she somersaults back to the ground. As Sage landed on her feet, she drew daggers made of white magic and leapt up towards the mage mutants as she quickly delivered a series of slashes from multiple directions before slamming them into the ground. Inque and Masque groaned as they went out unconscious on the ground.

"That. Was. Totally. Wicked!" Casey cried with a huge smile.

"That was very amazing combat." Norbit said.

"Don't worry, I will get you and Norbit out, Casey." Sage assured.

Sage ran over to Casey and lifted one glowing finger. She took a careful aim and shot a tiny white energy bolt at the chains, disintegrating them instantly and allowing Casey to get off of the throne room. Sage then did the same with Norbit and walked away from the throne room.

Then suddenly; Sage, Norbit, and Casey heard Lady Shade's giggling as numerous flaming torches lit up and lined on the walls at either side of the throne room. They looked up to see Lady Shade dropping down to the ground.

"Hello, Shiroibara Sage. I am so glad you accepted my invitation." Lady Shade spoke. "You can have Casey Jones and Norbit back. They have done their job leading you here. Especially when the Kraang should have capture your children by now."

"What did the Kraang done with my children?" Saldana shouted. "Do you have any idea what you've done? You put the entire world close to destruction all because of your vendetta against me?"

"Yes." Lady Shade answered. "The Kraang wants to use your children's magic for their invasion, but I really don't care about all that. I demand an opponent worthy of strength and now I can finally crush you like the vile insect once and for all."

Sage narrowed her eyes at Lady Shade with a glare. She lifted her hand and opened a white swirly portal behind Casey and Norbit.

"I'm creating a portal back to the fotress, Casey." Sage said. "Go with Norbit now! This is my fight!"

"Okay." Casey said with a nod. "Kick her butt, Sage."

"Will do." Sage grinned.

"Be careful, Sage." Norbit said.

"I will." Sage assured.

As Casey grinned back with a thumbs-up and walked into the portal with Norbit, Sage snapped her finger to close the portal behind her and looked back at Lady Shade with a dangerous face.

"You have continue to channel your vengeance as your strength, Shade." Sage declared. "No matter how many years of your consuming revenge, your defeat will always be the same!"

Sage and Lady Shade levitated high above the floor as they formed a ball of magical energy around themselves and locked each other into a vicious battle.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Back in the TCRI building, the K-5 finished taking down the Kraang droids with their magic.

"Well, that was easy." Ezra grinned.

"Uh, guys?" Ariana called. "We have a problem!"

The K-5 looked at the window and saw a pink energy beam firing into the sky. Their eyes widened wide when they saw a large metallic silver sphere-like spaceship emerging from the sky through the opening portal. The spaceship has multiple protruding spikey points and an huge purple eye-like shape in the center.

"O. M. G!" Talia gasped.

"We have to get out of here now!" Kirana said.

Kirana screamed out loud as she got blasted painfully in the back and collapsed straight to the floor.

"Kirana!" Camilla shouted.

Camilla, Ariana, Talia, and Ezra looked forward to see the last four remaining Kraang droids standing right in front of the downed Kirana with short thin silver sticks in their hands. Before four mages can attack with their magic, the Kraang droids swiftly electrocuted them and the mage kunoichis and mage ninja fell down one by one on the ground unconsciously.

With a strained groan, Kirana lifted her head a bit and opened her eyes to see four Kraang droids gathering around her and her younger siblings.

"Take the ones known as the K-5 to the room where the ones known as April O'Neil and Macey O'Neil have been contained for Kraang Prime." One Kraang droid ordered.

Kirana's view went black as she passed out.
