Here it is. The final chapter to one of the most hyped of my fanfics that I have seen so far. And I know as time ticks by, my stories will get better as long as some ideas pop in my head. ;)

But it's time to end this. Enjoy it! :D

*scene: Deepsea Metro Central Station*

After tons of walking, Redd and Sonic finally make it to the central part of the mysterious Deepsea Metro. It was pretty chilly, especially considering it was nighttime out, so Sonic decided to wear a hoodie. And Redd felt fine since he was wearing his specific Hero Gear.

They had their hands tight around their specific weapons, and their ink tank strapped on tight. They were ready for what this place has to offer.

"So, are you sure that they're here?" Sonic asked.

"Well, one of my friends have been here before. And from some further exploring when coming back, he told me that there is a laboratory somewhere around here." Redd explained.

"So you're experienced with this then." Sonic pointed out.

"Not particularly," Redd reminded, "If it's the Deepsea Metro... well, I've only been here once, and I barely got to explore it. But battling however... he, I battled lots of Octarians during my times as Agent 4. So these 'sanitized' ones won't make a difference."

"Yeah, that makes sense." Sonic said.

"Yep. But let's not waste anymore time. We gotta find that lab." Redd responded. And they began looking around the Metro. In search of it.

"Need some help, you two?" A voice asked. Redd and Sonic turned to a parked subway train that was standing there, with the door open. Then, something slithered over near the door.

It was a small, blue sea slug with a tiny conductor's cap.

"Uh, yes we do, uh... sir. We need some help with something." Sonic replied, but he felt kinda confused from what he was seeing in front of him right now. A sea slug of all things.

Well, at least it'd be better than an evil Octarian for once.

"You can call me C.Q. Cumber. I am the conductor of this train," The sea slug explained, "This subway here is connected by many lines in the Kamabo Corporation. But ever since some... *ahem* situations happened, Kamabo was running slow. But the subway still is running."

"So you know where everything about this 'Kamabo' now?" Redd asked.

"Correct," C.Q. Cumber replied, "You see, after Number 10,008 got all four thangs, he managed to be the first one to ever reach the promised land. When he came back, he told me everything that happened. It turns out... the chief of the Kamabo Corp. was tricking these fellow applicants to be part of his selfish desires. So now this subway only goes as a mode for transportation. You know, for the denizens of the deep."

"What exactly did the chief do exactly?" Sonic questioned. One of the spikes of C.Q. extended, creeping Sonic out a little. The slug pointed to a bunch of giant machine parts, along with broken glass.

"You see that over there? That's what the thangs form into," C.Q. explained, "Number 10,008 told me that those other applicants, including him, was tricked into going inside. Everyone that got in the blender has been grinded into raw material... except 10,008, of course. But still... I had no idea what the chief's true intentions were. Heck, I don't think I ever saw him in person."

"Oh gosh. That's so sad." Sonic said in a worried tone. It's true, hearing about all these innocent lives that were taken away by the telephone.

"Did Agent 8 tell you about who the telephone really was?" Redd asked as he stepped closer.

"Indeed. He told me that the phone- or... Commander Tartar, was using the lives of the underground dwellers here to destroy the world. But as it turns out, Number 10,008 prevented it from happening." C.Q. responded with a small chuckle.

"Listen. Somehow, Tartar came back, and he took control of someone I love, along with kidnapping my friend's parents. We need to get to a laboratory of some sort. Do you know where it is?" Redd demanded an answer.

"The Kamabo Laboratory? Sure, I know where it is. Now that Tartar was defeated, I managed to know where the location of it is." C.Q. answered. He extended his arm again.

"Take the tunnel right over here. When you see a green light with a door, that's where the lab is. Be careful, though. Even though Tartar is gone, but revived in your words... there's still some... threats that hang around." The sea slug warned.

"Thank you, C.Q. Cumber. That's all we need. I'll have to go now, we're in a hurry." Redd said, and then ran to the tunnel. Sonic immediately followed him to not get left behind.

"Good luck, you two." C.Q. called out.

*2 minutes later*

Redd and Sonic see the green light. Even though it was nearly pitch black, the door was still seeable.

"Alright, this is it. The lab is right here." Redd said.

"Okay." Sonic responded with a slight nod. Sonic put his hand on the knob, and was about to turn it and go inside the room. But before that happened...

"TARGET ACQUIRED." A robotic voice yelled. The two Inklings turn around, and they see a bunch of sanitized Octarians. It was ranging from Octotroopers, Octosnipers, Octocommanders, Missile Octocopters... even Octolings.

"Commander Tartar is busy with his situation right now. He can't bother to have you two get in his way." One of the Octolings explained, with the minor Octarians letting out angry gurgling noises.

"We have to go now. W-We have to hurry." Sonic exclaimed.

"Ope the door, and we'll be forced to shoot." The same Octoling commanded as each sanitized Octarian put their weapons up.

"Oh yeah? Well then, how about you make us?" Redd threatened.

"SEEK AND DESTROY!" They all screamed, and then they began attacking with their designated weapons. Redd quickly grabbed his Hero Shot and began shooting the many Octarians that were surrounding them.

"Hey, Sonic! I could use some help over here!" Redd shouted.

"You got it, Redd!" Sonic yelled with a smile. He twirled his Dark Tetra Dualies in his hand before shooting ink from them and rushing towards the many Octarians.

Sonic threw and Autobomb at one of the Octolings. Since that one Octoling wasn't paying attention, she got splatted.

"NEVER RETREAT, NEVER SURRENDER!" Another Octoling screamed. But the Inklings weren't backing down one bit.

More and more time passes by. Those sanitized Octarians didn't stand a chance. There were only a few more left before all the attackers are gone.

Ding!

That sound. Redd and Sonic's specials are ready. With each weapon they are using, they have the Splashdown as their special.

"Alright, Sonic. Hold my hand." Redd said.

"Why?" Sonic asked.

"Trust me on this. I did this with my sister to defeat Tartar the last time." Redd responded. Sonic smiles and nods, then he holds his friend's left hand with his right.

"Now. Let's use our specials at the same time." Redd explained.

"Oh! I see where you're getting this at! Yeah, let's do it!" Sonic cheered. And the two squids activated their specials at the same time.

The remaining Octarians screamed, and they began to run away. But the time that Redd and Sonic landed with the Splashdown at the same time, the knockback of the ink was so big, that each of those Octarians were splatted easily.

"Booyah! See, now that's how you do partner missions." Redd exclaimed excitedly as he pumped his fist.

"That was cool! We have to do that again sometime!" Sonic yelled happily.

"We will. Now let's go save your parents and Marie." Redd said, and they go inside the door.

*scene: inside the Kamabo Laboratory*

The walls were white. It was way better than in that pitch black tunnel. Plus, they could actually see.

"Redd, look! Over there!" Sonic shouted as he grabbed Redd by his arm. Sonic pointed in front of him, and Redd was surprised by what he was looking at.

Sonic's parents: each in a different tank. They were floating in the sanitized ink, unconscious.

Redd frowned and looked around. He knew that it wasn't going to be this easy.

"I'm gonna go over and rescue them." Sonic said, and then he walks over to the tube. Redd just stays still, wondering where Marie is at.

Redd kept on looking. But he saw nothing. As Sonic was walking along, Redd could've sworn he heard some charging sound.

Then his eyes widened when he saw a teal line that was making its way towards Sonic. Redd knew it would be over if it landed. So there was only one thing he could do.

"LOOK OUT!" Redd screamed, as he ran towards Sonic. Before he could respond, Redd pushed him back. And a large boom sound was heard. The two squids looked behind them, and there was a straight line of sanitized, teal ink.

They stand up, and the next thing they hear was an evil laugh. Both of them got worried. Especially Redd, since he heard that voice was a mixture of Marie's.

"Well, well. You two squids actually came." The voice said. Sonic and Redd looked up, and there was a tall pillar with someone standing on it. The being turned into squid form and super jumped, and landed right in front of the two.

Redd got surprised. Tartar was controlling Marie. Her lime green ink color replaced with teal... everything was teal on her. The outlines of her dress, her leggings, her eyes... even some parts of her hair (not the gray parts).

"Tartar! What did you do with Marie?!" Redd yelled.

"Heh heh... nothing in particular, really. I just decided to pick her as my victim to get to you two." Tartar replied.

"You are an awful being! You've gotten way too far with your evil doings!" Redd shouted.

"Give my parents back!" Sonic commanded.

"Sorry, seafood. That's not happening," Tartar said, "I got you two here now, so now it's time for my revenge. I'm starting with Agent 4 because of how special he seems to be. And what better to get to him than to lure him here? And I used the one he loved in order to do it! Once I'm done with these two squids, I'm gonna make them under my control, and then Inkopolis will be all MINE!"

"How could you do such a thing?!" Sonic shrieked.

"This is to avenge the humans. For everything you pathetic, dumb life forms have to offer on this planet." Tartar exclaimed in a disgusted tone.

"I can't let you do that, Tartar." Redd said.

"OH, REALLY? You're gonna try and stop ME?" Tartar laughed. But then he got surprised when Redd knocked him down.

"GET OFF OF ME, YOU SLIMY LITTLE SQUID!" Tartar demanded.

"You're gonna pay for what you did. I already lost my parents. I'm not gonna lose another person that I love." Redd said angrily. Tartar struggled in the red Inkling's grasp. Redd kneeled down and neared his face to Tartar's left ear, where the goo wasn't in for once.

"Marie... if you can hear me, hang in there. I'm gonna get you out of this maniac's control." Redd whispered. Tartar stopped his struggling for a second. There was a surprised look on the face.

The eyes were golden again, but every other trait was still teal.

"R... Re... Re-e... ed...?" Marie's voice was heard struggling to speak, as she was still heavily under control by someone.

"Just hang tight." Redd said softly. But then Tartar got full control again, the eyes turning back to teal. Tartar screamed and knocked Redd back.

"As long as I am still here, you aren't gonna save your little girlfriend!" Tartar yelled.

"Well, we're experienced with battling, Tartar! Don't expect us to et you go so easily!" Sonic shouted.

"I don't expect you to anyway. Prepare to be the spectators of the image of my new world!" Tartar laughed, and then grabbed his Hero Charger.

"This ends now." Redd said quietly.

"And it will end with me as the victor." Tartar snapped, and began aiming at Redd. But luckily, Redd inked a straight trail, then turned into his squid form to swim away. Even when tartar was still aiming for him, Redd barely dodged out of the way.

"Submit to your demise!" Tartar demanded.

"NEVER!" Redd screamed back. Tartar noticed an Autobomb by him, so he jumped out of the way before it exploded.

But then a Burst Bomb was hit, and Tartar looked at Redd, who had a smirk on his face.

Then Sonic began shooting from his Dark Tetra Dualies. Tartar took some hits, before blocking the ink with the Charger.

Tartar threw the Charger directly at Sonic, hitting the squid in the face, knocking him back.

"That's what you deserve for messing with the best!" Tartar yelled, and then laughed at him. Redd knew this was gonna be a tough battle.

Redd makes a circle of red ink with his Hero Shot, and even went for the walls. Then he took a quick dive in his ink to refill his tank.

Tartar looked at the red ink, and made a gagging sound.

"How DARE you ruin this lab?" He exclaimed.

"It's called gaining momentum. With this, you'll not be able to hit me easily." Redd said with a smirk.

"You'll find out what happens when THINGS GET UGLY!" Tartar screamed, and then he takes off the dress. Now the outfit that Tarie was wearing is similar to what Callie wore when she got squidnapped, except every pink part was teal (why would it).

Redd got surprised by seeing that.

"What the carp is this telephone thinking." Redd thought, an unamused look seeing that it came from this maniac.

Tartar grabbed a whistle, and then blows it. 3 sanitized Octolings came to assist him.

"ATTACK THESE OUTSIDERS!" Tartar commanded. And the Octolings began attacking the squids. Redd was dealing with the Octolings. Sonic was left faace-to-face with Tartar.

"Sonic! For a quick tip, aim for the goop on the side of Marie's face! That's how Tartar is controlling him!" Redd yelled.

"Okay, Redd!" Sonic called out.

"Don't bother giving advice! I'm still here, and that's how It'll always be!" Tartar shrieked. Sonic kept on inking, and runs back to wait to get a hit on Tartar.

Redd tried to run over to assist Sonic, but two of the sanitized Octolings grab him.

"Let go of me!" Redd yelled, struggling in their grasp.

Tartar aims with the Charger, and kept on looking at Sonic to snipe him. Sonic jumps high in the air by morphing from squid to kid, and Tartar releases the trigger. It wasn't a direct hit, but it was enough to sent Sonic flying back.

But Sonic grabbed his Dualies and shoots ink at the goop around Tartar's right ear. As the ink made contact, he let out a scream.

"ACK! Not there! Anywhere but there!" Tartar yelled in pain. Sonic smiled, since now he knew where Tartar's weak spot was. Meanwhile, Redd kicked one of the Octolings, forcing the other one to let him go. Then Redd threw two burst bombs at the Octolings, making them fall. Redd makes a small red ink trail, and turns into his squid form and swims in it.

Redd grabbed Tartar from behind, and shot a bunch of red ink at the goop around the ear.

"CEASE, AGENT 4! You have no place in this world!" Tartar shouted.

"Everyone's lives matter. You've taken Marie under control, just to use her to get your little 'advantage'." Redd said mockingly. The eyes are gold again. Marie was slowly breaking free from every touch Redd has.

"H... He... l... p..." Marie uttered.

"Fight it, Marie. You can do it." Redd whispered softly. He felt something wet on his cheeks. Redd immediately realized it was tears. The feelings of seeing his girlfriend slowly breaking free from the bad guy made him have so much hope.

The eyes are teal again. Tartar was fully under control. He kicked Redd in the stomach, and he yelled loudly. The two Octolings from earlier got up, and they were rushing towards the two Inklings.

"You got nowhere to hide. Give up now before you face something that you will regret." Tartar warned.

"I won't let you." Redd said as he wipes his tears away.

"Yeah! Tell him, Redd!" Sonic yelled, and then shoots more ink from his Dualies. Tartar took the hits, and then began aiming his charger at the two.

Redd and Sonic were screaming as they began to run away from each of those hits. Tartar even tried throwing a Splat Bomb. That did some damage to the two.

Redd gripped his Hero Shot tightly, and shot at the remaining Octolings. They got easily splatted.

"This battle ends here, Tartar! You will NOT destroy our world!" Redd screamed. And he let out a battle cry as he and Sonic ran to Tartar.

"D... Do... o... n... t..." Marie's voice stuttered. One of Tartar's eyes were the normal gold before turning nasty teal again.

Tartar threw a Splat Bomb on the ground, so Redd and Sonic ran back before it explodes.

But after that, four more sanitized Octolings grabbed the two squids out of nowhere. Two grabbed Redd by both of his arms, and the other two grabbed Sonic by his arms.

Both of them struggle the hardest they can against those tight grips.

"I already told you. This battle ends. With me as the victor," Tartar said, "You were foolish to try and stop me. You failed. Miserably. Now prepare to see your wonderful Inkopolis under my control, with me as its king."

"No! Don't destroy Inkopolis! You don't know how many lives will be destroyed as a result of this!" Sonic cried.

"Oh, of course I would no. Inklings and Octolings are the species that aren't worth living for. I'm here to make the world a better place." Tartar sighed. Then he grabs his Charger. Redd's and Sonic's eyes widened. They were about to be splatted for good, since there was no available respawn pad nearby.

"Farewell, you little, dumb squids. You're gonna be the first to be gone as I make way for the new world. Goodbye forever." Tartar said with an evil smirk. The smirk turned into a frown as the left eye was gold.

"F... For... give... me..." Marie let out some words, and lets a single tear roll down her cheek. Then that eye was teal again. Tartar charged up a big shot, and aimed it at Redd. He and Sonic closed their eyes, awaiting their fate.

But before Tartar can end them for good, a swing of magenta ink was shot at him, making him back up.

"WHAT?!" Tartar screamed.

"Not so fast!" A female voice yelled. Everyone looked up. The voice turned out to be Callie, and she was in her Squid Sister outfit. Pearl and Marina were also beside her, in their casual uniforms.

"Why don't you pick on someone your own size?" Pearl teased with a wide smirk.

"Callie! Pearl! Marina!" Sonic cheered.

"You came to help us!" Redd added. The three idols jumped down and held their weapons up. Callie wielded a Splat Roller, Pearl had her Splat Dualies, and Marina has a Tentatek Splattershot.

"How DARE you interrupt my plan? I was this close to gaining control of your dumb little city!" Tartar complained.

"You are doing that in the most wrong way possible! And you took control of my cousin, for crying out loud!" Callie yelled.

"We've defeated you before, Tartar. We'll defeat you again." Marina snapped.

"Get ready for a great splatdown!" Pearl shrieked. For the idols, their hair began to glow, knowing that their special was about to be ready.

Pearl started with her Tenta Missiles, which is Redd's least favorite special weapon in his opinion. She aimed each missile at the Octolings.

The sanitized Octolings let go of their captives, and they ran away. But the missiles were faster, and they caught up to the Octolings and splatted them. Redd and Sonic backed up to devise a plan as the idols attempted to fight back.

Then Marina activates her Inkjet, and started shooting at Tartar, who tried to shoot back. After all, Marina was a bit vulnerable since she's flying in the air. But she was already experienced in stuff like this.

As Tartar was knocked back from enough shots, Callie activated her special from her Roller: the Killer Wail, one of the specials that is no longer being used.

"Hey, Cal! Let me help ya out there!" Pearl insisted.

"You got it!" Callie responded with a smile and a wink. They stand behind the Killer Wail, with Tartar's eyes widening.

"No, not again! Nope, nope nope nope nope, so much NOPE!" Tartar ranted as he tried to run away.

"BOOYAAAAAAAAAAAAAAAAAAAAAHHHH!" Callie and Pearl screamed in unison, letting the attack go out full force. Tartar got caught in it. Once it was over, Tartar lays on the floor. He hasn't let go of his captive yet.

"You're not gonna control my girlfriend any longer." Redd said angrily. His special was ready as well. So he immediately started a Splashdown.

"Oh snap." Tartar mumbled, and attempted to run away and grab the Charger. But Redd's special landed, and it sent Tartar flying.

Sonic looked, and then held and Autobomb in his hands. It is up to him to finish Tartar off.

"Gotta go for the goop on the side of the ear." Sonic thought, and then threw the Autobomb. It walked towards where Tartar is gonna land.

And once Tartar landed back on the floor, on his back, the Autobomb exploded, disintegrating the goop.

"GRAAAAAAAAAAAAAAAAAAAAH!" Was Tartar's last scream before he is completely gone. And once the goop disappeared, Marie is back to normal, but lays down on her back unconscious.

"YEAH! We did it!" Pearl cheered, and everyone else cheered with her.

"Phew. That sure was a tough battle." Sonic said.

"Definitely. Luckily, we came in to rescue you in time." Marina responded.

"Word." Pearl added. They all heard small groaning. Marie raised her head up, finally waking up from the amount of attacks.

"MARIE!" Redd and Callie yelled in unison, then they ran to her, and helped her up.

"Marie? You alright?" Redd asked as he puts his right hand on her back, and his left hand on her left arm. Marie fully wakes up and looks at Redd and Callie.

"You don't have to worry about me. I'm fine." Marie said with a small chuckle.

"I'm so glad you're alright, Marie! I was so worried about you when you weren't coming home!" Callie cried as she hugged her cousin tightly.

"Oh, Callie... you were always the one to get worried easily." Marie teased as she gently hugs back.

"I never knew that Tartar would be that evil enough to try and pick you out of everyone else." Redd pointed out.

"I guess he just did. He probably didn't have any other choice. But still..." Marie mumbled.

"What?" Redd asked.

"I should't have let Tartar fully control me." Marie admitted.

"Marie, you are a strong agent. Even stronger than me," Redd said, "Even though Tartar was controlling you with all his strength, I knew I had to be there to help you fight it. And it managed to work a little. If I wasn't there, then Pearl, Marina and Callie won't come to save us in time."

"Heh, you have a point, Redd." Marie responded with a smirk.

"Uh... Marie? I'm wondering... why you're wearing THAT?" Callie asked, as she pointed at Marie's outfit. It was still that half-naked one, and Marie was surprised she's wearing it.

"Why the carp is Tartar such a PERVERT?" Marie ranted.

"Yeah, I agree. Your normal dress suits you perfectly." Redd complimented.

"Oh, Redd. I noticed you aren't... depressed anymore." Marie pointed out.

"Heh, that's right! I'm now my excited, awesome self again!" Redd shouted excitedly, and then jumps high in the air and turns around, turning his head back at the Squid Sisters.

"WOO! REDD'S BACK!" Redd screamed while putting his hands high in the air. The Squid Sisters just roll their eyes at the playfulness. Marie slowly walks over to the fourth Agent.

"Well, if he's back... then I'm sure he would give me a kiss after all that." Marie teased.

"He most certainly will." Redd said with a smirk. And then their lips lock on, each of them putting their hands on each other's body. Their tongues dance around, small moans being heard.

After 10 more seconds, they finally stop. Sonic smiled at the sight, happy to see that everyone is alright. Marie is saved from Tartar, and Redd is no longer feeling depressed.

Sonic saw that Pearl and Marina were walking towards him as well.

"We're happy to see you okay, Sonic. Along with Redd and the Squid Sisters. It was really worth it." Marina said.

"Yeah! And we're alright, even through that whole battle! Good job on destroying Tartar with us!" Pearl complimented.

"Oh, heh... it was nothing." Sonic replied bashfully. He got surprised to see the Off the Hook idols hug him, making him blush very brightly.

"It was anything BUT nothing! You saved Inkopolis if anything!" Marina exclaimed as she kept in hugging him.

"Just like we did with Agent 8 before!" Pearl added. Before Sonic could respond, there was the one thing that just happened that he will remember for a long time.

Both Pearl and Marina kiss him on the cheek. Sonic's blush got even brighter, and he passed out in the process.

"Hee hee... come on, let's take him back. We've each had a long day." Callie insisted.

"And his parents, too. That's the other main reason we came here." Redd added.

*8 minutes later...*

"Hey, he's waking up!" Redd exclaimed. Sonic slowly opened his eyes. They fully opened once Redd lightly shakes him.

"Heh, Sonic, you alright, man? You passed out for, like, 8 minutes." Redd laughed.

"It's... hard to explain." Sonic admitted. Sonic looked around, and saw the four idols were there, with Marie wearing her kimono again. Redd was there, and...

Sonic's parents were there as well, and they were alright.

"We're happy to see you actually made it out. And you even helped save us, sweetie." Sonic's mom said.

"Yeah! I never knew you had the guts to actually come save us!" Sonic's dad added with a hearty laugh.

"Heh, I couldn't have done it without Redd, the Squid Sisters, and Off the Hook." Sonic confessed. He also noticed that it was still nighttime. Around 2:00 AM.

"So, why are we here again?" Sonic asked.

"That's because we have a special gift to give to you." Marina replied.

"And it's a very worthy one for that matter." Marie added.

"Sonic, this is one moment that you cannot turn back on. You've helped save Inkopolis, your parents, and Marie, and we knew we had to give you something special." Redd said.

"I want to see what this gift is." Sonic said excitedly. And then confetti was thrown at him as cheers were heard.

"Congratulations, Sonic! Because of your awesome efforts... we have officially decided to make you Agent 10 of the New Squidbeak Splatoon!" Redd offered.

"O-Oh my gosh." Sonic mumbled, very surprised by that. And then he shock went even higher when both of his parents hugged him.

"We're so proud of you, son! This is a great achievement!" Sonic's dad cheered.

"We hope you'll do the best you can as being part of this major group!" Sonic's mom agreed. Sonic slightly smiled and embarrassingly chuckles.

"G-Guys, stop. You're embarrassing me." He said. Everyone got a good laugh at that.

"Anyway, we should go back home. It's getting really late." Redd insisted.

"Sure." Everyone else replied. And so, they all leave Octo Canyon, happy that they were able to save the day.

Redd's depression has faded away, and it was all worth it to save his friend's parents, and his girlfriend. While his parents are gone, at least he'll one day know that somewhere where no mortal being can go to...

Redd's parents are up there, smiling widely.

This was one of the best days to have such a great happy ending.

A/N: And that's all for Depressink :D. Before I go, I bet some of you will be wondering if there will be a bonus chapter. The answer is yes, there will be. I'm gonna try and make it ASAP.

Also, I know Vote #1 made it, but I gave a chance to vote #2 halfway through the battle to make it a little more interesting. :p

Anyway, I hope you enjoyed this story, and the bonus chapter will come someday. Be sure to check out my other stories as well. Stay Fresh! ;)
