The mysterious man fought alongside Nathan, helping him in a number of ways. Sometimes he would distract Nero so Nathan could land a hit on him, or Nathan would distract Nero so the man could attack. Sometimes he would toss a Splat Bomb to Nathan, as he would use his roller like a baseball bat to hit the bomb towards Nero like a baseball.

The young man showed great skill in the art of combat. He wielded two Hero Shots, or they could of been replicas, it was too hard to tell. Due to his armor being made of carbon fiber, he could move very easily. He was very smart too, he seemed to have lots of experience in combat.

"Damn!" said Nero, "You're fighting style is...quite well! But it won't be enough to take down this commander!"

"Is that so?" said the man as he unleashed a sucker punch at Nero's face, knocking him down. The armor gave the man greater strength. "THAT was just a tap. Now are you gonna give up, or do we need to crank it up to 11?"

"Maybe...After I turn your precious armor into a stained soup can!" Nero charged at the man, who evaded his attacks.

"Kid!"

"Right!" said Nathan as he rushed over. He swung his roller, flinging ink onto Nero's back. With Nero distracted, the mysterious man nailed him with a blow to the face.

"That's it! Time for you to know what the electric chair feels like!" Nero threw his electric wire at the man and it wrapped around his gauntlet. When Nero activated it, it made the entire armor suit's lights flash on and off for bit, but the man barely even flinched.

"Electricity cannot get past the gear underneath this armor!" he said, "The armor is made of carbon fiber, but the suit's inner layer is made of a material that cannot be electrified!" He grabbed the wire, throwing it aside as Nathan struck Nero from behind, knocking him down and making a small case that was connected to his belt snap off and fell to the ground, but Nero did not notice.

"DAMN YOU!" yelled Nero as he stood back up. "Forget this! I have a weapon to monitor! I'll deal with you next time!" Nero summoned an aircraft with a small remote, and using a grappling hook to get to the roof of a building. He jumped into the aircraft and flew away.

"Damn you Nero..." said Nathan.

"Are you alright?" said the mysterious man.

"Yeah, I'm fine! Thanks for your help."

"No problem, kid." He picked up the case that fell off of Nero's belt. "This may have something important in it. It came off of Nero's belt."

"Can I see it?"

"Yeah, here." The man handed the case to Nathan.

"Thanks. Who are you, anyway?"

"I go by many names, kid. A lot of people back from were I lived at for a while called me the Rogue Hero, but I prefer to be called 'Titan'. It's my nickname."

"Good to know. But...how did you get the armor?"

"I built it, with the help of a few others, of course. It took a long time to figure out the technology, but we managed to construct it."

"I see." Nathan opened the case to see something he wasn't expecting to see. "Wha-?! The third Boss Key? I guess I should've expected that though. The first place I'd expect it to be should've been in Nero's possession."

"I knew he had that thing, so I followed him. My original plan was to obtain it and give it to the New Squidbeak Splatoon, but I ended up not having to."

"How'd you know?"

"I've been spying on them for a while, kiddo. And I've...kinda been spying on your missions too...heh heh..."

"Why?"

"I'm trying to gather information for you guys, and I think I might know something about their Ultimate Weapon that they're building."

"You do?!"

"Yeah. I'll explain later...You know, I never thought they would return...Those suckers just don't know when the hell to quit!"

"You know about what happened two years ago?! But...no one but the Splatoon knew! How would YOU know?"

"...Let just say...I knew the captain well at the time. I haven't seen him in a long time."

"You know Cuttlefish?"

"Yeah...err...Kinda. I've met with him, and his granddaughters. But I never saw them very much."

"Okay...So are you gonna come back with us tomorrow or-"

"Nah. I'm gonna keep doing recon. Here, take this USB. I took some pictures and transferred it onto here." He gave Nathan a USB drive. "I'll be going now. I hope to meet again." He left and disappeared into the night.

"Huh...mysterious," Nathan thought to himself. He looked at the Boss Key and USB drive he had just obtained. "Well, tomorrow is another day." Nathan headed into his apartment. When he got to his door, he decided to check on Diana. He knocked on her door, this time without the knocker, and Diana opened the door.

"Ah, there you are!" she said, "What took you so long?"

"Octoling attack...again," Nathan answered.

"What?! Are you alright?!"

"Don't worry, Diana! I'm fine! A man who calls himself 'Titan' helped me. He gave me this USB with pictures he took on it, and we managed to claim the third Boss Key. He said he's been doing recon, and that this USB has images of the Ultimate Weapon the Octarians are building."

"Really?! Should we look at the pictures? I have a computer, and we can look at them and examine them before we show the others so we can answer any questions."

"Hmm...sure. It may be a good idea, anyway."

"Okay, I'll fire up the computer!" Diana turned on her laptop and opened up a photo software. "Just insert the USB in this port here. Any pictures on it will show up on the page." Nathan inserted the USB into the laptop, and three images and a video file showed up. They were too small to see what they were, so Diana clicked a yellow button on the screen, and the first image fulled the screen.

"What the-?!" said Nathan as he saw the image, a large construction site within a colossal dome. The Ultimate Weapon appeared to be an enormous Inkzooka/Killer Wail hybrid, but it was only half-finished, so it was difficult to tell what the weapon was truly meant to be.

"Whoa...it's like a mix between a Killer Wail and an Inkzooka. I...don't know to think! I have no idea what this weapon is supposed to actually be, or what it's supposed to do, but it looks lethal! And it's not even finished!"

"I know...but what I actually WANT to know is what it is. Turn to the next image."

"Okay." Diana clicked an arrow and the next image was revealed. It showed another image of the weapon, only more completed. It was now more like a giant Inkzooka with a giant Killer Wail at the end of it rather than an ink blaster.

"Okay...now I can see what it is. It appears to be a Killer Wail with an Inkzooka-like 'body'. I guess it's a mega version of the Killer Wail."

"Look at the corner right there! There's a door under heavy guard!"

"Huh...I guess that's Octavio's room."

"The door would've been a little more...fancy if it was Octavio's throne room, don't you think? I think it's something else. But why is it on such heavy guard?"

"I don't know." Diana turned to the third image to see a slightly blurry image of the door they were taking about. "...It looks like a door for a...tool area or warehouse? But why would it be on heavy guard?! It makes no sense!"

"Octarians are weird, but their must be a reason as to why that door's guarded...What does the video show?"

"Let's see." Diana played the video, which showed progress of the weapons construction sometime between when the first few images were taken. Both Octolings and mechanical arms placed parts into place, and multiple parts lay on the ground. Sometimes, more parts were brought in via aircraft from another door. But when parts were taken out, they entered the guarded door, after a brief inspection of both the parts and the craft.

"What in the-? Some of the aircraft carrying parts are going to that door instead! Why?" Nathan said.

"Maybe it's for the Octarian Airship?" Diana suggested, "To build other smaller ships and weapons?"

"Maybe...be that doesn't explain why it's guarded and why they inspect the aircraft and the part..." The video ended and Nathan removed the USB drive from the device once Diana prepared the computer for it. "This is getting weird...It makes no sense at all!"

"Well...at least we know what the Ultimate Weapon is!"

"Yeah...but still...Why the hell is that door on heavy guard?! It doesn't seem to have any purpose besides possible vehicle/weapon construction and/or part storage."

"I'll have to think about it..."

"Now's not the time to think. We need to get some shuteye, especially after a long day like today."

"Oh right! Pfft! Sleep!"

"You forgot about it?"

"Well I was looking at pictures with possibly essential information! I got excited!"

Nathan chuckled. "You crack me up, Diana. Well, I'll be going now."

"Okay. Good night!"

"Good night." Nathan closed to door behind him gently and entered his own room. He placed his roller by his bed so he would have quick access to it when he woke up in the morning. As he drifted into a slumber in his bed, he wondered if tomorrow could be his last day fighting Octarians. Whether that meant the final battle at last or his death at the hands of the Octarians, he was prepared for whatever tomorrow may bring.
