An Undertale Ninja Turtles Crossover

Chapter 5

"OH MY GOOOOOODDDDDD!!!" Chara screeched, "YOUGUYSAREREAL!!!!!"

Leo looked at Chara and sweatdrops.

"Um....what??" Leo replied confuzzled, "we're real?"

Chara covers her mouth containing her fan girl screams. But she bounced around and ran up to each one hugging them tightly.

Leo's POV:

What the shell?

Donnie's POV:

UUUUUMMMMM!?!?!?!

Raph's POV:

I HAVE BEEN TOUCHED!!!!

Mikey's POV:

GAH!!! DUDE!!! I'M A TERRIBLE NINJA NOT SEEING A GIRL HUG ME FROM BEHIND!!!! I mostly panicked and flipped her over my shell and took her down thinking it was an enemy, but then noticed it was just a girl with a green sweater and yellow stripes on.

"Woah!" I exclaimed, "sorry dudette.. didn't mean to flip ya.." I chuckled looking nervous.

"It's ok!!" The girl said with a grin on his.... Er... Her? Face.

Sans' POV:

After answering a few more answers from the press and news reporters, I teleported away to safety. Man, not a single monster lives here, except me and Asriel of course, but aside from that, no other monsters live here....

When I arrived in the front door, I noticed Asriel was uncomfortable being in front of Leo, the one in blue, (Y/n) having a staring contest with Donnie, the one in purple, Frisk poking Raph, the one on red, and Chara talking reeeeaaaalllllyyyy fast at Mikey, the one in orange.

Everything is normal and all... But I don't feel comfortable having Donnie to stare at (Y/n) like that... So I decided to go and be a dunkle.

"Alright lovebirds... I think that's enough staring.. " I said teleporting between them causing (Y/n) to snap back to reality and jumped.

Donnie blushes and looked away.

I gave him, 'the look' and took Asriel, Frisk, and (Y/n) to the stairs and went back to where Chara and Mikey were.

Seems like they're enjoying each other's company... But I don't want to ruin the cake we're going to make for the Megalomaniac... but for now...

Leo's POV:

I was talking with Donnie and Raph about telling this to Splinter. I averted my gaze to Sans who had a lazy smile on and pointed at me and my two brothers.

"Seems like Sans wants to talk to us." I said to my brothers.

"Wonder why..." Raph looks at Donnie.

"I didn't do anything!" Donnie replied defending himself.

We followed Sans behind towards a room at the end of the hallway. I suddenly feel uncomfortable being here, the atmosphere feels... Dark.. I looked at Sans and he stopped to turn around to face us.

"So, tell me," Sans began, "if I give you back you're so called green glowing ooze canister.."

"Mutagen actually," Donnie corrected.

Sans gave him a scare shell glare and continued speaking.

"I don't  c a r e." Sans replied darkly, "listen, if I give you this... Mutagen... You are to leave me and my family. Capiche?"

"But-" I began only to be interrupted.

"Don't worry, we'll forget this ever happened. Alright?" He said going back to his lazy self.

"And what if we don't huh?" Raph asked challenging him.

"Raph!" I whispered his to him, "what are you doing!?"

"What? I'm just saying," he replied, "he's a skeleton, he can't do anything. He's weak at his state!"

Sans just chuckled.

"Hey kid, don't judge a book by its cover..." Sans said with one closed eye.

Raph smirked. He likes challenges, cause he just took out his sais. "Is that a challenge bonehead?"

"Woah kid, look, I'm not here to fight. Just here to talk-" Raph didn't let Sans finish and runs towards him. Donnie and I tried to stop him, but he attacked Sans already.

What impressed me was that Sans dodged the attack with ease as if he wasn't even trying.

Raph kept attacking, while Sans kept dodging. Though somewhere in the back of my head, a voice rang.

He can't keep dodging forever...

I shook my head and looked at Donnie who was just watching the fight with a jaw drop.

This is the first time I have seen someone dodge attacks without even trying.

Sans then did something that I didn't quite catch. First, Raph and Sans were fighting, the next thing I knew Raph flew out of the room!

"What was that!?" Donnie cried as he helped Raph up.

"How the shell should I know!?" Raph replied back.

"Look, here's your canisters mutagen thing.." Sans said making the mutagen appear out of nowhere and tossed it to me which I caught.

I looked down at the mutagen to make sure it wasn't fake and looked back up.

Sans was pretty close up to my face..

As in really close...

He didn't have his usual white pinprick eyes instead it was just total blackness, like the abyss.

"Don't come back here. E v e r." Sans warned and then backs away, "heh, I'm sure you know where the exit is." He then teleported away like nothing happened.

I was speechless, my brothers were speechless, shell, I don't even know how we're going to forget about this!!

"So, the comedian took his game up a notch did he?"
