The Rib Tickling Hero, Sans! (Undertale x My Hero Academia Crossover)

Chapter 8: Battle....START!

Sans sits with Frisk and Chara, not saying much of anything. He already knew he would be out okay...but one outlier could ruin this entire plan...he needed to chat with a certain "demon."

"...Chara...you know what not to do.." he says.

Chara was a bit taken aback, but defiantly folds her arms "and that is..?"

"Not to kill anyone, or hurt anyone if you don't have too.." he says "you of all people should know that once you kill in this world without justifiable reason, you'll be marked as mentally unstable...I could care less about what you do, but if it involves frisk and my new friends...don't even try it." He says.

Chara sighs and acts like as if this wasn't some sort of important thing. "Yeah yeah yeah, like I haven't already heard that from frisk, and.."

"What? Do you really play me for a fool? The constant resets and begging of frisk to let us live..? That wasn't important enough either?!" He says. "Look...you either play nice, or you can dance with not only me, but the entire world of heroes here..hell, possibly even villains if they see you as a threat as well.." he says. "So now that I told you your boundaries, don't fucking cross them." He says.

Chara sighs and looks down, for the first time, she felt defeated. "Fine...whatever smiley trash bag..." she groans.

The intercom crackled to life. "Young teams! The test will begin....Now!" A heroic voice called out.

Sans sighs and gets up, walking off towards the building. "The plan is simple. I go on ahead and distract whatever threat faces me...you and frisk run in ahead, and find the bomb. Using frisks ability to dodge the others attacks, and Charas relentless barrage of attacks, you claim the bomb, and we win. Don't try to hurt anyone else if we claim the bomb, got it, Chara?" He says.

Chara nods and folds her arms "I'm not an idiot you know...unlike you." She says.

"Yeah...I'm an idiot..." he walks inside the building "the best you can do is hang back and hide around corners of halls i've already passed..." he says. "That way the person I face would assume you were either too far away to get into our fight or already ahead.." he says "depends on how stupid the enemy reacts." He says.
———————————————————————
Sans walks into the building nonchalantly, not hearing any footsteps as of yet. Hmmm...frisks feet were always silent...I guess she would be perfect for stealth and reconnaissance in this world... he thinks to himself as he walks forward a bit more, trying to stay as silent as possible. The air was still and quiet...too quiet...unnaturally so, like he was back in his old Judgement Hall. It sent shivers down his spine, but he shrugs it off.

By the time he readjusts, however, he saw a red haired kid running at him. He sighs and dodges out of the way. "Ah...Kirishima!" He says "how's the manliest man I know doing, eh? See your keeping up your rock hard body up, eh?"

Kirishima, genuinely confused, cocks his head "are you gonna..pun me to death..?"

"Well, to death, nah....but...maybe till your head hurts." He says. He hears footsteps head of him. Good...frisk and Chara are ahead...time to have a bit of fun playing catch the skeleton with hard head here... he smiles.

As Kirishima runs at him, and slaps at him. He opened his eyes to see sans is gone. He twists his head to a yawning sans "eh...this game of tags fun.." he chuckled.

Kirishima grunts "that's not manly at all!" He says

"Actually, it is.." he says "most villains use brute force tactics...I've learnt that from experience." He winks "also...I'm not all that durable..so I wanna last..." he smiles "but I can't dodge forever...I promise ya that much.."

Kirishima yells as this game of tag between him and sans begins they're brawl. (If you can call sans just dodging every now and then a brawl...)
—————————
Frisk runs quietly around the halls, her footsteps echoing ever so slightly. Chara just nonchalantly floats with her, sighing to herself. "....why won't he understand that I don't feel the urge to destroy this timeline..." she sighs "..doesn't he know that this is all new...?" She says "doesn't he realize your little "reset" only affects you..?"

Frisk hushes her before turning a corner, before nearly being hit by a wall of sound. She dodged and hides behind a pillar, covering her ears.

It was Jiro, now taking her earplugs out of her boots. "Clever of sans to send someone to deal with me while he handles Kirishima..." she smiles, and gains a determined look "but I won't give up so-"

Chara yawns as a red knife shoots up from the ground, nearly hitting Jiro. "Quit with the monologue and lets just get this over with..." Chara says.

"C-Chara you nearly..." frisk says, a bit scared

"Relax, you....unlike previous times, I've learned to control my damage output...he'll, they can be fully impaled and only take a small scratch if I wish it.." she smiles "now....hold still"

Jiro grimaces as she shoots sound waves toward Chara, which seemingly don't affect her.

"Could you stop with that?! Your firing sound at a ghost....a ghost." She says "I can't feel physical pain.." she turns to frisk "when you see an opening...run to the bomb.." she whispers as she fires more knives at Jiro. Jiro, however, wasn't stupid. She Shot sound waves at Frisks pillar every now and then, making sure Chara's little distraction won't cause they're failure

"You May have a soundproof plan..." (sans laughs silently down the hall) "...but I won't fall for this game! I'll beat you with the clock!"

And thus, another battle, filled with attacks and dodging, continues.
