SANS MEETS MHA

Haha so I was reading a comment of a sans meets MHA and they said they wanted to see a skeleton sans meet MHA so being the dumbass I am, Iam TRYING to do this! It is kinda the same as all of the others but at the same time not...? Please correct on every single thing EXCEPT my AU. Yes yes it isn't OG Sans as I can not do his canon personality better than some.
Summary-

The obscured wound on the skeletal figure deepened out from beyond their body. A substance that looked similar to blood started making its way onto his dirty white shirt and bright blue jacket. His sockets widened if possible as the human child before him smiled.
"You are a stupid fuck Sans." The child spat with venom blood splattered on their yellow-ish tinted skin. Their eyes red, glowing, and evil, gleamed against the dark area they were in. " I told you not to fight! AND WHAT DO YOU DO?! FIGHT ME!" The human yelled as skeleton's fragile body started the melting process of dusting meaning he was almost gone.
" H-hah..." The skeleton coughed up more of the blood like substance seemingly laughing at the villain before him. " I-I was a-always an as-asshole huh k-kid?" The skeleton grinned his sockets lazily dropping down to a half-lidded look. The child grunted in annoyance.
"You know what? I think I'll do this route ONE MORE TIME!" They screamed happily knowing this would upset the skeleton. The human's joy was increased as the skeleton fell to the ground yelling for the mercy they so deserved. As a final grin grew on the human's face the RESET button was pressed. Sans, the skeleton, fell...That didn't happen before....Was this something new that Sans had been craving...? Maybe... Sans relaxed not even feeling the ground collide with his body....
