Button Mash

Why we should add him
A youtuber made a fan video about this character called Buttonmash"s adventures, Buttonmash (or Button) Is a gamer that likes video games and cares less of his cutie mark, and the fandom makes buttonmash have a crush on Sweetie Belle, the animated youtube was cancelled by Hasbro but Buttonmash shows up in some episodes, and thats it. And we should add this Gaming Pony to the roster and he's a extra My Little Pony character along with Derpy Hooves and Starlight Glimmer.

Level 1:  He throws his JoyBoy at any oppenent and it'll electrocutes them if someone stands too close, and kills them.

Level 2:  He drinks a milkshake very quick in which causes him to have a brain freeze, and slows time down for 5 seconds and Buttonmash can one-hit kill any of the oppenents.

Level 3:  He blows a whistle and calls in a train to run over the oppenents, and its a cutscene, very simular to Parappa's, Toro's, and Heihachi's level 3 moves.

Rival
SInce he's a gamer, it should be any rival from 5 games and it should be a bit funny

Big Daddy

Reason: Buttonmash is walking till Big Daddy's little sis saws him and says to Big Daddy he wants to unzip him, because she thinks he is a stuff animal, and ButtonMash is furious and they begin Fighting.

Radec

Cole Macgrath

Reason: Button and Cole accidently bumped into each other and they get angry at each other, and cole sparks angrily while Buttonmash backs and gets into fighting stance.
