I am adding robo mike this time, since im bored as shit. Here are some things (no custom movesets will be shown here, he has some but no spoilers.)
Robo Mike will be a lot floatier. He can jump higher than Mike & Boss and it takes him a bit longer to get down to the ground.
He will also not be able to collect any sort of powerups, meaning he can't get Fire Flowers or Purple Flowers (yes, he cant collect purple flowers.) I will make workarounds to this to make the game playable.
(p.s; Robo Mike will be heavily air based and most of his custom moveset will be based on his air movement, unlike boss.)
Took long enough as I wasn't even sure to add this guy due to the complaints from everybody, most of which were actually kind of off, but still I've decided to add him to the leaderboards.
