Alright, it's time for a mascot DEATH BATTLE
Sonic VS Mega Man (Sega VS Capcom)

Sonic The Hedgehog has a lot of matchups that's just waiting to happen
Mega Man is already a great option for Sonic
they've already done crossovers, they're both blue heroes

Both villains of the franchises are scientists and make robots
Sonic is faster (of course), but like Mario, Mega Man has a lot of abilities taken from the robot masters
Tho as fun it could be to see a remake of Wily VS Eggman
I'd still love to see this become an episode
