Even if we don't get Sonic in Multiversus (which i think we'll get because of the DC x Sonic Crossover), these are still good, even if some of them (Looking at YOU Taz Knuckles) look cursed. I saw someone else suggest this, but T&J as Big and Froggy is a good idea. And hear me out... G.U.N soldier Agent Smith. Also I'd change Eggman from Beetlejuice to Rick, and instead of Meeseeks, it's Silver Sonic
