syro crash and sonic, waluigi, not toad because what could his moves be?
Crash... Spyro. These characters are not the same as Sonic. Sega created sonic and Nintendo works with the company and has contracts. Crash comes from a competing industry. i think Mega Man might be a need character, but might be very similar to Samus. There would have to be some thought put into his moves before he could be a made into a character.
