Also Archie Sonic can be considered a brand new character since he is that according to Mario vs Sonic (2018) so that would make Flash the only returning character in this MU that's very likely the Archie Sonic vs Flash DBC that was said in.

Come to think of it, you may actually be right. Ben did say Sam was working on a returning character, and Sam showed a great deal of interest in this match. You just may be right.
