Characters you think will never come to the game

What characters do you guys think will never arrive in the game? For me, I think DJ Mary from Johto will never get added. She has a Meowth but she’s just a really minor character that I don’t see it ever happening.

For someone more important, I genuinely think if Trace doesn’t come this year I don’t think he ever will. Chase and Elaine don’t really get attention (Elaine’s the only protagonist in game with just one sync pair too). It just feels like if they were gonna add him it would’ve been before.
