I still believe in Leopaldon and Fanny
This game has one joke character, Fanny would be a perfect inclusion for more comic relief, and Leopaldon could be their chance to make a heavyweight done right
You can scale them down and make some shit up, like "the gear body was destroyed or couldnt handle any more damage so they had to swap for the body of the gear offspring"
The fact it's fucking Leopaldon, a character almost no one even knows exists is the perfect excuse for them to just make something up
Now that Lucy is coming i don't see a reason for characters to be bound by lore, at this point just throw Kliff or Judgement or Izuna into the game
You could make a season of just Jam, Kum, Answer, Raven but that would honestly be kind of boring, these should have been in the game since day 1
