>>48325287>GeneralBuff their teams in general. I recall people pointing out that one of Tierno's Pokemon (Rosarade, I think) only had a single move, said move being a dance move.
I'm not sure if Shauna has enough of a gimmick to center a team around, plus she seems to have had the most effort put into her, so I'll focus on the boys.
>TiernoTierno needed to be in a game that actually has contests or something similar so that his gimmick of wanting his Pokemon to dance could actually be used in some meaningful way. As is, make his later fights either have him use tankier Pokemon or just generally theme each pokemon around the dance they do (Give him a water type and throw a rain dance on it). His Corpfish and Talonflame kinda do so already, but lean into it more.
Also, I think Tierno comes off as the least developed of the three. Do we even know where he lives? So that's another issue.
>TrevorThe first and obvious thing: The issue with his parents (i.e. his entire motivation for going on the journey) leaving him and his siblings. In the final game, you only ever learn about it by stumbling into his house in Lumiose and since it's just an NPC conversation, he never actually talks about it so it's just kinda there.
The second obvious thing: Have him challenge the player on completing the Pokedex more often: Either have him give the player an item for having more Pokemon in the dex than him, or (the path of less resistence) do the Blue/Lategame Wally thing and have him always win until a certain threshold where the player effectively overtakes him.
