There's also that other Yoshi like thing that actually is trans, I forget her name though, the pink one that looks like she's half way through saying "HOOPLAH!!"
She's canonically trans in the Japanese version of the game, she gets picked on for it. There's also someone in paper Mario who's also trans I think, and this time she's on your side.
Trans nintendo characters:
Yoshi: Can lay eggs, is he/him, probably trans.
Birdo: Trans in the Japanese version.
Vivian: trans in the Japanese version, also a witch.
Samus: Jury is out on this one but probably trans.
Shiek: not trans (?) but definitely an ally
You, the player: Possibly trans but definitely valid
Link: This elf is enby and there's nothing you can do about it.
Luigi: I can't find proof but yes they are.
@Ivafakename Kirby is the eldrich abomination spawn that we want to see in the world
@Ivafakename no i literally mean it, apparently according to the lore he's the child of an ex god of destruction, but instead of wanting to destroy everything, he's actually just, really nice and sweet, and good, and just wants everyone to have a good, nice, safe time.
@Ivafakename I haven't even played a lot of the more recent Kirby games but... apparently yeah a whole truckload of lore was dropped and... WOW IT'S HEAVY SHIT.
@Nine Kirby either is god or could kill god, and frankly, I don't care if there's a difference
@Nine I. I don't know if I should just believe that or not, but... I want to...
