Likely mlp or fnaf :3

I don't fully remember which fandoms was I in first, but it's probably Hetalia...

Probably warrior cats or the furry fandom.. they go hand in hand

Pokémon and Naruto I think

Well first fandom I got into technically was How To Train Your Dragon, but if you’re talking making actual stuff for like artwork and so on then I gotta say Skylanders. Skylanders is very closely lumped with Spyro, Crash, Sly Cooper and etc games for me since I’d mix them together for obvious reasons.

vocaloid i'm pretty sure.

I'm too ashamed to share the first one so, FNAF.

fnaf n pokemon...

its either FNAF ddlc or yandere simulator I forgot

Undertale (?) Probably, I still interact with the fandom just not as often anymore.

FNAF!

five nights at freddys!!! i faintly remember in like 2016 i would beg my uncle to help me beat all the nights for the first game

what does it mean to be "in" a fandom? does it mean to just like a media property, or do you have to actively be involved in its community?

either way, probably Pokémon. I got into Mario first but was never that in depth of a fan
