Oh gosh, it was probably InuYasha? After that it was Fullmetal Alchemist and Naruto.
I wrote some pretty cringe-worthy fanfics at the age of 12. But you know what, it's all good because I was having a great time.

Honorable mention is Final Fantasy Crystal Chronicles. This was less of an online fandom, but I used to have dreams about my selkie character Miriali as a kid, and I did write a fanfic I posted online as a kid? She was illiterate and her love interest a Clavat boy from another caravan was teaching her how to read and write.

Uuuuuhh... Neopets? I suppose that counts as a fandom. I used to draw artwork of my pets all the time.

[ninjashira]

Oh my gosh, now I'm definitely going to have to go back and re-read Errant through the lens of Slayers Influence

[VibrantFox]

another sonic fan lol

I didn't do a lot of the making fanart or roleplay back then (did rp more with irl friends than online folk) tho the fanart bit's flipped on its head now I was mostly an observer watching the anime, looking at cutscene compilations, amvs, fanart, fanfics and I think the most I ever made myself was this sort of au fanfic series that was either it's own parallel universe like the sol dimension or set in the future post sonic but pre silver

it 10% was an influence for me from worldbuilding to character development, half the cast are what fuiled my semi-obsession with in depth character analysis and i dunno whether thats a good or bad thing still very much a part of it now tho lol i think ol blue is the one hyperfixation i'm unlikely to shake

lol way back in the late 90's-early 2000's my friends and I were really into Sailor Moon and Dragon Ball Z, cuz back then that was pretty much the only anime easily accessible at the time. We used to make Geocities fanart websites and share them with other classmates.

These aren't mine, but this is the kind of stuff we used to do, complete with missing images and horrible layouts, lol.

[Berserker]

I was pretty big into Berserk. I mean look at my name heh. I created a mod for it in the game Mount & Blade.

[sorible]

wow this image gave me so much nostalgia. I can't believe I used to go on sites that had such bad design like this

[Tailzkip]

As a 90's kid, I was into the Danny Phantom fandom at first online lol. I was allowed to roam Deviant art at 14...The internet was on simpler times and adults didn't know how computers worked lol. I was a good kid though, so I stayed away from the...horny jail side of stuff.
Edit: here I dug out some old ass fanart from my DA lol from 2012....so I was 11 turning 12

*coughs

Um, freakin Catz hexxing, anyone?

The Catz community was HOPPIN back in the day (and strangely had some weird drama) but I was too wee babe to code anything so I just watched

I can't find pictures on my computer anymore but at one point I was managing like 30 of these ugly catlike computer tomagachis and loved them like they were not a stupid computer tomagachi.

[chestnutriceeee]

Pokemon. There was a lot of pokemon in my childhood

[azzy-m]

Oh geez, I really don't remember. I think it was the PJO fandom - that was the first time i really actively engaged in a fandom/community, so.

[LunarScyphozoa]

My first fandom was Odin Sphere

[MeltingCORE]

Code Lyoko and InvaderZIM 🥺

[Kelheor]

I don't think I actually ever was in a fandom? Like I never really drew a lot of fanarts or write fanfiction or wanted to bond with people over a cartoon
But there is a fandom important for me. Just a couple of months before I first got on the internet I was reading Loveless manga and somehow after a few hours of browsing I found a Loveless rp forum... and I kinda stayed there for 6 years Can't really say I was into Loveless a lot, but what happened happened, I got myself a canonical role, bonded with a lot of people on that forum, wrote some working rules of the universe magic, etc, etc, and this alter-ego is kinda still with me and I treasure it a lot.

[djourner]

I'm pretty sure i'm the standard
Weeb/RPG nerd/Furry in that order.

I was never a fandom type of guy, so my participation in any one thing was really modest up until I found the furry fandom at the ripe young age of 22 xD

The most unusual thing about me is that I have been following a hecktoon of webcomics and indepent artists before I joined the fandom... I have a folder on my browser with over 50 links to webcomics that I still follow to this day.
And that is because I purged some of the REAAAAAALY old and non-update ones anymore.

[artamazon]

lol, its all we had!

[Oto_Kouda]

Artix Entertainment.

It's a company that would (and still does) make these little flash games called AdventureQuest, DragonFable, etc., and I used to play ALL their games. Their games are all on a single timeline, and little me LOVED that!

[noenoh]

ok since I was beginning u when the internet (LAN) was getting accesible to ppl here... I didnt heard the word fandom till a lot of years later....
so when I was finally getting on the net I was very deep on Yami no Matsuei (still am), Eatman, FF6 and 7 and Evangelion

the first anime I could say I was really in as in a fandom was Death Note (I even was a mod for a big spaniard forum back in taht time lol)

[rachurch95]

Oh snap i still play their stuff actually!!

[rachurch95]

Goodness neopets... i remember playing destructo match so much
