I still remember back when I was like...12? 13? I made a lot of very unfunny comics that ripped of anything I saw on iFunny or Know your meme, after that I tried doing some more OC oriented stuff with a comic called "Cheap Quest" but that quickly got abandoned. I ended up reusing some of the character designs in that one, for example Dorothy-Ann became Anne-Marie and a sassy blue haired character became the main inspiration for WSL-B
Before that I would doodle on stuff like the 3DS drawing thing, with the letters, and create Walfas comics that I never actually posted because I had no idea screenshots existed. (I was like 5 ~ 7 I think during that time) In middle school I also tried to make a comic, with the same characters I "made" in walfas
In that one my favorite OC, Gelatina originated. That comic was actually physical and I still have it...but honestly it's so bad that I'm not sure if I ever want to share it.
Other than that...I had made OCs in games where you could create custom characters such as DQ9 and then doodled them (very poorly) but other than that I think that's it? There are vague memories of a devil boy and angel girl that I used to draw bunch but idk if those even count as I probably just gained sentience around that time
