I have to kindly disagree with you calling your old fanfiction stupid. You had fun creating it, and it gave rise to your original world eventually, so I don't think it's stupid at all.
I mean, both my comics are still technically fanfiction, one for Star Wars: the Old Republic, and the other for Jack Kirby's New Gods. Who knows, maybe one day I'll create an original piece too.
I just wanted to tell a story, partly out of spite at a segment of the fandom, and because I felt like my favorite characters in the game were dealt a short end of the stick. So that's kinda how Bestia's Wrath came to be. A culmination of, at the time of its inception (February or March of 2018), 5 years of developing my own takes on the characters.
As for my New Gods comic, I just had an idea for an origin story for my character, and that's kinda it.
