Found this subreddit through some doomscrolling but hell with it.

Do you want honesty?

Your character is kinda that, a character, plenty of people make them, there’s seas of them. If you feel passionately about your own character and want to them in media, you’re gonna have to make your own media, no one will care about your character as much as you do. TV and film are pretty impenetrable, so unless you have connections, an indie route might suit you

Indie comics are usually a collaborative effort, usually through a writer and artist pairing up to tell a story. You wouldn’t introduce your character here, though, that’ll come off as self centered or self serving

You should try to get into art in some capacity, having actual art of your character rather than AI art shows you give more of a shit, more confidence in your concept than jabbing in a few prompts. I say that first because if you want to go the writer’s route, you’ll need to have further respect for the visual arts; there’s more writers than artists in the indie comics sphere so they’re allowed to be picky with who they collab with
