I have hundreds of different characters ive made as I enjoy working on a few narratives
Alot of ocs you come across nowadays are either strong for no reason, basic in design, personalty, or backstory, they have no hobbies (always saying "I'm bored"), and yeah, as you mentioned, antagonistic for no reason sometimes
I also feel like an oc that has an atmosphere and purpose is one worth investing time into
i love making ocs based on things like mythical creatures, objects, and plants and such
but the main story im working on revolves around superhumans on a futuristic earth dealing with conflicts like alien overlords and such so i have a fair share of those too
srry for yapfest lol
