When creating a new character, do you usually plan their personality, backstory, or design first? Do you see any correlation between what you plan first and how well the character sticks in the long run?
I tend to do a mix of both? Sometimes there's a lot of pre-planning, other times I just draw someone up at random or with a vague prompt and go from there. I do think the characters I plan out more tend to last longer? I think when you just spontaneously create a character, its more of a visual connection generally, rather than something deeper. Not always, though, since I've definitely got spontaneous OCs I've kept around a long time!
