Sometimes I’ve looked at some rules interaction that looks fun, then build a character around that.
Other times I have a concept for a certain type of character (aesthetics, personality and/or archetype) and from there look for mechanics that can help realise that vision.
Yet other times I have a backstory in mind and that story and the setting drives the game mechanics choices.
It depends!
