What I mean by this is did you come up with a name then fit a personality to it, or a personality fit to a name?What about physical features? What was the very first thing that made you think "I want to make a character like that"?
My characters so far (and one I am making):
Lex: I needed a character that wasn't very powerful to basically suffer under another character concept, Vlad
Vlad: I made an unpublished map with a unique game in it with lethal consequences for it, and I needed a host. Obviously a host for a game like that would have to be somewhat psychologically unstable.
Jerry: Didn't last very long. I wanted a character with an acidic cynicism that would get on every other character's nerves.
Spitfire: From a book that I hope to eventually write. I have the basic idea what I want to do with it. This was a personality-first development originally based on the song Spitfire by The Prodigy. Over time, the character deviated a lot from the song, so there is little resemblance now.
Roger: First character I ever played. Made the body then just made it all up as I went along.
Lucious: Second character I made. I wanted to play a fox that matched the lore/archetype.
Narrator/Tester: Not even a character, I just sometimes wanted to be me without constantly using (()) or []. Also, sometimes if I used my other characters to test for tech issues, people tried to RP with me. And I do hope to eventually GM a story without actually being in it, and actually have a system for combat.
Marquis: I started personality first. He is a psychic, but doesn't really gain any valuable information from it. Basically, he dreams a dream based on a mind other than his own. Even this he can't do if he is actively invited into their minds. Body and name are a loose fit that just seemed right.
Nightmare: I was listening to some Rob Zombie music, and I wanted a character that looked scary in that way. So physical features first.
Karl: Honestly, I don't even remember.
Karn: personality first (gentle giant, halfway in between the butler and monk archetypes)
Doran: My excuse to play a Vorlan like character, cause cryptic stuff is cool. So personality first.
Raiden: The name sounds really cool, and it is the name of 3 videogame characters that I know of and 1 series that I play. So I looked up the name (god of thunder) and now developing the personality.
