The first character that I can remember right now (not really the 1st of all since play RPGs for a helluva long time), was an epic (and I don't mean just in level, but achievements) Dwarven Defender on good ol' D&D 3.5. That character was a wild ride but one that I enjoyed from start to finish of the game because of how much the RNG favored me on that campaign.

Here on the Guild, my first was poor Kotori Tsubasa, for Toybox Memories. I still remember that character fondly, even if she was also the first one of them to taste the reality that Forum RPs tend to never go anywhere. still, she was a good character, very rough around he edges, but good notheless.
