My very first character, I remember him well (though not his name). I got introduced to roleplaying through a Hongkong Action Theatre game. Game got forgotten very fast. About 10 minutes into the session after my character 's first action, the DM exclaimed: "you've ruined my game, you did something I had not planned for"
My second was a superhero (actualy I rolled a stupendous character which turned out to be a god) but also got forgotten very fast. (hint: DM was same as for char one)
My third was another forgotten case, a WFRP character. This game got booted because... (nope, DM was somebody else but the rest of the folks were from that same group as one and two)
My first proper character was Reinhold Gottesfrieden, a judicial champion who would become the chosen of Sigmar in the "Enemy behind the Throne" campaign (WFRP).
My first DnD2e Character was Ishkla Waterbirch, a wood-elf wizard-thief who roamed the world seeking the killers of his tribe (he and his twin sister were the sole survivors until the sister got eaten by warhounds [her own stupid fault for falling out that tree, what was she doing in that tree in the first place])
