These are a few that I posted a while back on the
GURPS Repository site. They're rough in places, but I like the characters.
Mimsey Grant -- An amateur occultist and wizard-in-training for a contemporary supernatural/monster-hunting campaign
Major John Jeroboam Hunter -- A clockwork cyborg inspired by an Edgar Allan Poe story, for a steampunk campaign
Mitch "The Weasel" Weisel -- Originally created for an online game here on these boards; a low-level crook who took a job as test subject for a mad scientist and now looks like a ferret; for a pulp-era campaign.
Fenton Blake (Code Name: Flywheel) -- A nerdy gadgeteer for a secret spy agency in a '60s era espionage campaign.
Bonnie Baker ("Stinger") -- A teen sidekick to a super-hero named Avenger Bee, for a supers campaign
