I think I can top these...
My epic level FR meets Call of Cthulhu campaign had party members up to, and including,
Thalias Darkshine, a formerly elven rogue who thought he was a fighter. Specifically, he thought he was Drizzt Do'Urden. I say formerly because he was turned into a cat-person by an ancient artifact.
Logain, a half-orc barbarian who liked messing around with the multiverse. Before he died, he had started a revolution in Hell, was turning into a half iron golem, and had been possessed by a demonic pikachu (yes, the campaign was slightly silly, wasn't it?)
Kat`e, a half-deep one Cleric of Tymora with severe paranoia about her Umberlee-worshipping pirate family.
Klattu, a half-drow cansin alienist with delusions of grandeur. He was nuttier than a pecan orchard, but he was very good at blowing stuff up and summoning eldritch entities.
Jorn Talronse, a fallen lupinal in the service of Baalzebuul.
Jin "And Tonic" Telvrani, a wild elf arcane archer who hit on anything with breasts and drank enough to kill lesser men. Er, elves.
P'sharr, a hideous abberation (homebrewed) rogue/assassin/ninja. He could walk between raindrops, kill a man twenty-three different ways with his bare hands and align the chi of any room. His cover identity was a wealthy newspaper publisher named Kane.
"Foxfire" a kitsune pyromaniac druid with an entire solar-system worth of backstory she never bothered to tell anyone and a brother who just wouldn't stop getting himself killed.
Is that strange enough?
Demiurge out.
