I played with some guys who did the same thing with the npc's and pc's....
We fought Kristen Kreuk as a necromancer,
Some bondage guys based on Kirk, Spock, and McCoy...the Kirk had a ring of regeneration....not on a finger....and kept coming back
And the DM always made this one characters' combat senseis based on Patrick Stewart's character in Dune.
I played Sam L. Jackson, The Big Red-Headed Angus guy from Braveheart, a wizard based on Gilbert Godfried, and another wizard based on Dolomite the human tornado; he had to make all his spells rhyme.
