Okay, so...for ease of reference:
1. The aforementioned Rufus and Burne...
2. Elric of Melnibone (which I must admit is funnier when you leave the accent off the final "e")
3. Lightning zombies (D&D)...fabulous!
4. Wraeththu (from, well...Wraeththu)
5. Gotrek and Felix (WFRP)
6. Harlequin (Shadowrun)
7. Red Wizards of Thay and, specifically, Hazlik (Forgotten Realms)
8. Black Furies (Werewolf: the Apocalypse)
9. Jarlaxle (Forgotten Realms)
10. Johnny Rocket, Mutants & Masterminds (though he is actually gay in the setting - no implications needed!)
