iron_liver -- Pretty much. Iron Man. Playing on alcoholism. I don't really love this username, but eh I am generally uncreative.

emperorshand -- Mara was the Emperor's assassin in Star Wars, and this name was pretty much playing...on that. It's so obvious. I also love this name and I've had it for too long.

deus_ex_100 -- SO HIPSTER. God in 100. Series is called Ex machina. Another one that I would love to change, but I am terrible at usernames for the most part!

elecdouble -- See Gabbie's Electro name. She's his double :')

pandablade -- In Warcraft 3, Illidan's warglaives have a panda face on the outside. I LIKE THIS BETTER THAN LIKE...the million of you're not prepared's I could have done.

megamaniacal -- Megamind...megalomaniacal... yeah. I actually really love this username!
