13. Sylvanas Windrunner (Warcraft series)
I haven't really played the RTS Warcraft games because I don't have the ability to multitask well enough to succeed in RTS games, but I have read the lore, and I've played a f***ton of World of Warcraft, so I feel qualified in putting Sylvanas this high on my list. First off, she's smokin' hot. Seriously, just like everyone is furry for Krystal, everyone is necro for Sylvanas. And not only is she physically hot, but this woman is the leader of an entire race of people who are far inferior to her in appearance (save for her dark rangers), thus making her a Queen HBIC, which is such a fun archetype. But really, my liking Sylvanas comes down to her backstory. She was the ranger general of the blood elves before Arthas began sending his undead legions to run roughshod over her people. Sylvanas fought valiantly, which pissed Arthas off, and as a result, he decided to f*** with her even after he killed her. He brought her back as an undead banshee to serve him, but she regained her free will and let's just say "Hell hath no fury". She made it her mission in life to destroy him, joining the Horde, claiming a city for her own undead legion and everything, and she fought the s*** outta him in Northrend, even when her own advisors rebelled, she took a brief respite from hating Arthas to reclaim her throne. Since then, she has gained even more allies (what with Arthas' undead legions having no master) and can make her own undead now...essentially putting her full circle in hating Arthas for what he did to her...and then doing it to other innocent people. That's what makes her so cool. She's clearly evil, even if she doesn't necessarily think so, and it's only a matter of time before she becomes the next big threat to Azeroth. Villainous chicks are always awesome.
