Entourage - Ari Gold
You could argue that other Entourage characters - like movie star Vincent Chase - are baddies too, but the definite show stealer of Entourage has got to be Ari. By normal standards, I wouldn't necessarily call Ari physically hot (maybe I'm wrong), but his character certainly elevates him to that hot baddie level. His witty scathing remarks (does Ari ever lose an argument?) and general fearlessness to do whatever it takes to get his clients what they need is just undeniably...hot.
True Blood - Eric Northman
Why is Eric a hot baddie? Watch this clip. From the moment this guy made an appearance on True Blood, 2 things were very clear: 1) Eric is trouble. 2) Eric is smoking hot. Eric oozes confidence; vampires and people alike walk into Fangtasia and are drawn to Eric (as we overheard a guy's thoughts in one TB episode: "He's so powerful. He's so beautiful. Just walk up there and offer yourself to him!"). However, because Eric is such a big deal, he must summon you first if you wish to speak with him.
A fun tidbit: Eric is played by actor Alexander Skarsgard (son of Stellan), who was voted the sexiest man in Sweden 5 times!
Desperate Housewives - Edie Britt
When I'm a 40+ year old woman (which if you were wondering, I am not), I imagine that Edie is the sort of woman that I'll be jealous of. Edie Britt is the one that everyone is secretly jealous of...because for an "old" lady (I know, 40 isn't actually that old), Edie is still smoking hot. However, on Wisteria Lane, Edie is also a source of controversy and trouble. She's always on the outskirts of the inner-circle, because frankly, she can't be trusted. In Edie's defense, she is generally upfront about the fact that nothing or nobody comes before Edie Britt. She's arguably the strongest woman (mentally) on Wisteria Lane, which is pretty hot also.
Friday Night Lights - Tim Riggins
We love Tim Riggins (of Friday Night Lights, one of the Top 10 Shows You're Not Watching) because he's a baddie with a heart. Don't get us wrong...he's still a baddie, because spoiler alert he did sleep with his paralyzed best friend's girlfriend and regularly shows up at football practice/school drunk. However, Tim Riggins also does thoughtful things like protect the coach's daughter from making bad decisions at parties when drunk...at his own expense.
Dexter - Dexter Morgan
This one might be the most controversial, but to me, Dexter's style of vigilante justice (murder included) is pretty hot. I actually also find Michael C. Hall's character of Dexter to be reasonably adorable as well. Conclusion: I'd date Dexter. Am I deranged? Don't care.
