1. Garrus Vakarian (Mass Effect)
What is there to say about Garrus that hasn't been scrawled onto the back cover of a teenage girl's Trapper Keeper? The guy's a heartthrob, plain and simple. There's just something about him that makes women weak in the knees, and the mere utterance of his name brings panties flying in from every direction. His calm, soothing voice, his charming personality, his... sort of creepy, bug/kitty appearance... It's hard to figure out exactly what makes Garrus so damn appealing, but whatever "it" is, he has it.
As a squadmate in all three Mass Effect games, Garrus proves to be 100 percent loyal. He never questions Shepard's motives. He never flips out and throws a tantrum if he doesn't get his way. Even if you intentionally screw up his revenge plan, he walks away, totally cool about the situation. We're like, "Sorry we ruined your revenge," and he's all like "Whatever, you were right. Thanks for not letting me kill that guy. Let's go clubbing!" And then he's the designated driver, because he's THAT AWESOME.
Garrus wins our love by discharging pure charisma at all times. He's the kind of guy you'd abandon a family for. Women want to be with him and men want to be him. Hell, if your girlfriend told you she cheated on you with him, you'd ask for details before breaking down in tears, knowing that there's no chance you'd ever measure up to him when it comes to manliness.
