5. Garrus Vakarian

Oh, Garrus. The turian vigilante is a fan favorite from the original Mass Effect trilogy, and it’s easy to see why. He’s suave, his voice is sexy, and underneath it all, he’s kind of a doofus. His awkward attempts at romance with Shepard are genuinely funny scenes, even if his Mass Effect 2 romance is probably one of the weakest in the series in terms of writing. Mass Effect 3 more than redeems the rough start though, as this is a man who knows how to make a grand gesture, like flying you to an off-limits area of a space station to shoot bottles together.
Garrus would take care of you, and that’s his greatest strength as a hypothetical boyfriend. But in the midst of attending to your needs, he’d also be leaving every night to enact justice on criminals without any sort of oversight. One night he’s out taking shots with you at the bar, then the next he’s out taking shots with his sniper rifle on a nearby rooftop. He is the danger, and danger is sexy, but it does mean that you’ll always be wondering if he’s going to come home every night or if you’re about to get a call from C-Sec telling you something terrible has happened. He’ll get your heart racing when he does something romantic, then you’ll spend the rest of the evening on the verge of a heart attack as you wait for him to come back from fighting crime. Unless you’re a thrill seeker, your mileage may vary.
