Definitely Garrus cos he's level headed and yet can be brutal and ruthles

In Mass Effect I would probably say Liara she was so sexy in the intriguing way. Non - human romances for the win also. In Mass Effect 2 I was also attracted to the biotic chracaters for some weird reason Jack, Samara / Morinth ,

As for the guys I though Zaeed was an awesome old dude loved his accent. I just wished he head more lines.

I liked tali and miranda, wrex was also a good character to have around

Wrex is funny, but I like Garrus the best.

In Mass Effect 1 it is Werx
without doubt. In Mass Effect 2 it is hard to choose but it is Garrus Vakarian AKA Archangel,Thane Krios and Grant

Ashley and garrus

Garrus and Miranda

Definitely Garrus. I always chose him, both in ME 1 & 2. =)

Garrus in all 3 and Asheley was good as well

my number 1 would have to be Liara all the way...then Garrus or Jack
