Ka D'Argo is a character on Farscape, and my personal favorite Luxan warrior. Who else comes up with lines like "John, I gotta tell you something. I've never actually put this into words before. I love shooting things."?
D'argo is the B.A. Baracus to John Crichton's Murdock, the Charlie Houk to Aeryn's Riley. I've heard him compared to Star Trek's Worf, but he's really so much more. His crazy tongue attack and bizarre bleeding complications make him less human, and his history makes him so much less straight-laced and more complex a character than Worf. Can you tell I love Farscape?
Anyway, here's D'Argo, your character of the week.
