I must admit, when I first saw Karsh I'd gotten the impression that he would be a borderline bishie, what with the hair color and his flamboyant sense of fashion, but I was delightfully proved wrong. He's a jerk, occasionally an asshole, mean and I love every second of it. I actually prefer him to Glenn if I need a green on my team, especially considering his stats; he's got great hit points, wonderful strength and toughness,and his magic isn't all that bad. Very much a rgeat choice when it comes to playability.
My absolute favorite is Grobyc, though. I had him on my team just about as soon as I got him, and repeatedly kicked ass. Gotta love the arm, and with how he shoots it reminds me of Robo, though Robo has never looked as cool. Considering he's very much melee-based, I think he's awesome, as he's even got some decent magic stats. He's got nothing that stands out as a real weakness, and his apathy and use of logic has always been food for comedic thought. It's always the hard and stern ones that take the most crap from the fandom, anyway. :3
Though, at first I liked him mostly because his hair was spectacular, and I wanted to keep him around just for the cool factor. Turns out he was a lot more useful than that.
