My favourite Gladiator was Panther. Her injury on Tilt was horrific though. She's got a gym round where I live but I'd be too shy to go haha.
I wish they would bring it back properly. The Sky series got so much wrong - silly costumes, not a great venue (I think the pool took up too much space), and the games didn't look right. Also, most of the Gladiators tried to be bad guys which just didn't work; in the original, only Wolf was the bad guy really while the others were all gracious in victory/defeat.
I really wish they could bring it back at the NIA. I think it would be a hit with the right set up. I wonder who could present it?!
