I - It's the most impressive, almost like a leader or a superior. I can see few of them, being the best. A guy like this sounds strong enough to weild an hammer, or something with spikes. And maybe some special powers consisting on pure strenght. And very tall and bull.You must be registered for see images
IV - This guy sounds very strong aswell. Like a mercenary. It feels strong but very agile. I can see him be a very pain in the ass, very quick. I can see him weilding 2 blades, being stylish swords or maybe hooks, for quick and deadly blows. Thin and meddium stature
III - this guy is the most petit, and I can't see him in short-range. So I'd probably give him an archer rank. he'd stick on the back, and on higher positions holding a bow. I don't like easy villions, so i'd made him the best archer possible. Precise, deaddly, maybe with the ability to shoot more then 1 arrow per once. Short and thin.
II - So this guy should be the minnion. But again, i don't like weak guys. I could see him with a sword or chains with hooks to rip the opponent. I'd give him a Fit look and meddium stature. This guy could be strong but not as strong as I, agile but not as agile as IV, maybe a nice combination of the two.
