Hwoarang is actually probably Yun-Seong's descendant. :P He has a nice balance of strength and speed and he has a few kicks that make for nice combos. He's the only character with any real focus on kicks, actually. Give him a try.

You should really mess around with everyone, though, just to get a feel for them, then pick someone you like. Soul Calibur plays pretty differently from games like Tekken. It's not so much about combos as it is about mind games. :P
