1. Tira (Soul Calibur III)
I should begin by noting that my favourite Soul Calibur lady always has and always will be Sophitia because as contradictory as it may be in a Top Five of deadly, bad-ass babes, her goddess-like image does it for me. The third Soul Calibur introduced a few new female characters to challenge the established sex appeal however and one of these was the manical Tira, a very Harley Quinn-esque character with a massive razor ring weapon and unique multi-stance fighting style. She's a real nutcase who enjoys killing but is also quite childlike and hyperactive which contrasts starkly with her violent streak. Tira's original appearance included an odd blue-coloured hair-do that was most certainly out of place in a game set in the fifteenth century but later renditions of the character were more suitably garbed. Thankfully, she remained just as mental as ever in SCIV and V and even gained a soul-sucking kiss of death super death in IV. Perhaps we can see those sexy green rags one more time in the future as a 2P outfit though, Namco?
