Pink hair, wide hips, and cutoffs; that describes my perfect woman. The riding crop is pure bonus. Poison made her debut in Final Fight, showed up again in Street Fighter III, and has been missing from my life ever since. Her appearance in Street Fighter X Tekken is a dream come true, and the addition of Yoshimitsu on the Tekken side of things only makes it that much better.
As for Dhalsim and Steve, meh.
