The Versus title for Wild Card shows a blank.
Wild Card is a hacked/removed character unlocked by a cheat in the arcade versions of the original Tekken. He had a name plate, but his picture is a rotating question mark (the same image as random). Wild Card has the appearance of Kazuya, and the moves of Yoshimitsu.
