Zero

Zero is the masked hero of El Desert Land. She is a rather experienced swordswoman, and, although known as an outlaw, she is only labeled so because of El Koopitan being the "law" force. Zero only appears in a The Super Mario Bros. Super Show! episode "The Mark of Zero / Toupee". She is a parody of Zorro, and looks similar to him. She marks all of her enemies with her signature "0" mark, another trait she shares with Zorro (his "Z"). At first everyone thought that Zero was a man; however, the end of the episode reveals that Zero is female and that she sells food.

In the episode she is kidnapped by El Koopitan and the Koopa Pack, consisting of several Koopa Troopas, led by Mouser. The town of El Desert Land is not safe without her, so Mario and Luigi dress up as Zero and go save Zero from El Koopitan. She is saved from El Koopitan and El Koopitan runs out of town at the end of the episode.
