Ghost (Wario Land: Super Mario Land 3)

Zenisukii was a member of the Black Sugar Pirates and was a giant Ghost Goom. Zenisukii appeared in Super Mario Land 3: Wario Land and Wario Land II in Parsley Woods, serving as the penultimate boss in both games. Zenisukii could paralyze Wario and was immune to body slams, coins, and fire. Zenisukii also turned invisible dropped coins that transformed into Ghost Gooms to attack Wario. Wario defeated Zenisukii by tossing his Ghost Goom minions at him.

Trivia

 * Zenisukii's name was derived from kozeni (coins) and suki (like), literally meaning "to like coins."
 * Zenisukii's name was revealed in volume 11 of Super Mario-Kun.
 * Zenisukii and Bobo were the only crewmembers besides Captain Syrup who appear in Wario Land and Wario Land II. Both of them seemed to be of higher rank than the average member: Bobo was the guard of the S.S. Teacup and Zenisukii was the penultimate boss.
