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.
