Mister Magic Pierrot was a Lemures sent by PallaPalla to assassinate the Amazon Trio. He attacked by throwing a handful of spades at the Trio, but one of them instead struck Usagi Tsukino's Dream Mirror and shattered it. Another spade struck and killed Hawk's Eye. The remaining two of the Trio decided to give up their power and use it to restore Usagi's Dream Mirror. Once reawakened, Usagi transformed into Super Sailor Moon and destroyed the Lemures with Moon Gorgeous Meditation. (Source: Project WikiMoon)
