Mr. Magic Pierrot looked into Usagi's Dream Mirror after Hawk's Eye extracted it. Since he didn't find Pegasus, he then attacked the Amazon Trio, throwing spades at them. One of them hit Usagi's dream mirror and destroyed it, killing her. He then threw a spade at Fish Eye, but Hawk's Eye jumped in front of her and took the hit. Before dying, he shot a fire attack at Mr. Magic Pierrot, who blocked it with his hat. Tiger's Eye and Fish Eye attacked him, but he countered their attacks easily, turning Fish Eye's knives into butterflies and Tiger's Eye's whip into a snake. Tiger's Eye and Fish Eye gave up the power that made them human, destroying the orb, in order to rebuild Usagi's dream mirror. Usagi and Chibiusa transformed into Super Sailor Moon and Super Sailor Chibi Moon. Super Sailor Chibi Moon summoned Pegasus with Twinkle Yell, and Super Sailor Moon destroyed Mr. Magic Pierrot with Moon Gorgeous Meditation.
He was a clown who attacked by throwing spades from a party hat.
