Mamoru Chiba, Xenian Flower
Unknown Alien species
Fiore searches for a flower worthy of Mamoru, and Mamoru forgets Fiore until he returns, with the Xenian Flower. Much to Usagi's dismay after simply being pushed down by Fiore himself, there was slight confusion between both him and Mamoru, leaving Usagi to wonder why Mamoru had never told her about Fiore. Fiore's jealousy of Mamoru and Usagi's friendship soon gets the better of him as he eventually attempts to kill the Sailor Senshi, especially Sailor Moon. After he accidentally injures Tuxedo Mask, meaning to aim his extended nails at Sailor Moon and stab her, he takes Tuxedo Mask to outer space for him to heal.
In the end, Sailor Moon shows him the flower from Mamoru is one that Usagi gave him that day, and he produces a flower from his life energy, giving it to Mamoru to revive Usagi and fulfill his promise.
