Darien and Serena soon had to prove how strong their love was. Prince Diamond of The Nega Moon Family had fallen for Sailor Moon, but this obsession was soon defeated when The Wiseman betrayed The Nega Moon Family. He also tried to lie to her about her loved ones, but Sailor Moon didn't believe any of his lies about her loved ones especially Tuxedo Mask. Tuxedo Mask also called him on his lies and came for Sailor Moon when she needed him. He also fought Prince Diamond for Serena and had won.
(Credit to Victoria Rose (Aka Blue) Onyx, the Homeworld General turned Crystal Gem, turned Homeworld General again after they betrayed her... or did they? Her weapon is a greatsword, and she can create synthetic black crystals to use for a multitude of purposes. She may be a "Homeworld Gem", but maybe someone can get to her, and change her for the better... Now a member of the "Blue Group!"
