Kunzite

Malachite is the fourth and strongest of Queen Beryl's generals in the anime Sailor Moon. In the manga and the Japanese version his name was Kunzite. Voiced by Dennis Akayama in the English anime.

Malachite is even stronger than Queen Beryl herself, but despite this, he remains loyal to her even after she kills his love, Zoycite.

First appearances
Malachite first appeared in Episode 18. He was later seen occasionally, but actually attacked the Sailor Scouts in Episode 29, trapping them inside a black dome and weakening them in an attempt to force Tuxedo Mask to hand over his crystals, but Sailor Venus arrived and shot Malachite's hands with a Venus Crescent Beam smash, destroying the forcefield.

In Episode 30, Malachite appeared as part of Zoycite's double-cross, when she challenged Tuxedo Mask to a battle over the crystals, he appeared and took them. In Episode 31, he witnessed Queen Beryl kill Zoycite. However, the only one he seemed to feel animosity toward over Zoycite's death was Sailor Moon, and he attacked the Sailor Scouts later on, but Sailor Moon fought him off using Cosmic Moon Power.

Evil plans
As it was Sailor Moon / Serena who possessed the Imperium Silver Crystal, Malachite's plans revolved around trying to find and destroy Sailor Moon and take the crystal from her. However, he often got into arguments with Darien, whom Beryl had turned evil (though he still fought off Malachite's monsters at times). Like Zoycite, Malachite would turn people into monsters, except they can disguise themselves as their human forms at any time.

Malachite's monsters included Mitsuaami, Polite Society, Blizzard, Misha and Janelle (whose original names are the same), and Ninjana. At one point he summoned the Ancient Creature of the Lake. But all of these monsters were healed by Sailor Moon.

Death
In Episode 39, Malachite attacked the Sailor Scouts in a cave, but they were sent back in time to view the battle at the Moon Kingdom. During this scene he was seen in a flashback, standing alongside Jedite, Neflite, and Zoycite. In the present, Malachite attacked Luna and Artemis in a snowy area, and nearly killed them. The Sailor Scouts fought Malachite, but he had the advantage, as he gets stronger whenever they see him, and threw powerful energy blades at him. But Sailor Moon gained the upper hand using Cosmic Moon Power. Malachite threw an energy blade at her, but she reflected it back at him with her crescent moon wand, mortally wounding him. Before dying, Malachite said he'd be coming to join Zoycite soon.
