This variety of Noctvoir is widely believed to have been cursed once upon a time. Nobody knows why it has only one arm, but it does not seem to be held back by its lack of said appendage.

Umbvoir appear only at night, and are more common near full moons. Generally passive, these Pokémon light up their staves, rings, and horns to guide wayward travelers home safely, and create defensive walls of light in combat.

Despite their regal appearance, Glacevoir are extremely territorial, fighting off any potential rivals with freezing winds and psychic force. Their cruelty and beauty have led to Trainers in snowy regions referring to them as 'Chiller Queens'.

A wild Spirivoir harvests the souls of Ghost-types in hopes of breaking free of the Odd Keystone embedded in its chest. If it bonds with a strong Trainer, some theorize it will begin to feed off of their life force as well.

Darkvoir primarily shows itself at night to those with impure hearts, lulling them in with its innocent appearance before inflicting awful nightmares on them. It feeds off of their fear and anguish until dawn, then disappears until the next new moon.

It is said Altavoir are incredibly rare, only frequently appearing when multiple rainbows form close together. Their scarcity has led many people to believe that this Pokémon is the fabled treasure at the end of the rainbow.

This Pokémon is commonly known to manipulate large amounts of sludge using its psychic power. Unlike other variants of Muk, this Pokémon smells faintly of cotton candy; researchers have been unable to determine the reason for this.
