Nighty Knight is the Omnitrix's DNA sample of a Nemuina from the planet Nemunimos IV and the Dimension 23 equivalent of Pesky Dust.


Night Knight looks mostly the same as Pesky Dust except his clothing and gloves are colored blue, his eyes are light blue, and his skin is a lighter shade of blue. The Omnitrix symbol on his chest is blue with a gold outer casing.

Powers and Abilities

Nighty Knight is capable of flight, and possesses enhanced speed and agility thanks to his fairy-like wings. He can also leave behind a green trail while flying.

Nighty Knight can release a special kind of dust that makes his victims fall asleep, such as Zaroffians,[1] Pugnavores,[2] Polymorphs, Galvanic Mechamorphs,[DJW 1] and even Celestialsapiens.[DJW 2]

Nighty Knight can enter and examine the dreams of others, which can be used as a form of interrogation or extracting information from a victim.[1] However, they must be affected by Nighty Knight's sleep dust in order for him to enter their dreams.[DJW 3]

If Nighty Knight were to keep dousing a victim in his sleeping dust, they would end up sleeping forever.[DJW 4]

Nighty Knight can manipulate a victim's dreams, causing them to have nightmares instead.[2]


Nighty Knight's abilities would be useless against technological or robotic opponents, who cannot fall asleep or have dreams. He can also be affected by the abilities of other Nemuinas.[DJW 5]

Members of Gutrot's species are immune to Nighty Knight's sleeping dust.[DJW 6]

Nighty Knight is quite small and is not suited for melee combat.[3]

Being a Nemuina, Nighty Knight is weak against his natural predator.[DJW 7]
