Nemuina

Nemuinas are a fairy-like species from the planet Nemunimos IV.

Biology
Nemuinas are small blue fairy-like aliens with purple pixie-like wings, dark blue hair, colorful eyes with feminine eyelashes, and pink markings on their cheeks and chins.

Female Nemuinas look similar to males.

Predator
Nemuinas have a natural predator that they are vulnerable against.

Powers/Abilities
Nemuinas possess enhanced speed and agility, and are capable of flight thanks to their fairy-like wings.

Nemuinas can release a green dust that makes others fall asleep.

Nemuinas can enter and examine the dreams of beings affected by their sleeping dust, which can be used to interrogate them or extract information. Similarly, they can manipulate a victim's dreams, causing them to have nightmares instead.

Weaknesses
A Nemunia's abilities are useless against robots because they can neither fall asleep nor have dreams.

Behavior
Nemuinas speak with a high-pitched, trilling, feminine voice.

Omnitrix Transformation
The Omnitrix's Nemuina representative is named Pesky Dust, who first appeared in the Omniverse episode "Outbreak" when Blukic and Driba tried to repair the Omnitrix. Pesky Dust solely appears in Omniverse.

The Ben Tennyson of Dimension 23 has an equivalent of Pesky Dust named Nighty Knight, who first appeared in the Omniverse episode "It's a Mad, Mad, Mad Ben World: Part 1".

Etymology
The name "Nemuina" means "I feel sleepy" in Japanese.
