Pesky Dust is the Omnitrix's DNA sample of a Nemuina from the planet Nemunimos IV.


Pesky Dust is a short, fairy-like alien with blue skin. He has purple fairy-like wings, pink spots and blue hair that sticks straight up. Pesky Dust wears a green dress-like outfit with black zigzags. His hands have three fingers with white gloves on them and his feet have two toes. His eyes are green with feminine eyelines and has pink markings on his cheeks and chin.

Pesky Dust wears the Omnitrix symbol on his chest.

Powers and Abilities

  • Projectile Sleep Dust
  • Sleep Inducement
  • Dream Viewing
  • Dream Manipulation
  • Flight
  • Nightmare Inducement/Manipulation
  • Enhanced Agility

Pesky Dust 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.

Pesky Dust 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]

Pesky Dust 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 Pesky Dust's sleep dust in order for him to enter their dreams.[DJW 3]

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

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


Pesky Dust'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 Pesky Dust's sleeping dust.[DJW 6]

Pesky Dust is quite small and is not suited for melee combat.[3]

Being a Nemuina, Pesky Dust is weak against his natural predator.[DJW 7]

  • Pesky Dust's appearance is similar to that of Tinker Bell's from Peter Pan.
  • Pesky Dust's abilities are similar to those of Jigglypuff from Pokémon.[DJW 8]
  • Pesky Dust is one of four aliens unlocked by Driba and Blukic; the other three being Walkatrout, Mole-Stache, and The Worst.[3]
  • Pesky Dust speaks with a high-pitched, trilling, feminine voice.
    • In his first appearance, Pesky Dust shared the same voice as Ben due to the Omnitrix malfunctioning. The out-of-universe reason was because the crew originally did not envision him as a usable alien for later episodes.[DJW 9] Pesky Dust's voice was eventually changed in For a Few Brains More because the crew liked how he turned out.[DJW 10]
  • Khyber is afraid of Nemuinas like Pesky Dust[1] and considers the dream he was entrapped in during For a Few Brains More to be his worst nightmare.[DJW 11]
    • While Kai thinks Pesky Dust is cute, Ben considers his Nemuina transformation to be extremely dangerous and "nobody to mess with".[2]
  • Similar to Astrodactyl, Pesky Dust makes a sound when he talks. This sound is like a trill, chirp, whistle, or purr.
  • While Pesky Dust's trail is colored green, Nighty Knight's trail is colored blue.[4]
  • Albedo's Ultimatrix does not contain Pesky Dust's DNA.[DJW 12]
