Amperi are a species of jellyfish-like beings from Tesslos, a gaseous planet in the Andromeda Galaxy.[1]



Amperi resemble blue and white jellyfish with six tentacles, four of which are their arms while the other two are their legs. Three hood-like parts make up their head and torso, with the upper most being the head and the lower two being the torso.

Powers and abilitiesEdit

Amperi can manipulate and produce lightning and electricity, launching them in electrical blasts powerful enough to harm Vaxasaurians, Florauna, and Evolved Methanosians. They can also absorb electrical energy and relaunch it as their own attacks.

Amperi can read other beings' thoughts by sensing the electrical pulses of their minds.[2]

Amperi can float through the air, and extend their tentacles multiple times their length.

Similar to Nosedeenians, Amperi can become pure energy in order to enter electrical cables and generate a large energy blast that surrounds them.

Amperi are highly adaptable, being able to survive on dry land, underwater, and the vacuum of space.

Amperi can become intangible, and are capable of combining that with their electrokinesis to electrically shock whatever they phase through.

Due to lacking bones, Amperi can squeeze through extremely tight spaces.

Amperi can generate a protective energy shield around themselves, and swim at high speeds.

Weaknesses Edit

If an Amperi is using electricity while only partly in water, they will shock themselves.

Since their bodies are very frail, heavy objects falling on Amperi can make them faint.

Amperi can be harmed by an Aerophibian's neuroshock blasts.

Amperi can be lifted and swung around by a species with as much strength as Solid Plugg's species.

Opponents such as a hybrid Terroranchula can absorb electricity through Amperi.

An Amerpi's attacks are ineffective on Solid Plugg's species, though why is unclear.

Culture and society Edit

Technology Edit

Amperi have developed machinery capable of insulating electricity.

Notes Edit

  • The Omnitrix's Amperi representative is named AmpFibian, who first appeared in the Ultimate Alien episode "Fused" after the Ultimatrix scanned Ra'ad. AmpFibian solely appears in Ultimate Alien and Omniverse.
    • The Ben Tennyson of Dimension 23 has an equivalent of AmpFibian.[3]
    • AmpFibian has also been used by the Prime Timeline Kevin.
  • It is confirmed that the Omnitrix from the Ben 10 reboot contains Amperi DNA.[4] Therefore, AmpFibian is one of the countless aliens whose DNA pod was glimpsed in the episode "Innervasion Part 5: High Override".
