– Ampfibian to Sir Morton.[1]

Ampfibian (alternatively spelled as AmpFibian)[2] is the Omnitrix's DNA sample of an Amperi from the planet Tesslos[merch 1] in the Andromeda Galaxy.


Ampfibian is a blue jellyfish-like alien with white swipes on his body resembling lightning streaks, a main body with three-segmented skirt-like parts for his head, chest and abdomen, and six long tentacles that function as two pairs of arms and a pair of legs.

In Ultimate Alien, Ampfibian had pupil-less eyes and wore the Ultimatrix symbol on his chest. His eyes were colored blue in Fused due to being fused with Ra'ad, but were changed to green for the rest of his appearances.

In Heroes United, Ampfibian looked mostly the same as in Ultimate Alien except most of the white swipes on his body were missing while the ones that remained were slightly darker and shaped differently.

In Omniverse, Ampfibian looks almost the same as before, except the lightning streak swipes on his body have been altered, his tentacles are now pointed instead of curved, and his green eyes are larger with the black outlining in them becoming much more prominent. He wears the Omnitrix symbol on his mouth.

Powers and Abilities

Ampfibian can manipulate, produce, and absorb electrical energy, such as lightning and the Piscciss Volann guards' energy net.[3] That energy is then launched out of his tentacles as attacks.

Similar to Ghostfreak and Big Chill, Ampfibian can make himself intangible.[4] Correlating with this, he is capable of electrically shocking any objects and beings he phases through.[5]

Ampfibian can fly and is agile enough to dodge attacks while flying.[6]

Ampfibian can breathe underwater, the latter of which allows him to swim at superhuman speeds. He can also safely produce and discharge electricity underwater.[DM 1][3]

Ampfibian's tentacles can extend multiple times their length.[7][6]

Similar to Upgrade and Buzzshock, Ampfibian can become pure energy in order to enter electrical cables and generate a large energy blast that surrounds him, as demonstrated by Ra'ad.[4]

Ampfibian has degree of enhanced strength, enough to restrain Phil with his tentacles.[8]

Even though his body is frail, Ampfibian is durable enough to withstand being thrown against a wall by Solid Plugg[9] and getting hit by an Aerophibian's neuroshock blasts.[10]

Ampfibian can read both human and Osmosians' thoughts by sensing the electrical pulses of their minds;[DM 2] this feat was only demonstrated by Ra'ad on Kevin.[4]

Ampfibian can survive in the vacuum of space and generate a protective energy shield around himself; these feats were both exclusively demonstrated by Ultimate Aggregor during his visit to the Perplexahedron.[11]


Ampfibian's intangibility is useless against other beings that can also become intangible, as it will cancel out their abilities to do so.[12]

Ampfibian is weak against enemies who can drain electricity, like Phil.[8] Furthermore, Ampfibian's electric attacks are useless against Solid Plugg[9] because he is made out of super dense rubber.[DJW 1]

Since his body is very frail, heavy objects falling on Ampfibian can make him faint.[10]

Despite his durability, Ampfibian can still be harmed by an Aerophibian's neuroshock blasts.[10]

Ampfibian is vulnerable to magic, as shown when he got trapped in Gwen's mana shields.[4]

Despite being able to use his electricity underwater, Ampfibian can accidentally shock himself if he is entering or partially in water, as demonstrated with Ra'ad.[4]

Ampfibian's name is a portmanteau of the words "amper" and "amphibian" (with the "ph" changed to a "pf"). It is also a pun of the word "amplify" ("amp" for short), which means to charge and increase energy, referencing Ampfibian's abilities to absorb, generate, and redirect electrical energy. The word "amphibian" is also used since most are either adapted to water, or generate their own electricity.


  • Ampfibian was designed by Steven Choi and Chap Yaep,[DJW 2] and was named by Len Wein.[MW 1]
  • Ampfibian was the Alien of the Month in September 2011.
  • Ampfibian and the other Andromeda aliens have powers linked to a certain element; for Ampfibian, it is electricity.
  • Ampfibian is the only Andromeda alien that Ben used in the same episode he was scanned in.[4]
  • As of Omniverse, Ampfibian and Feedback are the only aliens who generate blue electricity.
