Nega AmpFibian is the Omnitrix's DNA sample of an Amperi from the planet Tesslos in the Andromeda Galaxy.
Nega AmpFibian is a greyish-purple jellyfish-like alien with six long tentacles that function as two pairs of arms and a pair of legs. The end of each segment is colored black and he wears the Omnitrix symbol on his mouth.
Powers and Abilities
Nega AmpFibian can manipulate and produce lightning and electricity, launching them in electrical blasts. He can also absorb electrical energy and relaunch attacks, as seen when AmpFibian did so to the Piscciss Volann guards' energy net.
Nega AmpFibian has intangibility, and is capable of combining that with his electrokinesis to electrically shock any objects and beings he phases through. He is capable of both flight and underwater breathing, the latter of which allows him to swim at enhanced speeds.
Similar to Nega Buzzshock, Nega AmpFibian can become pure energy in order to enter electrical cables and generate a large energy blast that surrounds him.
Nega AmpFibian's tentacles can extend multiple times their length and his lack of bones allows him to squeeze into extremely tight spaces.
Nega AmpFibian can read both human and Osmosians' thoughts by sensing the electrical pulses of their minds and he can survive in the vacuum of space and generate a protective energy shield around himself.
Nega AmpFibian can use his electricity underwater, but if he is using electricity while entering water, or only part of him is in the water, he will shock himself.
Nega AmpFibian's intangibility is useless against other beings that can also become intangible, as it will cancel out their abilities to do so.
Nega AmpFibian is weak against enemies who can drain electricity, like Phil. Furthermore, Nega AmpFibian's electric attacks are useless against Solid Plugg, though the reason why remains unclear.
Since his body is very frail, heavy objects falling on Nega AmpFibian can make him faint.
Nega AmpFibian can be harmed by an Aerophibian's neuroshock blasts.
