The Galvan are an amphibious, insectivorous species from the planet Galvan Prime, until it was destroyed and they rebuilt it, renaming it Galvan Mark II.


The Galvan are a species of small bipedal frog-like amphibians.

Galvan are about five inches tall on average. Their bodies consist of soft and flexible bones, allowing them to squeeze into tight spaces or quickly escape from danger.

The Galvan have large, bulbous eyes with thin lines for pupils. Unlike humans, Galvan eyelids close horizontally and from both sides of the eye. Normal Galvan have green eyes,[DM 1] except Albedo, who has red eyes as his colors were inverted.[1] Galvan from Dimension 23 have blue eyes.

Infant Galvan look like tadpoles; they have tails and lack legs, but they grow legs and shed their tails at a time they call "wisdom feet".[DJW 1]

Female Galvan grow thin tendrils on their head. Male Galvan grow similar tendrils but on their chin, when they turn into adults.


The Galvan originally had no empire to speak of, instead they were first kept as pets and then employed by other species as industrial technicians, spies, and saboteurs once their intelligence became known.

The Galvan were smart enough to keep the best secrets for themselves, eventually amassing enough knowledge to build a powerful empire of their own, based on the technology that they kept from the rest of the universe.

Most of the Galvan are known as technological geniuses.[2][3]

There are some Galvan that live outside the cities of Galvan Prime that have less tech-focused lives.[DJW 2]


The Galvan are insectivores,[DJW 3] as seen when Blukic eats one of Dr. Animo's bugs.[4] Some Galvan, such as Azmuth,[5] Blukic, and Driba,[6] also have a liking for smoothies.

It was demonstrated by Grey Matter that Galvans can eat jellybeans.[7]

Powers and Abilities

The Galvan are naturally extremely intelligent and can enter complex machines and operate them from the inside. This allows them to understand and operate virtually any machine, even if they've never seen it before.[pop-up 1][8] Their intelligence also allows them to understand intricate codes and languages. The Galvan are the smartest beings in the galaxy.[DJW 4]

Even if something is unfamiliar to them, Galvan can learn it very quickly. After all, their intelligence extends beyond technology and biology.[DJW 5]

When the situation requires it, the Galvan are able to jury-rig or improvise weapons and emergency repairs, using whatever materials that they have on hand, like loose change, belt buckles and shoelaces.

With the microscopic pads that cover their bodies,[pop-up 2][9] the Galvan can stick to almost any surface. Their slime makes them equally difficult to grab.

Not built for combat, the Galvan can evade and outsmart their enemies, rather than fight them head-on.

The Galvan have teeth sharp enough to produce a painful bite.

Similar to frogs, the Galvan have long sticky tongues, which they use to capture insects for food.[4]

The Galvan can breathe underwater because they possess gills, making them amphibious.[DJW 6]

The Galvan have two brains, the main brain, and a pre-brain. The main brain has the appearance of a glowing green sphere, which is able to survive completely separate from their body and speak. The pre-brain handles the basic bodily functions, much like the medulla oblongata does for the human brain. However, this pre-brain is simplistic and childish. As quoted by Max, it makes Blukic and Driba look like geniuses in comparison.[10][11][12]


A Galvan's small size makes them unsuitable for physical battle, so they must outsmart their enemies in a fight. Animals like dogs and cats can be a problem, as they may see them as a chew toy or food.[13]

Despite possessing immense intelligence, Galvans can still make miscalculations, as Grey Matter's attempt to upgrade the Rust Bucket's air conditioner caused it to overheat instead, incapacitating the vehicle.[14]

Galvans would be vulnerable to being trapped by a member of Omnivoracious's species if they were not extinct.[15]


The Galvan are the creators of much of the great technology and made many discoveries in the universe, such as:

By Albedo

The name Galvan is a reference to Italian physicist Luigi Galvani, who discovered the electrical impulses of the nervous system by performing experiments on frogs (hence the Galvan's frog-like appearance).


  • Initially, female Galvans had hair while male Galvans did not.[pop-up 3][16] This was retconned in the sequels, where no Galvan have hair.[17]
  • The Galvan have extremely long life-spans, with Azmuth himself already several thousand years old, and expects to live at least another three thousand years.[18]
  • The Galvan were the first species added to the Omnitrix.[DJW 11] However, the DNA sample used for Grey Matter did not come from either Azmuth or Albedo.[DJW 12]
  • Galvan technology is very eco-friendly and works in harmony with nature. Even their domiciles are a grown techno-organic fungus.[DJW 2]
  • The Techadon Weapon Masters don't accept the fact that the Galvan are smarter than them. So, they try everything to make the Galvan look bad.[GT 1][GT 2]
  • The writers' naming convention for Galvan in Alien Force and Ultimate Alien was to use astronomical terms.[DM 2]
  • Primitive Galvan worshipped technology as gods.[pop-up 4][9]
  • The Galvan intellect is apparently highly revered as even the Highbreed Supreme said that the Galvan were "a slightly more intelligent form of pond scum".[19]
  • The Galvan have been involved in Earth's history countless times, including building the pyramids,[20] building the Stonehenge as a prank,[21][22] giving Ascalon to Sir George,[17] causing the Roswell Incident, and protecting Earth from Benevelon's attack before it was incorporated.[23]
  • The Galvan are currently the species that have the most named characters in the show, besides humans.
  • Derrick J. Wyatt considers Azmuth, Albedo, and other Galvan characters to be analogs to Grey Matter, who was absent in Alien Force and Ultimate Alien.[DJW 13]
  • In Nega Ben's timeline, soon after the creation of the Omnitrix, the Galvan were wiped out by a rogue Celestialsapien coerced by Maltruant.[DJW 7]
  • The Galvan admire the Planchaküles' industriousness and skill, but prefer not to hang out with them too much after work.[DJW 14]
  • The idea to name multiple Galvans after creators of the series started after T.J. Collins named Blukic and Driba.[DJW 15]
  • Had Omniverse continued past Season 8, a Galvan colored like a poisonous frog would have appeared as a member of the Negative 10, but not as the group's leader.[DJW 16][DJW 17][DJW 18]
