Galvan

Galvans (a play on galvanization) are an extraterrestrial species of bipedal frog-like beings from the planet Galvan Prime.

Anatomy
The Galvan are small frog-like bipedal creatures standing at four or five inches with sharp teeth and grey skin. Normal Galvan have green, orange, or blue eyes whereas Albedo and Dark Matter have red eyes.

Infant Galvan look like tadpoles in the sense that they have tails and lack legs, but they grow legs and shed their tails at a time they call "wisdom feet".

Diet
Galvan are insectivores, and therefore mostly eat insects.

Lifespan
Galvan have an immense lifespan of thousands of years. For example, as a Galvan of considerable age, Azmuth says he expects to "only" live another 3,000 years.

Predator
The Galvan's natural predator is the functionally extinct Omnivoracious.

Powers and Abilities
Known for evasion rather than confrontation and lacking any actual combat prowess, Galvans have developed intellectual capacities far beyond those of neighboring species, being the creators of much of the great technology around the universe. These include the Potis Altiare, the Omnitrix technology, the anti-gravity projectors used by Polymorphs, the Codon Stream, and Universal Translators.

The Galvan's high intellect allows them to create other worlds, such as the Null Void, Primus, and a rebuilt version of their own planet dubbed Galvan MK 2. They have also created other species, including the Galvanic Mechamorphs, Null Guardians, and Voliticus Biopsis.

Even if they do not know something unfamiliar to them, Galvan can learn it very quickly. After all, their intelligence extends beyond technology and biology.

With the microscopic pads that cover their bodies, their slimy skin allows Galvan to stick to almost any surface. They also have soft flexible bones that allow them to squeeze into tight spaces or spring quickly from danger.

Galvan can breath underwater because they possess gills, making them amphibious.

The energies generated by a Galvan's mind lead to an acceleration of synaptic activity.

Due to the alterations Kevin Levin has made to the Antitrix, Dark Matter is more powerful (and most likely smarter) than ordinary Galvan. Unlike ordinary Galvan, he can shoot dark red fireballs from his hands that encase enemies in a similarly-colored crystal and secrete a dark red cerebrospinal fluid that he can manipulate to form crystal weapons.

Weaknesses
Galvan must remain ever vigilant because in a dangerous galaxy, size still matters and they are easily trampled underfoot. Being small-sized means that they do not match physically with most species.

Because of their sticky skin, it is equally difficult to grab a hold of Galvan.

Despite possessing immense intelligence, Galvan can still make miscalculations.

If Dark Matter's cerebrospinal fluid is forcibly extracted from him, it will cause great pain to him and render him incapacitated. In addition, there is a limited extent to how much damage his crystal traps and weapons can take before cracking or shattering.

Society
Galvan are incessant collectors of technology, and are raised to be extremely intelligent, and able to enter and operate virtually any machine, even if they have never seen it before.

Galvan are the smartest species in the galaxy, as their intellect is apparently highly revered. The Highbreed Supreme referred to Azmuth as slightly advanced form of "pond scum". The only race that can compete or even rival with the Galvan's collective intellect is the Cerebrocrustaceans.

Religion
Primitive Galvan used to worship technology gods, such as the one that Azmuth's bio-suit (from when he first met Ben Tennyson and Tetrax) was based on.

Galvan are very loyal to keeping their top research and technology a secret from other species, as they would rather die than just give it up unless there is a good reason for it. This is demonstrated with the need for the Potis Altiare to help Ben defeat a To'kustar known as "Evil Way Big".

Omnitrix Transformation
The Omnitrix's Galvan representative is named Grey Matter, who first appeared in the original series episode "Washington, B.C.". Grey Matter has appeared in almost every series except Alien Force and Ultimate Alien.

The Ben Tennyson of Dimension 23 has an equivalent of Grey Matter named Brainfrog, who first appeared in the Omniverse episode "It's a Mad, Mad, Mad Ben World: Part 2".

The reboot version of Kevin 11 has a mutant hybrid equivalent of Grey Matter named Dark Matter, who first appeared in the episode "King of the Castle".

Grey Matter has also been used by the "What-If" Gwen 10, Ken 10, Race Against Time Ben, and No Watch Ben.
