The Galvanic Mechamorphs, sometimes shortened as Mechamorphs, are a technological alien species accidentally created by the Galvan from Galvan Prime's moon, Galvan B.

The Galvanic Mechamorphs were first brought to life as a complete accident. Galvan B was originally an uninhabited moon, orbiting Galvan Prime. Galvan scientists, led by Azmuth, were originally working on a project to make Galvan B habitable, but it went farther than intended when a sentient new species came to life. It didn't take long before the first Galvanic Mechamorphs came to join the galactic community and meet their creators in person. Azmuth and the Galvan were surprised by the unexpected result of their experiment on Galvan B. Deciding they had no right to continue their colonization project, the Galvans allowed the Galvanic Mechamorphs to have their home. With the Galvans' help, the Galvanic Mechamorphs built a great civilization within days.

The Galvan and Galvanic Mechamorphs are peaceful neighbors.

Appearance: Galvanic Mechamorphs are a techno-organic species with a gel-like body composed of small cell-like creatures called nanites. They have a green color scheme and have one cyclopean eye in the center of their face. Their bodies are covered entirely in a circuitry pattern that can vary from Mechamorph to Mechamorph. A Mechamorph's eyes can change shape depending on their emotion, such as pointing downwards in feelings of anger, or upwards in feelings of sadness or surprise.

Galvanic Mechamorphs can come in a variety of forms, some of them resembling animals, and some appearing as trees and other plants. They can also be thin, tall, robust, wider, etc.

Powers and Abilities: Due to being comprised entirely of nanites, Galvanic Mechamorphs are completely amorphous. Their humanoid forms can reshape and move like a liquid does.

Galvanic Mechamorphs have the ability to merge with and possess any technology by encasing their liquified body over it. The size of the device is not significant and they control it as naturally as they would their own body. When they merge, their black and green circuitry pattern spreads across the technology's surface to fit its proportions; although they also have the ability to perfectly replicate the technology's original colors.

A Galvanic Mechamorph's technological possession can work on non-electrical machinery, such as a row machine in a gym. Their ability even extends to sentient beings that are mechanical in nature; or, at most, organic beings with some machinery integrated within them.

A Galvanic Mechamorph's DNA is "programmed" with blueprints and intimate knowledge of every alien technology. This allows them to enhance any tech they are possessing into "ultra-tech", making it far more advanced and futuristic beyond human capability, and causing new features to form. After they separate from the machine, it returns to normal.

Galvanic Mechamorphs can transform the technology they are possessing with seemingly no limit, such as upgrading a baseball pitching machine to produce a seemingly infinite number of baseballs; and transforming vehicles into battle-ready machines and mecha-suits. They can also reconfigure their constructs at will to suit any situation, from summoning arsenals of heavy energy weapons and extra limbs, to changing their shape completely. If a Galvanic Mechamorph possesses a computer or control terminal, they can read local information from it, hack it, and manipulate it to execute commands as they wish, even over entire networks. 

Once merged, Galvanic Mechamorphs are capable of destroying and dismantling machines. They can also repair damaged machinery with ease and come out unscathed. They are also able to restore manipulated or conjoined technologies back to their original states.

Due to their nanite liquid-like physiology, Galvanic Mechamorphs' bodies are very mobile and hard to pin down. They can pass through all sorts of small spaces, can be bisected any number of times with no harm done to them, and easily rejoin any separated pieces of themselves.

In their humanoid forms, Galvanic Mechamorphs are also very flexible, and can stretch themselves very far.

Galvanic Mechamorphs can use their shapeshifting to form various weapons and tools from their body, both while in their humanoid form or when possessing technology. They have been shown forming tentacles, spikes and spiked maces.

Galvanic Mechamorphs can generate solid constructs made of their nanites, such as pillars and spikes.

By energizing their biomechanical blood, Galvanic Mechamorphs can launch a powerful green plasma blast from their eye. The blast can also explode on contact or be made to create a delayed spherical explosion at their target destination.

Being inorganic, Galvanic Mechamorphs are able to survive in the vacuum of space. They also don't need to breathe underwater.
