Chamalien

ChamAlien is the Omnitrix's DNA sample of a Merlinisapien from an unknown planet.

Ben as ChamAlien
ChamAlien has a slim body that resembles a large purple salamander with darker purple camo-esque spots all over his body and a short tail. He has three triangular eyes, the left being blue, the right red and the top green, but the red and blue eyes are the only ones that blink, while the green eye doesn't. The top of his head is purple-black, with a spike-shaped fin on the back of his head. He has four-fingered hands and three toes on his frog-like feet. He also has a wide mouth with sharp teeth.

ChamAlien wears the Ultimatrix symbol on his chest.

Albedo as ChamAlien
Negative ChamAlien looks just like ChamAlien except all of his eyes are red.

Powers and Abilities
ChamAlien's main ability is his camouflage; he is capable of blending in with the color of his surroundings with such effectiveness that he appears invisible.

ChamAlien is very agile, quick, flexible and can climb walls with ease.

His body is highly slippery and smooth,making him very difficult to grab.

ChamAlien has a long, retractable black barb that can come out of the tip of his tail.

ChamAlien has enhanced strength and durability, enough to push a car and a huge truck several yards away.

Weaknesses
Although ChamAlien appears to turn invisible when he camouflages himself, he actually just changes his color, so his shadow can still be seen. As such, any place filled with too many bright lights can be a disadvantage.

Vulpimancers and Anodites can track ChamAlien with his smell or mana respectively.
