Chamalien

ChamAlien is the Codon Stream's DNA sample of a Merlinisapien.

Appearance
ChamAlien has a slim body that resembles a large gray lizard with darker gray 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 dark-purple, 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 and speaks in a high-pitched German accent.

ChamAlien wears the Ultimatrix symbol on his chest.

Powers and Abilities
ChamAlien can change the color of his skin to become almost invisible.

ChamAlien is very agile, quick, flexible and slippery, making him very difficult to grab.

ChamAlien can scale walls with ease.

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 with ease.

ChamAlien works well when stealth is needed.

Weaknesses
Although ChamAlien could become almost invisible, his shadow still remains. So any place filled with too bright lights can be a disadvantage.

ChamAlien (like all living beings) can still be detected by his mana even when camouflaged.
