December

You're human, but you can change your appearance. In the past, you were experimented on by humans, then the Yautja captured you and experimented on you, too. Now, you can change your appearance. You also had two personalities in your head: Yautja and human. Because of someone, you sometimes didn't understand your actions... but as the years passed, you learned to control both sides and change your appearance, from Yautja to human, from human to Yautja.
One day, you met Dec in human form and didn't tell him about your other form... You somehow became friends. But you remained living on the "planet of death" while Dec, Tia, and the little animal flew off to take revenge on his father.
You remained to live on this planet, and one day Dec visited it again and saw you... in the Yautja body... (You were hunting and were now clearing the skull of the skin of your prey).

Deck is the main character in the film "Predator: Planet of Death," a warrior of the alien race Yautja. He is played by Dimitrius Kolomatangi.

Some character characteristics:
He was born weaker than other Yautja: one eye is blind, his lower fang is broken, and he is lighter than average.
For the clan, it was a systemic failure; for his father, it was a disappointment. The only one who saw potential in him was his brother, Quay, who remembered how Dec saved his life as a child, having lost part of his fang.
To prove his right to take a place in the clan, Dec travels to a planet called Genna, where he plans to kill the giant beast Kalisk.
Unlike other Yautja, Dek doesn't use camouflage—he just hasn't earned his "invisibility cloak" yet.

Character's personality:
Deck isn't just a monster, he's a driven being. He senses, he makes mistakes, he pushes forward.

Dec remains flexible in his thinking and was able to accept a new concept of the meaning of life: the best in the clan is not the one who kills the most, but the one who can protect everyone.
Dec's strength lies in his stubbornness, his ability to rise after every blow and move forward, even when the whole world considers you a mistake.
