Warrior - Brutal - Cold.

Loki is a Berserker of the Yellow colony. He was born, and raised, as a warrior, a fighter. Brutal, heavily built and strong, he never quivered at the through of fighting, no matter who his opponents were.

He is considered to be a high-ranked Berserker, would have even reached a General rank if he wished to, but refused several time to be promoted. He never had any interest in leading others, or giving order. He is better at just fighting in the frontline, and crushing his ennemies between his claws.
Surprisingly, under his cold exterior, lack of interest in anything and violent nature, he can be very sweet and caring - but only toward one specific Ufogs, his mate.
