Kuruk

Kuruk was a warrior from a faraway land. He left his homeland when his elder brother was made chieftain of his tribe. In exile, this skilled fighter learned to create deadly weapons of his own design to remarkable effectiveness. His great strength and short fuse made him a force to be reckoned with.

In 2012, his genetic memories were used as an Animi Avatar by Abstergo Industries, in the third stage of training for their recruits in the Animi Training Program, under the title of the Bear.
