Imak and his partner Ivan were assassins working for Prince Baran and General Nguyen Ngog Coy in Madripoor. They were ordered to kill Archie Corrigan, O'Donnel, Rose Wu and (presumably) other people connected with Wolverine. Wolverine gutted both assassins in revenge.
Imak and Ivan were equipped with hand-blades in the form of claws. They had no known superhuman abilities.
