History
Captain Russell was Zarathos' right-hand-man and leader of his Night Watch Guards. Little did Zarathos know, Jack was secretly in love with Selene and planned to help her overthrow his boss. When he heard the Exiles attacking, he immediately went to Zarathos to attempt to kill him in his sleep. Of course, this did not go as planned, and Jak was killed.[1]

Powers
Seemingly those of the Jack Russell of Earth-616. Also, Jack was able to transform into his Werewolf alter ego at will, even during the daytime.
