He is a tall, fair complexioned man with short blonde hair. He wore two different suits, one of them being a cyan uniform with black accents and boots with his name and the "Friends Of Fish" logo on it, and the other was a silver diving suit with an oxygen pack and belts with pockets, which covered everything but his head.
He was first seen in The Krakken as a henchmen of Jonah Melville along with Duane, pretending to be a member of a fake organization called Friends of Fish. He was with Jonah when the Krakken first attacked them, he tried to save the crate which contained the egg but failed. When the Krakken attacked them at the second time, he tried to hold her up but he was pushed into the lake. After he swam back to their base the Krakken destroyed it, forcing him into the water again.
Jack was most likely arrested later along with Jonah and Duane when the police arrived after Ripjaws saved the Krakken's eggs.
