Hyena Jack

Hyena Jack was a pirate who operated out of the Cimerrean. His name comes from a single mutated eye that allowed him to see in the dark and gain an advantage on his enemies.
He was hired by the White Lion Armada to pursue and intercept Professor Halle while escorted by Simon lion city, and procure the Progenitor Atlas. Simon's first mate cut a deal with Jack to spare the crew's life if he delivered the Professor. Simon nevertheless fought for Professor Halle's life and challenged Hyena Jack to a duel, whereupon he dealt the pirate captain a mortal blow.
Hyena Jack's crew honored the deal, letting Simon and Professor Halle live, but took the Progenitor Atlas with them.
