Gills grew up in Quintana Roo, Mexico spending most of his young life diving and exploring miles of underwater caves. His skills in diving developed so much that he could dive underwater for 25 to 28 minutes without surfacing and holding his breath for up to 30 minutes. Instead of becoming an Olympic swimmer, he chose to join Sea Squad to use his talents to help people.
After being on hundreds of successful rescue missions he has now been reassigned to combat duty to help protect his beloved ocean. The Curse! had started sinking battle ships that guarded civilian supply ships traveling from South America. With The Curse! destroying more and more of The Corps!® battleships it was essential to have a team member that knew the area and could help them regain dominance in the water.
