Gator is a U.S. SEALs operator.
Through unknown circumstances, the soldier known by the call-sign Gator joined the U.S. SEALs, where he eventually earned his call-sign.
Gator and his unit were part of an apparent exercise in which they had to resecure Hell Island. His team's objective was to check out the Aircraft Carrier just off the island itself.
However, Gator's team arrived in a hanger modified for warfare, they discovered several sets of severed hands, and relayed this information to the other military teams that were on the carrier. However they were suddenly attacked by several hundred gorillas modified to be soldiers, and Gator, along with the rest of his men, were all killed.
