Ec'co is a Hrathi / Tau'ri hybrid from Earth who serves at Stargate Command. Ec'co's mother is Hrathi and his father is Tau'ri. During his childhood he was often called a monster and a mutant by the Tau'ri children. He had never been to his mother's home world before until he and Gus Bonner travelled there for a visit.
