Robin DeSanto was an abductee endowed with a hyper-enhanced metabolism- giving her superhuman speed, hyperactivity and an endless appetite for sugar. Robin was inducted into SEMME's Squadron 82. After Mike was moved to Squad 82, she replaced him on Squadron 128. Due to growing up with a father that played around on her mother, she took an instant dislike to the promiscuous behavior of Joe, even as a faint attraction sprung up between them. She eventually helped Joe get together with Rachel, and survived the final battle with the Martians. Leaving SEMME, Robin eventually came to work at Galasso's toy store, soon becoming competitive with Ethan.
