Trentonalleo was related to the guy who got turned into Devingee. When that guy did get turned into Devingee, he inexplicably managed to get back to Universe Alpha and obtain some of "Trenton's" DNA, and gave him an brain scan. After mixing it with some of Malleo's DNA and tinkering with a cloning machine, he created a full-grown, perfectly-healthy hybrid of two that became known as Trentonalleo, complete with Trenton's memories and personality. After explaining what happened to Devingee and what Weegee and the Trolliverse were, Trentonalleo moved to Planet Nachuma with his adoptive brother.
