Toad-in-Waiting was a survivor of Cassandra Nova's wild sentinel attack on Genosha. He later joined a gang of fellow former Genoshans amongst the ruins of Hammer Bay and was led by Angelo Unuscione. Along with his fellow gang members he came into conflict with Professor X over control of the island.
The gang was disbanded post M-Day when most of them lost their powers.
Toad-in-Waiting's powers include being able to leap supernaturally long distances and a prehensile tongue.
