- Arctiguana first reappeared in The New Outbreaks. The broken Omnitrix sent a small amount of energy through the Plumbers Headquarters, affecting some prisoners, one of which was Liam, who became Arctiguana. He was broken out by Psyphon as Jetray, who he then helped to try to escape the Headquarters. He was defeated by Snot Goblin's mucus minions before being transformed back, only to fight Kickin Hawk.
