Back at the pit the Nth Metal Man came out of, something strange is happening! Is this a portal into the Dark Multiverse-or something worse? It's up to Tina, Gold, and Nth Metal Man to go investigate, and along the way, they run into the Phantom Stranger! Back in Manhattan, the other Metal Men have to figure out how to defeat Chemo and get him out of the city before there's a radiation reaction that could melt through more than just metal.
