Madame Web sends Spidey to an alien world, after telling him she's a being of pure energy and that she searches for champions. So, Spidey is sent to the world, the Beyonder's, where he's told he must past a test which includes seeing who is stronger, good or evil. Beyonder sends evil, ALA Red Skull, Smythe, Doctor Doom, Lizard, and Doctor Octopus, to a planet, and causes a year to pass. Chaos is a result. Spidey's job is to save the planet. He's sent to the world, and Beyonder tells him he gets to have help. Spidey is faced in front of a machine that can bring so called heroes, from anywhere. Spidey calls for the Fantastic Four, Iron Man, Captain America, and Storm. They arrive, and Spidey tells them the story. Seconds later, the Lizard busts out of a room in the compound and attacks. The team eventually stops him. While talking again later, Spidey or none of the others pay attention to Lizard, and he escapes outside. They run out after him, and confront sandworms. Narrowly, they get inside and turn on the building's force field. Later, Mr. Fantastic puts Lizard in an alien machine, and brings out the Curt Conners persona of the Lizard. Lizard then joins the team. The episode ends with everyone joining Spidey, and Spidey telling Lizard how he has a tape recorder and is going to record everything.
