Continuing from Mutant Agenda, Wolverine and Spidey are about to do battle before they are attacked by the Hobgoblin and Landon's security system. Once Wolverine realizes that Spidey is innocent of Beast's disappearance, the two infiltrate Landon's lab to find Hank.
Meanwhile, Beast is the test subject for Landon's project, which is not to cure mutations, but destroy mutants outright. Unknown to Landon, a spy for the Kingpin is relying the information to Fisk, who is hoping Landon is creating an army of mutants for his world conquest, but once the spy reveals the truth about Landon's plans, Fisk orders him to destroy all evidence of their presence and pull out. Meanwhile, Hobgoblin decides to have some fun, and downloads all of Landon's work onto a CD-ROM before deleting the original data from the computer mainframe, leaving the CD with the only copy left.
Wolverine and Spidey attack Landon's lab and attempt to save Beast, and they succeed when Landon is distracted saving his research from the Hobgoblin, only to end up falling into the tank that he was going to dip Beast into when he tries to catch the CD after Hobgoblin dropped it. Hobgoblin takes his leave when Landon's assistant opens fire on him, and as Spidey, Wolverine, and Beast regroup with her, they watch as Landon struggles out of the tank, before the effects of the chemicals begin to take their effect on him. Having not considered what the stuff would do to an ordinary human being, Landon ironically becomes the one thing he hated the most: A mutant. However, it seems his mutation is unstable, and in a bid to ease the pain he's suffering from, Landon begins absorbing electricity from whatever he can get it from to try and stabilize his condition. Taking his assistant hostage, he makes his way into NYC.
The rest of the X-Men soon arrive in the Blackbird to help, and once Spidey explains what they need to do, they get right to work. While Gambit, Storm, and Jubilee keep Landon in one spot, Rogue wraps a cable around him that is attached to the Blackbird, which then lifts Landon away from any electrical sources and attempts to siphon the electricity out of him and into the sky, but Landon's size soon causes the Blackbird to be unable to remain airborne and begin to fall out of the sky. Landon's assistant intervenes, using her mutant powers to stabilize the Blackbird and lower it safely to the ground. As for Landon, he shrinks back to human size, but is permanently changed to being half-human and half-mutant before being taken away for medical treatment. The X-Men offer to take Landon's assistant to see Professor X to help her with her mutant powers, while having found some valuable allies in the X-Men, Spidey is soon directed to see Dr. Mariah Crawford regarding finding a cure for his mutation.
Mutants Revenge provides examples of:
- Adaptational Context Change: In the comics, Beast gained his hairy appearance by having to drink a concentrated form of the mutant gene to keep it out of the hands of anti-mutant activists. Here, he gained it via a botched attempt to cure his own mutation.
- An Aesop: You can always count on The Power of Friendship rather than carry the load by yourself.
- Big Damn Heroes: Landon's assistant, Genevieve, prevents the Blackbird from crashing.
- Big "NO!":Genevieve: (seeing the Blackbird about to crash) No! No more suffering!
- Crossover: As in the previous episode, with X-Men: The Animated Series.
- Didn't Think This Through: Landon ends up being exposed to his own mutant-destroying chemical and transforms into a very monstrous-looking human/lizard-hybrid creature. As noted by Beast: Landon was so fixated on making something that was toxic to mutants that he never took into consideration about how it could affect humans who were never mutants to begin with.
- A Fate Worse Than Death: Genevieve believes it's better for all mutants to die than to suffer living with them and as one.
- Fire-Forged Friends: Spider-Man and the X-Men ultimately become friends.
- Hypocritical Humor: After Spider-Man makes fun of Wolverine, he angrily calls him a "puny little geek". Spider-Man may be a geek, but he is about half a foot taller and much more muscular compared to Wolverine.
- I Am a Monster: What Genevieve believes herself to be. But Beast tells her all she has is her own fear and confusion.
- Irony: Exactly as Beast puts it when Landon falls victim to his own formula and becomes a mutant as a result.
- Also, Genevieve hoped that the cure would end the suffering.
- Magic Floppy Disk: Hobgoblin copies all of Landon's research to a single CD-ROM. It seems implausible that this data was so compact that it would fit on one disc. Additionally, data can't be copied to a CD-ROM at all, the ROM part stands for Read Only Memory.note
- My God, What Have I Done?: Genevieve, for being involved in the experiment that has gone too far.
- Old Shame: In-universe. Beast is disgusted with how much self-hate he had when he first learned he was a mutant and for trying to cure himself.
- Rescue Romance: Spider-Man catches Rogue after the mutated Landon swats her into the side of a building. While Rogue's flight capabilities meant it was unnecessary, she certainly doesn't seem to mind.Spider-Man: I've got you!
Rogue: Bet you say that to all the gals. - Riddle for the Ages: It's never revealed if Landon knew his assistant, Genevieve, was a mutant.
- The Reveal:
- Genevieve's revealed to be a human mutant (specifically, she has the power of telekinesis) and was the one who had saved Spider-Man from the collapsing ceiling in the previous episode.
- Lewald from the prior episode is revealed to have been a spy for the Kingpin.
- Truer to the Text: The concurrent X-Men show depicted Beast as having looked like a blue yeti in his childhood. This episode shows that, like in the comics, he looked relatively normal until an experiment permanently disfigured him.
- Villain: Exit, Stage Left: With the chance for profit gone, the Hobgoblin blasts open a hole in the ceiling and flies off.
- Unit Confusion: When deploying the equipment to drain Landon's energy, Spider-Man instructs Beast to set the frequency to 28 micro-farads. Farads are a unit of capacitance, frequency is measured in hertz.
- Unwitting Instigator of Doom: Hobgoblin's stand-off with Landon at the lab ultimately leads to the latter being horribly mutated and endangering the city.
- Why Did It Have to Be Snakes?: Landon's transformation makes Spider-Man think of his Neogenic disease turning him into a similar monstrosity endangering public safety.
- You Are What You Hate: Landon becomes a mutant while Genevieve's revealed to be a self-hating mutant that desperately wants to be cured.
