The Guardians witness some alien anomalies in battle with the Masters of Evil. Who or what are these doppelgänger beings attacking both sides? And what can stop their constant duplication? The Guardians and Masters of Evil vs. lookalike extraterrestrials!

An Infinity War crossover: The new Masters of Evil show up in the Avengers Mansion only to be opposed by the time-traveling Guardians. Then murderous alien doubles of -everyone- show up to kill and or replace. Constantly replenishing alien doubles. Everyone works together and stays alive. When outside-the-book forces stop the flow of doubles, Doctor Octopus wants to start the fight all over again. The other villains, feeling a little grateful to the heroes who saved their lives, chase Doctor Octopus out of the mansion. Then Jarvis makes everyone left clean up. Thanks, Jarvis.
