WARNING: The following contains spoilers for Marvel Zombies: Resurrection #1 by Phillip Kennedy Johnson, Leonard Kirk, Rachelle Rosenberg, and VC's Travis Lanham, on sale now.
When Marvel started its new Marvel Zombies series, there were plenty of questions after the first issue. The first question was how this new series tied into the original, and whether this is a reboot or an entirely different world for the zombie heroes.
This question comes about because of the differences between the two series. While Spider-Man was one of the first heroes to become a zombie in the original series, this time around he is a survivor, traveling with the children of Fantastic Four members Reed Richards and the Invisible Woman. Peter Parker took Franklin and Valeria under his wing, protecting them at all costs, keeping a promise he made to their parents before they became infected members of the Galactus Hive.
However, there is an even deeper mystery than the Galactus Hive, and that mystery could change the scope of the Marvel Zombies universe. This theory surrounds the character of Franklin Richards, one of the most powerful Omega-level mutants in the universe and someone who has created his own world in the past to protect his family and loved ones. He most famously did this after the assault of Onslaught, creating a new pocket universe until things returned to normal.
In the world of Marvel Zombies: Resurrection, Franklin has stopped aging, and has lost the use of his powers. This is similar to events that have happened previously, both when Franklin created a new world in which to hide the heroes after Onslaught's attack, and also in Chris Claremont, Walter Simonson, Louise Simonson, and Jackson Guice's Days of Future Present in 1990, wherein Franklin's powers triggered when he was killed in the future and sent his dream self in the past where he felt safe. There he reshaped the world to his preference, all while denying the truth of his own death.
Adding further credence to the theory is the fact that Spider-Man knows the answer to the mystery of why Franklin isn't aging and also why he has lost the use of his powers. When Moonstone asks Peter if he is ever going to tell Franklin and Valeria the truth behind the mystery surrounding Franklin, Peter simply says "no," almost as if he knows that telling Franklin the truth might disrupt the world as they know it and create something infinitely worse. This scenario could also provide some explanation as to why Peter's spider-sense is now constantly buzzing.
If the past is any indication, the world of Marvel Zombies: Resurrection could be another instance of Franklin Richards using his powers to protect himself. If he did recreate this new world, as the "Resurrection" subtitle suggests, Franklin might once again be not only the most dangerous mutant on the planet, but also the most traumatized.
