It’s honestly hard to keep up with where these stories go. A long time ago, Peter Parker died in the Ultimate Universe and Miles Morales, a teenager, took up the mantle of Spider-Man. Lots happened, Miles lost his mother, took a year off, fought Galactus and then came back as the Ultimate Universe, once thought on its last legs, got rebooted. I’ve reviewed some of it in the past but now, in the ongoing Miles Morales: The Ultimate Spider-Man series, things go entirely sideways.
If one Spidey is good, why not two?
