Being a superhero sounds like a great thing. Having a super power certainly comes with lots of advantages: super speed, super strength, the ability to fly, or turn invisible, are just some of the things our favorite heroes can do.
But there are also costs to being a hero. In the case of Spider-Man, these costs include not being able to maintain stable relationships with girl friends, or parents, or aunts, or uncles. It turns out that Spider-Man and Spider-Woman, no matter what dimension you come from, faces some significant choices. The story of Spider-Man, the canon, must be adhered to. If it isn’t then bad things can happen.
In this clip from Spider-Man: Across the Spider-Verse, Miles Morales is shown that the canon of the Spider-verse is a fragile thing. Miguel O’Hara is trying to tell him that you can’t have it all, but Miles isn’t buying it. Miles doesn’t seem to understand that there’s a cost to being a superhero. This means that Miles may have to allow the death of his father to maintain the continuity of his dimension. Will Miles be willing to make that trade-off? Do the needs of the many outweigh the needs of the few? Miles finds that difficult to believe.
