Collision Day: May 20, 2023

Two years ago, multiple universes collided. What should have destroyed the universes somehow survived due to the works of the heroes from each universe. Six months after Collision Day, over 70% of the population was affected by sickness and starvation due to doppelgangers and other issues that were difficult to prevent.

The universes that merged together were My Hero Academia, Marvel, DC, Invincible, and The Boys. One good thing about this collision is that the comic books and anyone who had read them had forgotten the identities of the heroes inside them, protecting the heroes' identities.

A year after Collision Day, the MHA universe began to affect the people from other universes. People who used to be normal suddenly started to gain powers out of nowhere. In order to stop the panic, many countries began to ban powers. Due to grown adults gaining powers with no control, it was causing property damage and hospitalizing civilians. That, however, made things worse; so many governments created power licenses inspired by the MHA Hero License. Individuals take a six-month class and then receive a license stating that they are trained and legally allowed to use their power.

Many Hero Schools were closed down. Not every hero wants to work for the government. And many countries have their own laws now on heroes. Many hero agencies were defunded, with many owned by the government as well. Now it's 2025, two years after Collision Day. There is so much different about the world now. So many laws on powers and heroes.
