(I do not own the franchises in this fic. My Hero Academia is owned by Kohei Horikoshi as the creator of the manga and Shueisha as the publisher. The anime adaptation is produced by Studio Bones. Funimation, now part of Crunchyroll, holds the international distribution rights for the anime. Tokusou Sentai Dekaranger and it's characters are owned by Toei Company, Ltd.)
In this world, justice is maintained by two main forces:
The Pro Heroes, who take down villains and maintain societal harmony.
And the Special Police Dekaranger, who confront extra terrestrial offenders called Space Criminal Alienizer.
Ideally, these two groups should collaborate-but they don't. The reason? The Dekarangers do something all heroes try to steer clear of: eliminating criminals designated for deletion.

Izuku Midoriya always dreamed of becoming a Pro Hero like his idol All Might... but that dream was shattered when, during an Alienizer attack, he killed one in self-defense to protect Katsuki Bakugo. Now with a black mark on his record and labeled a killer, Izuku's future seemed to be forever ruined... until Commander Doggie Krueger of the Earth branch of S.P.D. gives him another chance. Not to become a Pro Hero, but something else.
To become... a Dekaranger.
Izuku finds himself welcomed into the ranks of S.P.D., a specialized force of officers who've become his first real friends, united in their mission to defend Earth against extraterrestrial dangers.
Together, they will confront the Alienizers, connect the Hero world with S.P.D., and discover the true essence of being a hero.
They are: Tokusou Sentai Dekaranger.
