HYDRA

HYDRA is a subversive organization whose main goal is to take over the world. Originally a branch of Nazi-Germany under the command of Red Skull, it is now an evil organization that has spread across the world.

Its name comes from the mythological Hydra, and their motto is the metaphor "cut a head and two will take its place", proclaiming the organization's resilience to foes. They would usually begin cheering out "Hail HYDRA!", upon hearing their motto.
