A New Serpent Arises

The Supreme HYDRA, Madam HYDRA, and any number of other names... The leaders of the evil group of villains known as HYDRA. Stopped by a number of heroes in the main universe, but in the multiverse anything can happen. And heroes could become villains, villains like the ones who command HYDRA. One example of this is Earth 1720 where Sue Storm the Invisible Woman was Empress HYDRA, leader of the same organization.

So what happens when some of our heroes arrive in one of those dark universes? Or those from the dark universes arrive in the world of our heroes?

Well... We're about to see what happens.
