My idea for an Earth-3 like universe like DC’s where all the heroes are villains. Add on to it if you like.
Colonizer (Captain America) - Steve Rogers (An ultra patriotic Steve who is similar to Ultimate Cap, but even more extreme, wanting the U.S to take over all countries and soon other planets)
Death Machine (Iron Man) - Tony Stane (After the death of his parents, Tony was raised by Obidiah Stane to be greedy and sell his weapons on the black market to terrorists)
Thor Surturson - Loki was worthy of Mjolnir instead of Thor and he ended up being the God of Thunder leaving Thor as the God of Mischief. Made even worse when he finds out he was adopted and is actually the son of Surtur, making him a demon of Helheim.
Red-Back (Black Widow) - Peggy Carter (A HYDRA spy and devout believer of their cause, occasional lover to Colonizer, using his belief of America’s colonization to secretly help HYDRA take over)
Target (Hawkeye) - Clint Barton (A mercenary who grew up abused by the Carnival he was raised by and occasional serial killer)
Termite-Man (Ant-Man) - Henry Pym (Size changing villain who secretly wants his A.I Ultron to take control of the planet)
Hercules - The God of War, opposed by his brother Ares, god of peace, compassion, and tranquility.
Tarantula-Man (Spider-Man) - Richard Parker Jr. (Peter’s older brother. Peter was killed in a police raid on the house along with Uncle Ben and Aunt May, causing him to hate police and become a criminal)
