Learn the secrets behind Earth's Mightiest Villains and why your heroes should pray they never escape: 

Armory: a psychotic weapons master capable of forming any weapon from the power of mystic crystals brought to Earth by the dreaded Scion. 

Atrocity: the result of a failed WWII super-soldier program, he is raw savagery and unstoppable power wrapped in an immortal body. 

Brainstorm: one of the smartest men alive, a man who believes he is destined to use his genius to rule the world.

Garotte: this hired killer uses his elastic form to enter any room and silently choke his target to death.

Equinox: for decades a mad scientist conducted experiments on his four children to turn them into heroes, when he finally succeeded however, he was the first victim of children traumatized by a lifetime of painful tests and treatments. They are masters and mistresses of the elements:

• Brimstone: her touch is a fiery death, her breath the poisonous smoke of an erupting volcano
• Gale Force: a living creature of air, he can generate a wind to knock down a building or steal the breath from your lungs
• Permafrost: like the arctic she can kill you slowly or in minutes
• Sculpture: the man of granite

Ground Zero: a great scientist turned into a living nuclear bomb by a freak accident, his uncontrollable powers led him to beg for incarceration in Rock City.

The Hollow Men: they claim they are heroes from a future where overpopulation has doomed the Earth but their proposed solution made them enemies of the world. Led by super-genius Walter Frazier, this team of fanatics is determined to reduce Earth's population by 90% by any means necessary.

• Lunatic: a man with the strength and ferocity of a feral beast, he hunts by night and humans are his favorite prey.
• Throttle: as fast and deadly as a bullet, anything he can't fly around he can fly through.
• Aura: beautiful and deadly, this alien lives off the lifeforce of sentient creatures and Dr. Frazier has promised her more than she could ever consume in the bloated race of humanity.
• Grotesque: a gargoyle made flesh, this relentless killer claims to be a mystical creature. Regardless, his sadistic pleasure in the death of the living makes him a terror no one wants to confront.
• Dr. Walter Frazier: this time traveling genius from the future has concluded that only the most radical solution can save humanity from itself. 

Omega: she is the world's greatest assassin, armed with weapons, sensors and body armor of her own design. She could be a great hero but she loves only money.

Shillelagh: The owner of a mystical Irish staff, this madman seeks to rend the veil between dimensions permanently, allowing the beasts of legend dominion over an earth that once was theirs.

Skullcap: no one knows what the motivation of this silent killer is but his psychotic rages are legendary. 

Stigma: once a great hero, this superhuman brute has sworn himself to Brainstorm, content to protect him until his inevitable conquest of Earth.

Strongarm: not the brightest criminal in the world, still, his seemingly limitless might and invulnerability brought him within a hair of uniting half the world's organized crime families under his control. 

Tower: the mightiest robot ever constructed, this relentless machine of terror was initially designed to serve as a new body for the Savant. When the transfer of his consciousness was interrupted by USHER agents, the body somehow became self-aware and is determined to wipe out all organic "viruses" infesting Earth, replacing us with its new progeny. First it will kill its creator, then the rest of humanity.
