A member of Nighthawk's Redeemers, Redstone, a later creation, is a counterpart to DC Comics and Detroit Justice League character Steel.

Redstone's ties to the Earth proved to be more intimate than he realized for after leaving the planet and traveling into outer space with the Squadron to confront the Nth Man and prevent him from destroying the universe.

[volume & issue needed] Michael Redstone was an imprisoned renegade soldier and serial killer who murdered six women (five prostitutes and one Sergeant Alicia James.)

A secret government group had been grafting a retro-virus based on Hyperion's DNA to military convicts who volunteered as human guinea pigs.

[volume & issue needed] After getting his powers (super strength, invulnerability, and "Flash vision"; notably, he does not gain Hyperion's ability to fly), he and an unknown number of other test subjects escaped.

Redstone resumed killing prostitutes, again mostly black women, but this time in greater numbers, attracting Nighthawk's attention.

General Richard Alexander makes a deal with Redstone, and has him dropped into an unknown country whose government is being what the United States considers difficult.

[volume & issue needed] The Redstone of the Squadron Supreme's Earth possesses superhuman strength, stamina, and durability.
