Universally revered on Krakoa as sacred, The Five are a group of mutants who combine their powers to become a mutant resurrection machine and restore their species' population.
No More Dead Mutants
Living through numerous lifetimes where mutantkind experiences a tragic and brutal end, Moira MacTaggert manages to work on a plan to prevent all that along with Professor Charles Xavier, AKA Professor X, and Max Eisenhardt, AKA Magneto. This plan leads to the sovereign island nation of Krakoa and the formation of the Five, a group that can bring dead mutants back to life with DNA samples from Nathaniel Essex, AKA Mister Sinister and mental back-ups recorded by Professor X with Cerebro. A series of Resurrection Protocols are set in place by the Quiet Council of Krakoa and must be met before a mutant can be brought back to life, though the exact nature of the protocols remains secret.
Resurrection Incorporated
The Five include mutants Fabio Medina, AKA Egg, Kevin MacTaggert, AKA Proteus, Josh Foley, AKA Elixir, Eva Bell, AKA Tempus, and Hope Summers, each of whom possess their own unique abilities. Under the direction of Professor X, these beings develop a way to bring mutants back from the dead at the Hatchery in Arbor Magna on Krakoa.
Fabio creates golden eggs made up of biological material. Proteus uses his reality-warping powers to alter the eggs just enough to make them viable for gestating life. When a sample of a mutant's DNA—taken from Mister Sinister's collection—is injected into the egg, the life-giver Elixir nudges the process in the right direction by starting cellular growth. The embryo is then sped up to the appropriate age by time-bender Tempus. The group then joins hands so that Hope can unify their abilities to fully create the mutant's husk, or body. Once the husk exits the egg, Professor X uses a Cerebro cradle, or helmet, to access the back-up copies he possesses of every mutant’s mind on Earth to restore their consciousness and memories, getting them back to what they were before dying.
