Mister Doomsday was haunting his enemies. He amassed an army and took down half of the heroes in the Marvel universe, and it was up to the Companions, Friend and Topaz, to stop it. But they couldn't stop it alone. Friend and Topaz hosted tryouts for the team, inviting everyone they could via telepathy. The results were surprising. They found a massive amount of capable recruits.
While hosting their "talent show" the Companions recruited Mindsinger, Topspin, Rockslide, Fastforward, Flashback, Doc, Glob Herman, Excalibur, June, Fantomex, Energizer, Daydream, Kimura, Stonewall, Sabretooth, Naja, Marrow, Cypher, Crosta, Prince of Orphans, Tangerine, Oya, Adam-X, Petra, Lorelei, Darwin, Mantor the Magician, Mictlantecuhlti, Wasp, Mercury, Gravity, Invisible Woman, Karma, Crystal, Weather Witch, Nature Girl, Motormouth, Scorn and Kiden. While nearly harmless to Mister Doomsday's army of villains individually, they were all-powerful when together.
Unfortunately, Mister Doomsday had the U-Foes, the Rock Trolls, and various other metahumans on his side.
The Companions met with Mister Doomsday's forces and all hell broke loose. Topspin, Mindsinger, Doc and Motormouth battled a super-skrull with the abilities of Black Widow, Multiple Man and Venom, while Fastforward, Adam-X, Darwin and Crosta battled the U-Foes. Weather Witch, Kiden and Nature Girl took on Mister Doomsday himself, Flashback took on all five hundred of the Rock Trolls, while Glob Herman, Excalibur, June, Fantomex, Mantor the Magician, Scorn, Rockslide and Petra dealt with Ares. Energizer, Sabretooth, Gravity, Crystal and Oya dealt with a corrupt Kymellian sorcerer. That left Daydream, Kimura, Stonewall, Naja, Marrow, Cypher, Prince of Orphans, Tangerine, Lorelei, Mictlantecuhlti, Wasp, Mercury, Invisible Woman and Karma to deal with Void's rampage.
The heroes eventually won the battle, and the Companions disbanded. Friend became a powerful member of the human/mutant/inhuman Morlocks. With Mictlantecuhlti's help, the fallen heroes who were lost in battle such as Thunderstorm and Goldballs and Mental and Grain Belt were resurrected. The world lived peacefully for that moment.
