WARNING: The following contains spoilers for Heroes Reborn: Weapon X & Final Flight #1 by Ed Brisson, Roland Boschi, Chris O'Halloran & VC's Cory Petit, on sale now.
In the world of Heroes Reborn, the Squadron Supreme are among the most powerful beings in creation. In a world where the Avengers, the X-Men, the Fantastic Four and the rest of the traditional heroes of the world never truly existed as they were meant to be, the world was instead defined by the likes of Hyperion.
However, there have been a handful of figures who've come close to defeating them on occasion -- even someone as strong as Hyperion, Marvel's version of Superman. But when he came up against an enhanced Wolverine, he was nearly defeated by the same tactics that have often been used against Superman.
In the altered world of Heroes Reborn, it turns out that the United States of America -- thanks to the additional power afforded to them by the Squadron Supreme, were more ambitious and willing to expand their territory into Canada. Annexing large swaths of the more profitable parts of the country, the remainder was bombarded with nuclear weapons that left the country a radiated graveyard. From the ashes rose the remnant of Alpha Flight, led by Weapon X -- aka Wolverine of the core-Marvel Universe. Wolverine and his few remaining allies, Shaman, Sasquatch, Aurora and the new Guardian (Claire, the daughter of the deceased Vindicator and previous Guardian) were able to lure the Squadron into a trap.
There, Weapon X was able to ambush Hyperion. While his adamantium claws might be some of the sharpest metal on the planet, even they couldn't breach the skin of Hyperion. Luckily, Shaman was able to enhance his claws, giving them a soft blue hue and making them capable of shifting past his natural defense. With his claws, Wolverine was able to catch Hyperion by surprise and stab him in the chest. Logan even makes special note that Hyperion looked just as surprised by the assault's effectiveness as he was, dropping dead and falling into the arms of a shaken Power Princess. This is actually a very fitting style of attack, given how Superman usually operates.
One of the only ways someone can get the better of Superman is to use mystical attributes to attack him. Superman's powers give him no innate defense against magical attacks, making him vulnerable to figures like Circe. It makes sense then that his Marvel counterpart could be defeated the same way, with someone imbuing one of the Marvel Universe's most dangerous killers with a way to actually get around his nominal invulnerability. In doing so, Logan comes closer than almost anyone else to defeating Hyperion. However, with the team forced on the run to flee his furious teammates, Logan is shocked two years later when the Squadron finally finds them -- with Hyperion is among their number.
Although Weapon X puts up a good fight and it's not revealed how exactly he was restored, it isn't long before Hyperion beats him down -- with Sasquatch betraying the team and holding Shaman at bay in exchange for their survival. The only member of the team not spared is Weapon X, who is ultimately dragged to another world by Doctor Spectrum and left to die on his own. But still, it's notable that Logan, more than almost any other figure in the Marvel Universe, came the closest to actually bringing down the villainous Superman-esque figure, something Doctor Doom, Galactus, and the Hulk all failed to manage on this world.
