In 2019, author Jonathan Hickman ushered in the most sweeping reinvention of a major Marvel franchise in the publisher’s history, inaugurating the X-Men’s“Krakoan Era,”; according to Hickman, though, as much as the beginning of the era was a success, the fact that he wasn’t able to see it through to completion in the way he’d envisioned stands as the “most disappointing creative experience” of his career.

Star Trek’s official crossover with the X-Men unleashed Marvel’s scariest Sentinels of all time. The X-Men’s enemies are many, and the Sentinels may rank as one of the scariest. These relentless mutant killers will stop at nothing to get their prey, giving them something in common with Star Trek’s Borg, and 1998’s Star Trek: The Next Generation/X-Men Second fuses the two together to create pure nightmare fuel.

Marvel has hundreds of mutant heroes, and the X-Men simply don't have room for all of them. Even with the various spin-off teams like X-Force, X-Factor and Excalibur, there are always some heroes who fall by the wayside. Now, Marvel is itting that it's never found the right way to use one incredibly promising character.

The worlds of the Enterprise and Marvel’s mutants may seem light years apart, but the publisher managed to bring the two together in 1998’s Star Trek: The Next Generation/X-Men: Second . Yet beyond being a simple gimmick, the story functions as a sequel of sorts to 1996’s Star Trek: First .

As Marvel continues its vicious reinvention of X-Men lore, Wolverine is going up against a founding member of the iconic mutant team. But while this particular mutant isn't traditionally a match for Logan, a new redesign just made them blood-soaked equals.
