Deadpool's motormouth charisma is a Wade Wilson trademark, but it turns out it's also a superhuman ability - one literally present in his DNA.

Warning: contains spoilers for Immortal X-Men #4!

While few would be surprised to learn that Deadpool is one of Marvel's most popular heroes, what is shocking is that his charisma is apparently a superpower. The revelation comes as Wade Wilson's genetic material is once again used against his wishes, but this time to make a classic X-Men villain devastatingly charming.

The Krakoa era has changed the game for Marvel's mutants, and few have benefited more than Mister Sinister. With his exhaustive collection of DNA essential to the technology that makes it possible to resurrect mutants, Sinister was able to parlay his unique set of skills into total forgiveness for past crimes and a seat on the ruling Quiet Council. However, power comes at a price, and Sinister recently learned there's another version of him out in the world - a human claiming to be the original Sinister, with the mutant fans know and love just a cheap copy.

In Immortal X-Men #4 (from Kieron Gillen, Michele Bandini, David Curiel, and Clayton Cowles), Sinister learns of the threat posed by his double as he's wrongly accosted for being in league with 'Doctor Stasis.' Sinister runs, intending to use a top-secret project to reset the timeline, but ultimately thinks better of it. Instead, he destroys his current body to ensure he's not being controlled, then rebuilds himself from scratch. As part of the process, fans get to see the layers of Mister Sinister, as he begins with his core motivation - that he's the only real person in existence - and then layers on a disarmingly whimsical and charismatic personality made up of Drag Race episodes, Oscar Wilde, and "Deadpool scrapings." Properly 'armed,' Sinister struts back outside to talk his way out of trouble.

It's a fascinating scene, and one that hammers home how Mister Sinister's playful demeanor is truly just another weapon in his arsenal. Writer Kieron Gillen recently described Mister Sinister as "a narcissistic monster hiding behind a comedy persona," and that shines through here, as Sinister pulls the same trick on readers that keeps working on his mutant 'allies' - being charming and culturally savvy enough that it's hard to see him as the monster he is, even when you know the truth. Sinister is well aware that a "memetic stew" is necessary to his charisma, and there truly is no finer source of this than Deadpool, whose meta-textual awareness makes him the perfect observer and critic of pop culture.

Strangely, the description of "Deadpool scrapings" suggests that Sinister isn't just using a telepathic scan of Deadpool's personality, but rather his actual DNA. This isn't unusual for Sinister - he achieved mutanthood by using the DNA of fallen hero Thunderbird - but it's noteworthy that Wade's motormouth charisma apparently extends to his entire genetic structure. Deadpool's DNA is capable of 'welding' mutant powers that wouldn't otherwise gel, so it makes sense Sinister would have explored even its most fantastical applications.

With an incredible healing factor and the awareness he's a fictional character, Deadpool has some truly unique advantages in the Marvel Universe, however it turns out that even his popularity is some kind of superpower - a power that's helping one of the most despicable people on Earth to seize control of reality itself.
