Much of Deadpool & Wolverine remains shrouded in secrecy, though we expect Emma Corrin's Cassandra Nova to be the threequel's big bad. We don't know whether she hails from the X-Men Universe or is among those trapped in The Void; either way, it appears Professor X's twin will be a formidable threat.
Scooper @Cryptic4KQual has shared some new details about Cassandra today, including the fact she's "faithful and true" to the comic books.
Apparently, Nova is "evil and twisted [and] a serious nutcase of a villain." They add that Cassandra "has no [regard] for life and is a very formidable adversary." The leaker later says Magneto's helmet is at one point mentioned as a means to fight her telepathic abilities. Unfortunately, "she already got to it."
Daniel Richtman has also shared some intriguing details about Deadpool & Wolverine, explaining that the movie introduces a new concept to the MCU where there's one specific being in every universe and, without them, their respective reality will die.
This should be a familiar concept to comic book fans as it's an idea Jonathan Hickman introduced when he brought back Molecule Man. The Beyonders created him as a singularity across every reality, giving the former villain the function of a "bomb" that would destroy his respective universe if he were to die.
Essentially, Molecule Man became the default origin of Incurisons, with Doctor Doom later collecting his Variants to use as a weapon against The Beyonders. Who will take on this role in the MCU? Wolverine, Deadpool, or someone else? We'll have to wait and see.
In the comics, Cassandra is a "Mummudrai," a spirit that's considered the equal and opposite of a person in Shi'ar culture. However, given Charles Xavier's incredibly powerful latent mutant powers, his Mummudrai took on a physical form in the womb as his "twin."
However, the baby Charles instinctively recognised her as a threat and the ensuing battle saw his and Cassandra's mother miscarry the X-Men leader's sister.
It was later revealed she'd survived as a mass of cells in a sewer wall (seriously), managing to build a body for herself while planning the ultimate revenge on Charles. That included taking his place and the murder of 16 million mutants by unleashing giant Sentinels on the nation of Genosha.
