Okay, so theres probably not enough hope and wishful thinking in the world to make this a reality, given how 90% of the rest of the Marvel Universe is owned by Disney and the House Of Mouse is unlikely to allow a psychotic mercenary from a rival studio to pull out their giblets. As you may have guessed from the imaginative title, Deadpool Kills The Marvel Universe pits the merc with a mouth against just about everyone you can imagine after hes pushed to the very edges of his psychosis in Ravencroft Institiute. If Im being honest, Deadpool Kills The Marvel Universe will probably never escape the page, but theres a chance it could work as one-off animated film since the rights work differently. Still, thered presumably be nothing to stop Deadpool name dropping the MCU and going off into a rambling monologue about a superhero slaughter spree or at least taking care of the latest version of The Fantastic Four if Fox is still feeling malicious.
