10 Theories For How Deadpool Could Join MCU
7. Francis Was Working For An Offshoot Of The Red Room
A slightly more subtle way to link Deadpool's adventures to the MCU, the Workshop Francis/Ajax was overseeing could very easily be revealed as having ties to the Red Room. That shady organisation is set to be the focus of the upcoming Black Widow movie, and many fans believe the movie will even feature a mention of the sinister Weapon X programme (which ties into Wolverine's origin).
Perhaps the Workshop is somewhere the Russians used to try and activate the dormant X-Gene, something many believe will happen on a worldwide basis in either Eternals or as a result of the "Snaps" which occurred when the power of the Infinity Stones was unleashed on multiple occasions?
If it's too late for a Black Widow tie-in, then perhaps S.H.I.E.L.D. could be involved as it was pretty obvious Ajax had a fair few paymasters. Nick Fury has got up to some shady goings-on in the past - remember those HYDRA weapons? - and the reveal that the man who founded The Avengers was indirectly responsible for Deadpool's creation could set up the aforementioned "Versus" crossover!
