Fox should share the X-Men,FF,Deadpool and Wolverine rights with Marvel because we all want to see Hulk and Wolverine fight. We all want to see The Avengers,Guardians of the Galaxy,X-Men,Fantastic Four,The Inhumans and other heroes go against Thanos in the Infinity Wars. Think about it...if Fox shares the rights with Marvel Galactus,Kang the Conqueror andThe Skrulls could be in the MCU. Think about all the possibilities.
We could probably see Wolverine in his traditional costume.
This would be GREAT.
If Fox shares the rights, THIS could happen. We would have the whole Marvel Universe! Then all these heroes can go against Thanos in the Infinity Wars.
