First, the scale effect
In the past, because Disney and Fox ran separately, there were some cartoon characters on both sides, but they could not appear at the same time, such as Iron Man, Hulk, Captain America and so on.
But this time, the merger of the two companies has merged all the copyrights into one company, so these heroes may all appear on one screen after the merger. Then we can see X-Men fighting Wolverine, Spider-Man storming Hulk and so on. Moreover, this combination will be applied continuously, resulting in greater scale effect.
Second, create more heroes.
At present, Disney and Fox have produced many famous heroes through years of operation and accumulation, but this does not mean that they will not create more heroes in the future.
Because after the acquisition of Disney, all the resources of both parties will converge in one place, whether it is the creative ability of characters, the production ability of movies, the promotion ability of extended products, or even the operation ability of theme parks. There will be a huge leap, and our Marvel universe will once again enter new members.
Third, Marvel Comics is extremely rich in universe-related products.
There is a saying that "having money is willful". In fact, after the acquisition, Disney will become a typical "deep pockets", and it is also the "deep pockets" of various products. Not only in the Marvel universe, but also in the copyright of related products.
For example, all copyrights of the Star Wars series will be owned by Disney, which will give it greater power and freedom to develop more movies, televisions, derivatives and so on. Such a good growth will certainly promote the development of Marvel Universe.
