So, we finally have Phase III all set-uo, but let's keep ignoring the present and focus on the more distant future, what are your expectations for Phase IV? I trust that Infinity War will mark the end of the Thanos storyline, what threat awaits the MCU next? For the films that open this new era in the franchise i vote for Iron Man 4 and a new Hulk movie, sort of like a paralel to 2008, when Iron Man 1 and TIH started this whole engine. As for the event closer threat, these are some of my candidates: 1. Kang He's one of the primary Avengers villains, considering we've going through Ultron and Thanos, i think he has high chances of being the next best foe for the heroes. Maybe he could be foreshadowed through Phase IV, building up his power. 2. World War Hulk One of the Phase starter films could be something like Planet Hulk, then by the end of the Phase he comes back to earth in order to get his revenge on the MCU's Illuminati. 3. Skrulls We don't know if Marvel Studios own their rights, or if Fox still has them, but they're powerful enough to serve as a good challenge, even in a post-Thano world. 4. The Liberators This may be a more difficult suggestion but it's possible, some time ago it was mentioned that The Avengers would take some inspiration from The Ultimates, so why wouldn't another one of the Avengers films take inspiration from The Ultimates 2? The Liberators wouldn't have to consist of the same members, in fact, they kind of seemed more like a modern version of the Masters of Evil. The idea could be interesting to have on film, as an answer to the USA using super people various nations decided to create their oun team and launch an attack on the USA 5. Return of an old enemy Someone like Ultron may return, more powerful than before, could form an interesting intergalactic challenge, in an universe still recovering from Thanos, now having to deal with this robot multiplying like a virus.
