Avengers: Age of Ultron is somewhat the weakest link the Avengers trilogy so far and we can understand why MCU may not want to bring the film as much as its 2012’s prequel. Still, it’s important for the MCU as did set up the Phase 3 and even contributed in setting up Avengers 4.
Even this year’s Infinity War referenced Avengers quite a lot but there were no major references made to Ultron. While many fans believe that it will be paid off in next year’s Avengers 4, we aren’t quite certain.
While we’re unsure whether Ultron could return as a villain in Avengers 4 even with the whole time travel theory, the possibility of his return has substantially increased, thanks to what Marvel is doing currently. The first issue of Captain Marvel prelude comic is out now and it has revealed what Maria Hill and Nick Fury have been up to throughout the events of Age of Ultron, Civil War and Infinity war.
While we know that Fury had been aiding Captain America since the Avengers broke apart, he has also been fighting against threats that were not on Avengers’ radar. The comic also recaps Age of Ultron, taking us to the moment when Fury took in the Helicarrier to aid the Avengers who were facing Ultron bots on a flying Sokovia.
Here, one Ultron flew into the Helicarrier and got speared into pieces by Nick Fury. Right here, you see Ultron’s eyes flickering as he depowers. This could actually hint at the return of Ultron. We know that Vision obliterated the last Ultron bot, but we also know that Ultron can transfer his consciousness through wireless mediums. This means that the “little flicker” on the Helicarrier could’ve meant an Ultron transmission.
Perhaps Ultron travelled through it and re-grew himself and he might just find his way in Avengers 4. We finally do need to see a pay-off to everything set up by Age of Ultron. Here’s what writers of the film have to say about the unexpectedness of Avengers 4:
“Christopher Markus – [Avengers 4] doesn’t do what you think it does. It is a different movie than you think it is…Also…[the deaths are] real. I just want to tell you it’s real, and the sooner you accept that, the sooner you will be able to move on to the next stage of grief.
Stephen McFeely – Put it this way, I think [Infinity War] is a fairly mature movie for a blockbuster. It’s got a lot of fun in it, obviously, but boy, it gets very mature. The second one is also mature. We’re going to own these choices, and hopefully surprise and delight you and get you invested. It’s by the same studio, the same filmmaking team. They were written at the same time, shot at the same time. They’re clearly connected, but they are definitely two different movies, one of which is dependent on what happened previous.”
