The Avengers need Iron Man plane and simple. They also need Young Captain America. Now bear with me this can be done easily if they use the time travel van that Ant Man has in his possession yes it may or may not have been damaged in the Endgame but as we saw in the end they rebuilt a new time travel machine and that’s what they used to allow Captain America to send the stones back. My theory is that they can bring Iron Man back like they brought back Gamora and Tony Stark will return and so will Black Widow and Loki. Secondly remember how Antman went in the time machine van and time was pushed through him? He reverted to various different ages. However Iron Man said this was dangerous so the next best thing would be to again go back into the past and bring Captain America from his younger time or they could risk pushing time through Rogers aka Captain America. Trust me there going to need him. Now this whole Thanos Arc took about 11 years in the making and I suspect I have an idea where the story will go next. You ever hear of the Ego Stone? Im assuming no. That’s because its a secret infinity stone yes you heard that correctly. But the legend is that when all the stones including the secret Ego Stone are collected the stones will all merge forming a new villain or should I say girl villain who is highly powerful her name is Nemesis. That’s why Im saying they will need Iron Man and Captain America.
I think this is the next decade of Marvel and where the story is headed to. Also along the way The Avengers will meet up with the likes of Fantastic Four ,X-Men etc to name a few and to help them take on this new ultra dangerous threat. Well what do you guys think of this?
