The missing heroes

What is again very, very certain is that some heroes will skip the Civil War. The first one is Thor himself, who was last seen in Age of Ultron. Being the only Avenger who can finally find something out about the Infinity Stones and the villain who is out to get them, he went back to Asgard – so his next appearance will be in Thor: Ragnarok.
The other very notable absence is the Hulk. Last time we saw him was also in Age of Ultron, when he realized that he is too big a threat in order to remain part of the team. At the ending of the movie, it was said that his Quinjet crashed somewhere near Fiji. But the thing is that it was actually an open ending, since we don’t know whether Fury had any idea of his whereabouts or not – as it was later revealed, Hulk didn’t end there.
As everybody knows, Hulk is now on another planet, most likely transported there by Loki (or even Hela) – so he won’t get in the way of Thanos’ plans.
We could also mention the other heroes who aren’t present during the Civil War – the Guardians of the Galaxy. But, come on, nobody expected them to be there in the first place. The same goes for Doctor Strange, who will be introduced into the MCU (with his own origin story) later this year.
