Avengers: Infinity War is set to bring the superhero thunder in a big way, with so many of Marvel’s heroes expected to show up that they’ll actually have to cut people just to have room (not to mention that we still don’t really know what the roster is going to look like). While the superhero stable is far from set, it’s a safe bet that most of the big players (or at least a good chunk of them) will be present and accounted for in Infinity War. When it comes to the villain side of the equation though, things get a bit more muddled. We know that the Mad Titan Thanos will be the main threat, but is he going to recruit anyone else in his war on Earth and its mightiest heroes?
Since Infinity War will be split into two films, there’s a lot of room for Marvel to include plenty of additional villains to keep our heroes engaged, which will also offer a build up of sorts to the final confrontation with Thanos. Which villains will those be? We already know that Magus AKA Adam Warlock will make an appearance, but Marvel really can’t go wrong with including any (or all) of the following:
One of Doctor Strange’s greatest arch-nemeses, Dormammu is rumored to make an appearance in the Sorcerer Supreme’s solo movie this November. The lord of the realm of darkness, Dormammu is one of the most powerful villains in the Marvel universe and while we probably wouldn’t see him ally himself with Thanos, he could make an appearance as a challenger to the Mad Titan’s galaxy-conquering schemes. After all, Dormammu has his own plans for domination, so he’s not going to sit idly by and let Thanos do as he pleases. This could lead to an actual showdown between the two villains, with Thanos probably coming away victorious, but it seems more likely that Marvel would use Dormammu in a cameo capacity so as to not distract too heavily from Thanos being the main villain.http://marvel.wikia.com/wiki/Dormammu_(Earth-616) Source: Marvel Wikia
