10 Essential Marvel Villains Not Yet Used In The MCU
4. Magus
Magus is the evil alter ego of one of the most important characters from the Infinity Gauntlet storyline - Adam Warlock. While Warlock was created as the perfect being, Magus embodies all that he is not.
In the aftermath of Infinity Gauntlet, The Magus starts the Infinity War, assembling the stones for himself, and even creating a clone of Thanos to be his No. 2. The threat of this villain wielding the gauntlet is so great, that The Avengers and Thanos had to put aside their differences and work together to bring him down.
Even Galactus helped the heroes, going with Gamora to visit the Living Tribunal seeking help in the fight. This isn't a task that is taken lightly.
With Warlock already teased to exist in the MCU, introducing the Magus along with him would be the most logical option, though with the recent news that Guardians Vol 3. has been indefinitely put on hold, it may be a while until we see the pair.
