8 Major Theories For Guardians Of The Galaxy Vol 3
1. Adam Warlock Will Be The Villain (Kind Of)
Guardians of the Galaxy Volume 2 had no fewer than five mid or post credit scenes, and set up several potential storylines for the future. Kraglin took up Yondu's arrow, the old school Guardians from the comics came together, and most importantly, Adam Warlock's long-awaited entrance into the franchise was teased.
After the Sovereign were defeated, Ayesha planned vengeance on the Guardians with a being created and engineered to be the perfect specimen. Adam. From this it is not too much of a jump to conclude the team will be facing Warlock in Volume 3, however it may not be quite so simple as that.
In the source material, Adam Warlock is nothing short of a hero, most notable perhaps for taking charge in the fight against Thanos and even having the strength to wield the infinity gauntlet himself. However, there is more than one side to the character. Adam's alter ego, The Magus, turned out to be a villain so powerful, it forced the Avengers to team up with the Mad Titan in order to put a stop to him.
It would make sense then to have Adam's evil counterpart be the one to take a stand against the Guardians, before Warlock appears to essentially save the world from himself.
