Magus

Magus refers to several characters:
 * The first Magus is the future version of Adam Warlock that he was destined to be due to the intervention of the In-Betweener, Master Chaos, and Lord Order in an effort to make an Avatar of Life. He met his "demise" after Warlock's meddling from Thanos's time probe. During his tenure within the Guardians of the Galaxy, Warlock later re-applies the previously erased timeline to repair the universe damaged by the Terrigan Bomb, effectively making the future come at full circle. As Magus, Adam is killed by Lord Mar-Vell.


 * The second Magus is, instead, the evil side of Adam expunged during him holding the Infinity Gauntlet in an attempt to become a more logical being.
