"Deep in Earth’s future, the time-traveling conqueror Kang
came to find his excursions into time left him unfulfilled, and he decided to give up worldly conquests and meditate on the nature of time until the end of his days. Thus, he journeyed to Limbo, a dimension that exists outside the timestream itself and built a castle, lording over the wanders of Limbo, the Space Phantoms
. At some point after this, Immortus was contacted by the trinity of beings known as the Time-Keepers
to oversee the 80 millenia of their existence and keep humanity (and especially the hero team known as the Avengers
) from expanding into space-- a prospect of which would have disastrous prospects in nearly 50% of all the multiverse. Immortus acted as "custodian" of this timeline, and acted many times to influence events that keep humans from exploring space, all under the guise of embarking “on a number of campaigns to untangle the skein of timelines."
These early machinations included sending a Space Phantom to break up an early incarnation of the Avengers and helping the early version of the Masters of Evil
. During this last excursion, Immortus witnessed the bravery of Captain America
, which forever would allow him a grudging respect for the Avengers. Thus, instead of destroying the Avengers, Immortus would subversively shepherd them to his own ends, such as manipulating events so that Thor
would relinquish his hammer's time-travelling capabilities.
Immortus also set out so that the Scarlet Witch
would not conceive children (who have the potential to stand among the greatest forces of the universe.) Immortus helped to instigate the relationship between the Scarlet Witch and the Vision
, thinking that no children would be born of this union, and Immortus officiated the ceremony that married the two. When this tactic failed, Immortus investigated the origin of the children, and manipulated events to reveal that the children were in fact pieces of the demon Mephisto
's soul. Immortus also took the opportunity to influence the dismantling of the Vision's robotic body and mind. Immortus tried to stop the Scarlet Witch once and for all banishing her from reality, but was instead seemingly banished himself. Immortus was saved by the Time Keepers and re-instated as their custodian."
What I'm talking about is merging Immortus and his wanting to prevent half the multiverse from being destroyed with Thanos getting the Gauntlet, and the alternate future of the Guardians in the 31st century. What Thanos will do changes the future for Kang, and he becomes more of a force for good in this series than most versions of Kang.
