MCU: 10 Cosmic Villains For Phase 4
8. The Revengers
The Revengers are a horrific mirror image of the Avengers from an alternate universe known as the Cancerverse, a universe in which life has entirely defeated death. In addition to this, the Cancerverse is infected by the corruption of one of the Many-Angled Ones, primordial entities that inhabit the space between realities.
This means whenever one of the Revengers is apparently killed, they return more horrific than before due to the union between their immortality and this Lovecraftian-type horror.
Thanos, in love with the concept of death in the comics, abhors the Cancerverse as his true love doesn’t exist there. Given the themes of cosmic horror this storyline explores it could be a great avenue to explore in the MCU with the Guardians or even Dr. Strange.
Although not part of the MCU, we've seen the X-Men off-shoot New Mutants turned into what looks like a horror movie, so cosmic horror would be a great step up. Kevin Feige recently mentioned MCU horror movies are possibilities. Additionally, if Thanos continues to be a major player in the MCU, he’d be an excellent addition to this story if Marvel want to explore his ties to Death in the future.
