While there was an original iteration of Heroes Reborn, the most recent variation is the one that could have the most impact on the MCU. Phil Coulson made a deal with the devil, with Mephisto changing reality itself to reflect the false heroes of the Squadron Supreme.
The Squadron has been heavily rumored to appear in the Multiverse for the MCU, so it might not be too much of a stretch to see a narrative that portrays them as the new heroes of Earth-616. The roster of characters and their copy-cat theatrics of the Justice League makes this a notable story for hardcore comic fans.
