Earth-TRN852 was created when Phil Coulson sold his soul to Mephisto and obtained the Pandemonium Cube, a demonic artifact capable of warping reality.
The history of Earth-TRN852 is presumably similar to Earth-616's but with several notable differences. Some of these include:
- The Squadron Supreme of America were the supreme superhero team of Earth instead of the Avengers as the Avengers were never formed -Tony Stark never created the Iron Man Armor as he was never injured in a warzone -Carol Danvers was a pilot and never became a superhero -Captain America was never retrieved from the ice in the Arctic -The Hulk was exiled to the Negative Zone after his first rampage
Blade the Vampire Hunter found himself on Earth-TRN852 without explanation and discovered the various differences between it and Earth-616. After talking with Nighthawk and with Odinson, Blade decided to do something about this by reassembling the Avengers, starting with Captain America.
