History
The past history of Loki of Earth-7812 mirrors that of his Earth-616 counterpart until the day of Bruce Banner's gamma bomb test. In this reality, it would be Rick Jones who would be bombarded with gamma rays and become the Hulk. When Loki would seek out the Hulk during a time when Bruce Banner had just finished creating a device to cure Rick of being the Hulk. Although the device would work, Loki's magic would insure that Rick would transform back into the Hulk once more.
Loki would them create an illusion of TNT on a railroad bridge to make the Hulk trash it, so he would take the blame and battle Loki's brother Thor. This would cause the gathering of the Hulk, Thor, Ant-Man, Wasp and Iron Man to form the Avengers. Although the details of Loki's conflict with the Avengers is mostly unrecorded, it has been stated by the Watcher that it ended in a similar manner as Loki's first clash with the Avengers of Earth-616.
Loki's subsequent activities are unknown.
