Earth-12 has a history that is much like Earth-616, with a number of important differences. In this reality, mutants in general, and super-heroes in particular are well regarded by humanity and are treated like celebrities, much like in the main DC Universe. Even beings such as the Hulk, who has appeared on the cover of Newstime, are regarded highly. Super-hero teams active in this reality include the Avengers, the Fantastic Four, and the X-Men. This reality also has its own version of the Brotherhood of Evil Mutants.
In this reality, Calvin Rankin was born a mutant with the power to mimic up to five mutant abilities at one time at a fraction of their power. He grew up with his father, a scientist with poor business sense. Living a life of poverty, he became a petty thief until the day his mutant powers manifested. They were triggered by his proximity to the original X-Men when they were in their civilian guises. Mimicking their abilities, Calvin became the costumed Mimic, and joined up with the Brotherhood of Evil Mutants. During the Brotherhoods subsequent clash with the X-Men, the group was defeated. The core members retreated, leaving the knocked out Mimic behind to be captured. In prison, he was offered the chance of being released by Charles Xavier if he agreed to join his School for Gifted Youngsters. Deciding it was better than prison, Calvin accepted the Professor's invitation and became an active member of the X-Men. Training with the group, he helped them master their abilities, and he soon become leader of the team over the more timid Cyclops. Calvin became a long standing member of the X-Men, seeing them through many tragedies and triumphs. Calvin also opened his own chain of record stores, wrote a book, and ran a charity with fellow X-Man Warren Worthington.
Mimic was plucked out of his reality by the Timebreakers to be one of the founding members of the reality jumping Exiles, a team gathered to fix damaged realities. Mimic became a long standing member of the group, at one point being their leader. He ultimately died at the hands of Earth-58163's Proteus. His body was returned to his home reality by his teammate and lover Blink. During the funeral service, Blink was offered a membership in this world's X-Men. With her job with the Exiles unfinished she politely declined.
The rosters of leading super-hero and villain teams are different in this reality, most notably those of the X-Men and Brotherhood of Evil Mutants. The original roster of the Brotherhood consisted of Quicksilver, his sister Scarlet Witch, Toad, the Blob and Mimic. Mimic soon left the Brotherhood to join the X-Men. Whether the Brotherhood is still together is unknown.
The X-Men have had a number of different rosters over the years. Much like on Earth-616, the original roster of the team consisted of Cyclops, Iceman, Beast, Angel, Marvel Girl, and Professor X. Another roster consisted of Storm, Mimic, Cyclops, Shadowcat, Gambit, Colossus, Nightcrawler, Wolverine and an unidentified female mutant. At one point Bishop was a member of the team. The most recent known roster included Cyclops, Marvel Girl, Storm, Wolverine, Nightcrawler, Gambit and Colossus.
This reality is also home to a group of Morlocks, however their roster is unknown at this time.
In this reality Reed Richards obtained invisibility powers instead of his stretching regular powers.
In this reality Susan Storm mostly obtained stretching powers instead of her invisibility regular powers.
Aesthetic differences are common in this reality, especially in terms of super-hero costumes. The Fantastic Four, and many members of the X-Men wear costumes that are slightly or entirely different in style to their Earth-616 counterparts. For example, the Storm of this reality currently sports a Mohawk hairstyle, and the Iron Man of this reality wears a unique suit of armor.
