Dominic Petros (Earth-21399)

Early Life
Dominic "Dom" Petros was born in Greece during the reign of Georgios Papadopolous's military junta. His parents fled the country for fear of political persecution, ultimately settling down in Boston. Here, Dom lived a relatively normal life, and eventually became a police officer after completing his service in the Army.

Unlike most mutants, Dom was a "late bloomer", his powers not manifesting until well into his adulthood.

Mutation Revealed
After the existence of mutants became public knowledge, Boston saw an uptick in hate crimes against them, which Dom came to experience firsthand. When responding to a 911 call in his beat, Dom witnessed a pair of other officers beating a squirrel-like mutant to near-death. Dom's intervention saved the mutant's life, but unfortunately, no charges were pressed since the chief of police was an anti-mutant bigot who sided with the offending officers.

Dom was outraged, and returned to the offending officers' precinct to confront them about their misconduct. In the course of their encounter, a group of other anti-mutant officers ganged up on Dom, forcing him to the ground and beating him for being a mutant sympathizer. This awakened Dom's long-dormant mutant powers, and in his rage he destroyed the precinct with a massive earthquake.

Dom survived the incident, but the offending officers did not. Now that Dom knew he was a mutant, and that the world knew, he feared for his life and went into hiding in rural Pennsylvania. In truth, he really did sympathize with mutants, knowing his parents experienced similar problems back in Greece. However, Dom was so terrified of his own power and of hurting anyone else that he isolated himself and swore off getting involved in the mutant rights movement.

Joining the Brotherhood
At some point, Dom was approached in his isolated, abandoned barn hideout by a man named Erik Lehnsherr. Erik told Dom about the rising political power of US Senator Robert Kelly, who was proposing legislation that required mutants to register their identities and powers to a government database. Dom initially refused to get involved, but Erik responded by appealing to Dom's past as a child of people who were persecuted for their beliefs, and their mutual status as people persecuted for what they are.

Eventually, Erik convinced Dom that he was faced with a similar situation in the anti-mutant hysteria, and gave him a choice: flee for a place that was little better for him, like his parents did, or join Erik's fight to overthrow the oppressive authorities. Dom ultimately chose to join Erik, and became a member of the Brotherhood of Mutants.
