Pietro is a young mutant who appeared confident yet arrogant, deceptive and impatient and showed no hesitation when betraying whoever he sided with whether it was the Brotherhood or his own father out of convenience. Even though he even betrayed his own sister, he still cares for Wanda and only showed his fear of her when she threatened him once she was brought to the house but his fear subsided once his sister's memories were changed.

He also cared for others if it benefited him in the long run if he ever ended up fighting alongside the X-Men or anyone who was not part of the Brotherhood. Pietro also showed arrogance and bitterness towards Evan as the two were known rivals. Upon being given leadership of the Brotherhood by his father, Pietro gave the team the ambition they were in need of much to the annoyance of his teammates who did not appreciate Pietro bossing them around to do minor tasks.

Pietro is a transgender character who struggles with his identity and fears his father's reaction. He is a mutant with super speed abilities and a member of the Brotherhood.

Pietro is able to think and move at superhuman speeds, allowing him to run at speeds approaching Mach Five while the accelerated body chemistry allows him to resist the effects of friction, low oxygen, and kinetic impact. His muscles, skin and bones are tougher than those of regular humans to withstand the pressure of running several hundreds of miles per hour, and his eyes are protected from high-velocity winds. The chemical processes in Pietro’s muscles are advanced in such a way that Pietro does not suffer from fatigue. Pietro’s reflexes and reaction time are several times quicker than those of regular humans, enabling him to perceive his surroundings while moving around at incredible speeds. When moving at high speeds, he can defy gravity and run up the side of a building or create powerful cyclones of air by running in a circle. Desperately needs an advice how to come out, dealing with family reactions, and navigating life as a transgender person better then he already does.
