Pietro Maximoff

Pietro Maximoff, was a native Sokovian mutant. While his sister received mental abilities, he acquired the ability to move at supersonic speeds and other physical features.

Death
While moving civillians out the way from Magneto's wrath, Pietro ended up being impaled by one of Magneto's stray shards of metal. Magneto blamed Wanda for his death, and this is one of his reasonings for his revenge against her.

Physical Appearance
He was a handsome, young man with a lean and athletic frame, crystal blue eyes, and naturally silver hair (due to his mutation). He preferred comfortable clothing such as hoodies, baseball shirts, jeans, and sneakers, other than that, he typically wore a lot of sportswear.

Personality
Pietro was a rather cocky, arrogant, impatient, tenacious, and quick-tempered person. These personality traits were likely a side effect of his super-speed, due to thinking and acting at a much faster rate than most. Despite this, Pietro had a desire to protect those he cared about. He put a lot of pressure on himself to protect the people he cared about. He also deeply cared for his sister and the two shared a deep bond though they occasionally bicker like normal siblings. He looked after his sister and relied on her for support, while also being fiercely loyal of her. He also shown that he was incredibly brave and quite intelligent despite being considered to be more brawny than brainy.

However, despite all of these good qualities, he did have a few more negative traits, mainly his difficulty controlling his anger. Pietro had been diagnosed with intermittent explosive disorder, which caused him to be incredibly impulsive (which can lead to irrationality and poor judgment), as well as possessing a quick temper that caused him to be eager for a fight when angered.

Despite this general improvement in Pietro's anger and personality in general, he was still prone to bouts of irrationality and violence in certain circumstances. Afterwards, however, would Pietro become so mortified by his behavior that he would dedicate himself to making up for it, and continued to try and demonstrate a much better sense of control over his emotions.

Mutant Abilities

 * Superhuman Speed: Maximoff has the ability to run at extremely high speeds due to his mutation. He is able to think, act, move and perceive in seconds or less, far faster than normal people could even perceive. As such, he can perceive the world as moving in slow motion, especially when he is moving at super speed, while all others can see of him as he uses his speed is a vibrating blur of motion. His power causes him to generate an aura of blue, white and transparent energy currents and mist-like shapes, much like fire or wind, leaving behind a trail of it as he runs. His abilities make him nigh unbeatable in battle, with his speed giving him the ability to generate extreme force and momentum, as he can hit harder than normal humans while moving at super speed. In his confrontation with the Brotherhood, he managed to avoid multiple attacks and took down Sabertooth in seconds. His maximum speed is Mach 4.
 * Extreme Force Generation: He has enhanced momentum, which allows him to enhance the force in his attacks, strikes, impacts, and collisions, often propelling objects or people several feet, that he uses to compensate for his average human strength. He is, therefore, able to match Sabertooth's far superior strength in their confrontation, allowing Pietro send the latter flying by colliding into him and knocking him to the floor with one punch while moving at super-speed. During the Attack of the Sentinels, Pietro used this ability again to dismantle numerous spider-like sentinels by colliding with them at great speeds. This force, however, is not enough to injure Juggernaut, who was barely affected by Pietro smashing into him at supersonic speeds. Pietro's aura seems to protect those he carries even though they lack his enhanced physiology. Pietro can move multiple people in an instant, without risking whiplash injury or damage caused by high-speed air friction.
 * Increased Metabolism: Pietro has a hyper-accelerated metabolic rate, enhancing his physicality and ability to move and act while also making him less able to be stunned by attacks or injuries, as he quickly recovered from the pain of being shot in the arm and could still act as if he were not injured.
 * Improved Thermal Homeostasis: Maximoff can function in a stable internal environment that requires constant monitoring and adjustments to his condition that changes constantly, meaning he can resist the effects of friction and temperature while moving at incredible speeds.
 * Accelerated Perception: Pietro's increased speed also augments his reaction time, allowing him to react to danger and events much faster than a normal human, to the point where he can catch bullets in mid-air. As a result, Pietro tends to see the world around him as if it were in slow motion, especially when he is moving at super speed. However, even with his enhanced reflexes, Pietro can still be caught by surprise.

Abilities

 * Pick-Pocketing/Theft: Using his mutant abilities, Pietro can easily and stealthily steal things without anyone being the wiser. He has stolen heart monitors, cell phones, frequency jammers, and keys/keycards to a variety of doors and vehicles.
 * Skilled Combatant: Pietro can infuse his super speed with physical combat, enabling him to fight at incredible speed. His attacks may cause more damage than normal due to gaining kinetic energy, and thus momentum, produced through the speed of each hit. With this simulated superhuman strength, he was able to send Sabretooth flying through the air with a single hand, and thereby repeat the process by continuously intercepting the launched target.
