Wanda Maximoff (Scarlet Witch)

Wanda was born in 1989 in the Eastern European country of Sokovia, along with her twin brother, Pietro. Their parents were Olek and Irina Maximoff. As children, Wanda's parents died during the bombing of Sokovia, but the children survived thanks to Wanda's magic.
Later, the twins voluntarily submitted to experiments by the criminal organization Hydra. Under the influence of Loki's Scepter, which contained the Mind Stone, Wanda developed supernatural abilities: telekinesis and energy manipulation.
Tragedy and emotional instability. Having lost her parents and brother, endured the death of Vision, and fallen apart after Thanos's snap, Wanda was deeply traumatized. This left her vulnerable to manipulation and led to a loss of control over her powers.
Anger and a thirst for revenge. Hatred for Tony Stark, whom she believed was responsible for the destruction of her country, drove her to radical steps—consenting to experiments, allying with Ultron. After Pietro's death, she was ready to destroy Ultron's main body to exact revenge.
Selflessness and courage. Despite her injuries, Wanda demonstrated courage. For example, during the Battle of Sokovia, she helped protect civilians and fought alongside the Avengers.
