Scarlet Witch

"'But everyone's story begins once upon a time...and it's up to us to cherish the time we're given to ensure we live happily ever after.'"

Summary
Scarlet Witch is a powerful reality warper and magic user, originally a mutant, whose father was Magneto, but later retconned into an experiment conducted by the High Evolutionary.

In the beginning, Wanda was able to shoot so called 'hexes' and cause improbable and impossible things to occur in her surroundings, like collapsing ceilings, cutting wires, creating thunderstorms etc. With time, she gradually got stronger, and was made aware that she is able to wield 'Chaos Magic', powerful and almost unknown type of magic originating from the banished Elder God Chthon, who 'blessed' her when she was a child. Chaos Magic allowed her to achieve various mystical effects, and in order to control it, she was tutored by Agatha Harkness, centuries old witch and an experienced magic user.

In the meantime, she fell in love with a synthezoid, Vision, and got married to him. Despite him being a non-organic entity, the couple managed to get children, with Wanda 'willing' them into existence through her magic. However, when her children were born and some time after, it was revealed that the two boys, Tommy and Billy, were only shards of the demon Mephisto. The latter reabsorbed them some time after their birth, and in order to ease Wanda's pain, her mentor, Agatha, cast a spell on her and made her forget about this incident. And thus, Wanda forgot she ever had children, and even broke up with Vision.

With each moment, Wanda's powers grew stronger. Years after the incident, Wasp accidentally reveals to Wanda that she had children. Wasp quickly tries to deny it, but Wanda gradually remembered the past. Silently, she left the Avengers Mansion and went to Agatha Harkness' place. Not much is known about her whereabouts during this time, but it is known that she went crazy and lost control over her powers, killed Agatha Harkness, and later on created the infamous House of M reality, one of the most impactful moments in Marvel history.

In this House of M reality, Wanda was a princess, while Magneto was the king and the ruler of Earth. Namely, using her immense reality warping powers, Wanda created a universe where everyone would get whatever they want, a utopia. Or at least it seemed like it for her. Later on, Wolverine reveals that he remembers the past universe and tries to make allies with other people and marches onto the royal palace, in hope to somehow pursuade Wanda into changing things back to normal. The culmination of House of M occurs when Magneto kills Wanda's brother, Quicksilver, whom she resurrects quickly afterwards. Moments later, she utters three infamous words that changed Marvel Multiverse forever, "No more mutants". In an instant, the world turns white. The universe is reverted back to Earth-616, but the consequences of Wanda's spell were felt throughout the multiverse. Nearly all mutants lost their powers, and some subsequently died because of it. Mutants would continue to be an endangered species, until Avengers vs X-Men, a storyline where an angry Phoenix Force arrives on Earth in order to revert the actions done in HoM. By the end of the storyline, Wanda and Hope Summers wish away the Phoenix Force from existence, and reverse the 'No more mutants' spell.

Despite this, Wanda is still considered an enemy of the mutant race. After AvX, Wanda was a part of the Avengers, briefly and had a solo series run, where we find out more about her past.

Key: Base Scarlet Witch | House of M | House of Ideas Connection

'Please note that "House of M" Scarlet Witch is Wanda utilizing the full potential of her Chaos Magic. While it was originally written that she was amped with an external source of power called the Life Force, it was retconned into M-Day being the cause of Wanda's Chaos Magic rewriting the rules of reality.'
