I Don't really Know

Luther (Idk)

Sarah Henderson/NeedleMouse

"I remember that night. That night was unlike any other... It was to die for. I used to loathe that day, letting it destroy me from the inside out for thirty, long years. But I finally got my revenge. You are all mine now, whether you like it or not. I AM your god now."

She is a vengeful spirit who was accidentally murdered by her friends and had her death covered up for thirty years, during which she spent her time confined to the coding of Sega's games in complete agony. Filled with rage and bloodlust, she took the form of the company's mascot, Sonic the Hedgehog, and began hunting down her former friends so she can trap them in her eternal hell of suffering.

Biography- At some point in 1963, Sarah and Lily were invited to a party and she went to Luther to recruit him as there'd be a lot of people she wouldn't be familiar with and wanted Luther to be there in case anything went wrong in the 1960's when that was generally frowned upon. Luther agreed to go and brought along Michael and Martin. However, during the party, the group got drunk and got into a physical altercation, resulting in someone accidentally killing Sarah by accident, likely by smashing some kind of object over her head. The group, in their panic, moved Sarah's body from the location and tossed it in a nearby lake, promising to never speak about the incident again and take the story to their graves. Eventually, Sarah was registered as a missing person, with flyers being plastered around town as her friends, family and sister looked for her.

Soon after dying, Sarah woke up in what appeared to be a black void, confused on where she was until all the memories of the previous night came flooding back. Although she felt betrayed by her friends not helping, she came to believe they would remember her, before eventually losing hope and believing they hated her. Declaring revenge against them, Sarah swore that if she couldn't go home, neither would they, and spent decades waiting in limbo for her to gain some form of access to the mortal realm once again.

At some point, the video game company SEGA constructed one of their buildings over the lake where Sarah's corpse was buried. Sarah was eventually able to find her way into the code and took on the form of the company's mascot, Sonic the Hedgehog. Although she was one step closer to completing her plan, she was still tormented by memories of the night she was murdered, feeling how it felt to be killed over and over again.

Personality- Aside from the occasional drunken ramblings where she was mean and harsh, Sarah was generally well-liked and appreciated for her bubbly, relaxed and carefree nature.

Upon her death, Sarah became an entity filled to the brim with nothing but rage and hatred for the people who caused her death and covered it up. She has been shown to be extremely aggressive and vengeful, being hellbent on wiping out her friends and making them suffer as she had, unwilling to let go of what happened regardless if they felt guilty or not.

Needlemouse is particularly sadistic, openly admitting to have only been toying with Martin just to scare him, and her goal of killing her friends would also extend to bringing them into her world where she could make them feel the pain of everlasting death as she has. Needlemouse is also highly intelligent and skilled at manipulating situations to her advantage, having pretended to want to reach out and reconcile with Luther initially. She is also not above threatening the lives of her enemies' loved ones to get what she wants.

However, Needlemouse is also quite arrogant. As the controller of her video game world, she sees herself as its god and believes she's entitled to do whatever she wants to its inhabitants because of how she was wronged in the past, which also shows how delusional she is, believing her murders of her former friends to be an act of justice and completely fair considering how they essentially took her from her family, despite also doing the same thing to them.
