Hivemind

Hivemind (real name unknown) is a serial killer, shapeshifter, and con artist who is the main villain of the Fancy Restaurant. They are said to be able to assume any identity they please, and have used this unexplained ability to commit numerous murders; the exact number is said to be in the thirties. They were apprehended, and reportedly stoop for good, upon the intervention of the Nesters.

Personality
Hivemind is a blank slate. Their very name alludes to their ability to trick even the most observant of investigators with false identities and false personalities. They are known to be cold, calculated, and callous, with a maligned drive to take lives seemingly at random.

In Fancy Restaurant, when Hivemind's new identity was unmasked, they revealed that they had grown sick and tired of the art of killing and were looking to leave it all behind. This culminated with their eventual surrender, being sent to jail (or to the spoon dimension, in some runs) to toil and rot for the rest of their life.

History
They first sprung up due to a spring of unsolved murders along an unspecified "East Coast" that were all linked due to a common series of circumstances. Hivemind was known to shoot their victims, and always do so under the cover of darkness in abandoned alleyways. At the scene of every crime, the exact same steampunk skull mask was left behind as a calling card to alert the police to Hivemind's guilt.

Hivemind would later "retire" from murdering, and settled down under what they hoped would be their final identity, operating as a building accountant/politician in the Nest's Fancy Restaurant. They let their guard down during the months they were employed at the restaurant, and were the target of a plot initiated by Chris Daughtry to murder them and prevent any future killing sprees. This plan backfired when Hivemind prevailed in a physical altercation with Daughtry, shooting him in the chest and leaving him to die.

Hivemind retreated back into the restaurant, employing a strategy that they had rarely used before, that being trying to get away with the murder. They cooperated with the investigation while hiding the truth about the incident, but eventually, that truth was uncovered by the Nesters and their allies. Hivemind surrendered, confessing to the crime. It would later be found that Hivemind's shot wasn't even the fatal blow that killed Daughtry, but that didn't matter in the grand scheme of it all. Hivemind hung their head and is purported to have abandoned their murderous ways, meaning that their reign of terror may finally be over for good.
