Steven Beckett

Steven Beckett (スティーブン・ベケット), better known as the Killer (殺人者), is a major antagonist in the first arc of Evershade;Gaiden.

The identical twin brother of Sean Beckett, Steven began being stalked by the entity known as Siege due to his brother's own experiences with it.

As a result, he ruthlessly hounded Sean, Matthew Morningstar, and Gabe Benson, believing that killing everybody connected to Siege would stop it from terrorizing him.

Upon murdering the vessels of the Majestic Others, he was confronted by Gabe before being killed by HYBRID.

Appearance
Steven sports messy brown hair and wears a dark gray t-shirt and dark jeans. He also wears black gloves, running shoes, and a black ski mask only covering his nose and mouth. Steven is also shown to wear eyeliner.

Personality
Steven was originally a normal person and always hung out with his twin brother Sean, and his friends. However, after he began to have night terrors caused by Siege, he was driven to the brink of insanity. After this, Steven becomes completely different from before, having no qualms in killing even his own brother, also displaying a selfish and sadistic personality.

Despite this, he is quite intelligent, able to navigate through difficult areas and able to pinpoint Zack's location with only one clue. He also tricked Matthew Morningstar into going to a place where Zack was roaming in, eventually leading to Matthew's death. Steven also displays a masochistic personality, laughing whenever he suffers great pain.

Early Life (1994-2017)
Steven is the identical twin brother of Sean, and growing up, the two always stuck together and hung out. Steven did not move out with Sean, instead choosing to stay in their hometown. However, Steven began to have visits from Siege, almost losing his sanity and going insane. Eventually, he became convinced that killing everyone connected to Siege would save him and was dead set on completing his mission.

Evershade;Gaiden (2018)
Steven moves to where Sean and his friends were and secretly follows them. Steven's first act was killing the members of the Majestic Seven. After this, he relentlessly attacks Matthew and the others. He then kills Dr. Murphy, a childhood doctor called in by Matthew. Finding Zack's current location, Steven lures Matthew to it, where Matthew is killed by Zack.

He then tries to kill Gabe, but is stopped by an unknown entity and is later found dead. Zack had already deduced that Steven was the killer due to his similarities to Sean. Upon Zack revealing Steven's dead body to Sean before fighting him, Sean confirms that the killer is in fact Steven.

Trivia

 * Although Steven himself was never in direct contact with Siege, he was still attacked by him shortly after Sean's first encounter with it. This shows that the victim's relatives would eventually be attacked by Siege if the original victim encountered it first.
 * With the previous statement being the case, Steven's efforts to kill everybody connected to Siege in order to save himself would eventually be for nothing as he would still be attacked anyways, regardless if Sean is dead or alive.
 * Alex Guy has admitted that he shoehorned Steven into the plot, improvising as the arc went on.
