Sam has always been a little different from his peers. Kidnapping and manipulating various players. His first victim was Joey, aka Taurtis.
Kidnapping him at a young age. (Both being around 10-13 years old) and managing to manipulate a pair of players to give him their home before he managed to convince the admin of the server they resided on to grant him admin permissions. From there, he managed to eliminate his first player. Killing the former admin at around the age of 15. With the powers of almost a full fledged god, he took this opportunity to take full control of everyone of his players on the server. Rewriting their memories and infecting them with his own codes.
Sam played the careful, anxious, and nervous student well, a little too well, when he transformed the school into Akademi High School.
He invited new players to his server, random people he didn't even know (JTheStar, SirCutieYuki, SoulOwl, sookiesama, Grian, InvaderGaming, SillyJilly, DomRao, Einshine, Majo_Ellen, salexbrown, Gareth, and a ton more)... All victims for his grand plan. Once in his server that's where his fun began. Locking them in and individually locking their memories away of the other servers without even seeing them.
No seeing them was going to ruin his fun. He grew attached to some of the players, all short term though. Taurtis was always by his side and then it grew to Grian and Dom joining his side.
He wanted to have more than just that though. The high school scene grew tiresome, boring. He was easily annoyed by that boredom, when Taurtis got close to Salex and started dating her, he formulated a way to get rid of her. The second death at his hands but made to look like an accident. That was a short lived moment of fun, so he moved to manipulating the teacher, Gareth, into taking his own life. Bullying him, bringing up the fabricated wife who left him, one thing he didn't take into account was seeing the ghost. No that was new.
He was intrigued, wondering if he could recreate it. He had small moments where he would distract himself from these thoughts such as digging up Salex's corpse to steal her uniform to pose as a girl (Samantha) all to date Sookie who came out as a lesbian. He was found out though, which drove him to anger. Manipulating her to leaving a cryptic note on Salex's grave before... Vanishing without a trace. Not even her girlfriend Soul knew where she went. Her body never to be found.
Sam only has one goal in life. What can he do to make himself have the most fun? He found the enjoyment in watching people in pain.
It's why he forced Invader when they dated to eat the thing she was deathly allergic to so that he can stomach dating her (He never did like how she had PCOS, and how it gave her a beard. Something that seemingly disappeared when she ate her allergy.) Her pain was hilarious to him.
It's why he went on a murder spree at Akademi and the surrounding city on the server and manipulated the police into thinking it was someone else. Going into witness protection with Taurtis, Grian, and the remainder of his surviving classmates. Moving to a new city on the server called Tokyo.
Grian, and Taurtis ended up escaping from Sam by the end of this adventure... Being replaced with Einshine and briefly Gizzy. But they never could replace the two of them. No... They weren't the same. So he got rid of them much like he got rid of anyone who he didn't enjoy anymore.
By the time he had turned 18-20 years old... He was approached by The Watchers, interested in what he was doing, creating the most interesting stories without and inch of their powers with a deal, one he didn't jump to accept right away. He had everything he wanted. So they gave him an alternative deal. Make him one of them, but allow him to live as a player, a player who can seemingly never die. He accepted this, and thus The Watchers allowed the Rabbit hybrid to enjoy making the stories he wove, his way.
And so he brought in new victims after the big reset of his server.
