Sam Temple is the main protagonist of the series. He is one of the four avatars Astrid sees in Little Pete's game. His avatar is a guy pointing a single palm into the air, with a ball of light.

Sam is of medium build with tanned skin, has brown hair and streaks of blonde, has sky blue eyes and is described as being quite handsome. Sam is also described as being happy-go-lucky. Before the FAYZ, Sam lived in Perdido Beach with his mother. Sam does not like his home, especially his bedroom. He remained under the social radar at school, not belonging to any clique, and having only one true friend, Quinn.

Sam first realizes he has the Power when he accidently burns off his stepfather's hand, because he thought his step-father was going to hurt his mother. This leads to the divorce of his mother and step-father. The identity of Sam's biological father remains a mystery. His birth certificate says that his father's name is Taegen Smith. Caine is also his fraternal twin brother.

Sam is known as "School Bus Sam" to the kids at school. This is because of an event when he was in the seventh grade. After the driver of the bus had a heart attack, Sam  takes control over the bus and saves the lives of other kids by driving the bus safely to the side of the road. This is what leads to Sam becoming the leader among the townies while in the FAYZ, but when Caine Soren comes to town, some lose their loyalty.
