Jesus Samaras is based off of Greek footballer Georgios Samaras. He is called "Jesus Samaras" as his first name "Georgios" sounds similar to "Jesus". Edit
Jesus Samaras's first appearance on 442oons was in the Grease vs. Ivory Coats (then known as "Yayavory Coast") game in the 2014 FIFAIFOFUM 2014 World Cup. In this game, Jesus Samaras is awarded a last minute penalty, which he scores, sending Grease to the Round of 16 and Ivory Coats home.
He also appears in Mario Balotelli Racist Post where he tricks Not So Super Mario Balotelli into thinking he is the real Jesus.
