Sometime in the past, Stanthony had accidentally splashed himself with Blue Paint, which corrupted him and turned him into the menacing boss, Big Blue.
Afterwards he assembled an army of Blues and Drabs under his leadership. It can be assumed that during this time, he and his army had went to the moon and built a base of operations there, as well as turning it into a prison. Much later, he had recruited the gargantuan BigBoi into his army, becoming one of his most loyal soldiers and presumably his right-hand man.
At an unknown period of time, he had his army invade and eventually take over Stick Pritchard, capturing every single person there and taking them to the moon. In that time, he then set his eyes on Slusher Tower and Wing, where the upcoming invasion there would cause a chain of events to begin.
After the defeat of BigBoi Prime, Big Blue decides to make one final stand against Standrew in the hopes of defeating him, but is beaten, causing the blue paint all over him to be removed through Standrew's punch. Helped up by Standrew, he escapes along with the Slush Fighters, the captured citizens and the surviving Blues to Galaxyrise, whereupon he thanks Standrew and his group for saving him and the rest, shaking hands with each other as a sign of peace and friendship.
Stanthony does not make an appearance in the second game. He is absent from the beginning cutscene despite it taking place directly after the end of the first game.
- With the release of Slush Tile Rush, Stanthony's fate is currently unknown.
- His real name within the series is unknown. "Stanthony" is simply a fan name for him and not his official name.
- He is the only known named character in the whole series not to be a civilian that is the color white.
