Rex is shawns half brother. Unlike shawn (who satan had a child with an angel) Rex was born with two devils for parents. He went insane after reading to many creepypasta wiki stories, which corrupted his child hood memories. Sadly to say now all rex wants is the love of his parents, by killing his brother, leaving only one son left to love... But sadly Rex was killed after he kidnapped somone when shawn saved the people, rex chased after him only to trip and fall into toxic waste.
-Rex is full demon unlike peanut and shawn-After shawn killed peanut, her and rex got married in hell -Rex is in the sinister group of evil, along with ricksaw, white pantsman, anti blaze, and hackman.
