Beast Diaz is a main character in Stuck in the Middle. He is the younger twin brother of Lewie and the second-youngest member in the Diaz family of seven kids. He is known for his mischief and shenanigans with Lewie.
Beast is portrayed by Malachi Barton.
Beast is a very mischievous boy. He is always up for a challenge, even if he has no idea what it is, due to the fact that he has no common sense, but he is very determined and will always try to complete what he starts. He's slightly more obnoxious than his brother Lewie. He is shown to be gross at some times as seen in Stuck in the Mother's Day Gift, when he volunteered to use the bathroom mat in substitute for toilet paper when they ran out. He also doesn't not flush the toilet. He is a lot more dim-witted than Lewie as shown in the show because he never knows what to do and asks Lewie for advice and what to say or think and never does it for himself. Beast likes to have fun even if it gets him in trouble. Due to their hyperactive nature, Beast (and Lewie) are often used by Harley as her crash-test dummies for her inventions. They also love camping although they end up causing chaos and getting kicked out from most of them.
Even though Beast is Lewie's twin, he was born a few minutes after midnight while Lewie was born before midnight, meaning that they were actually born on different days. Beast doesn't know this until Stuck in the Beast-day Party, after which he lets Lewie help plan for his party. Since Beast is easier to manipulate, Harley convinces him to cut Lewie out of the equation and plan the party that he wants. This drives a wedge between the twins. Eventually, Beast admits that he still needs Lewie.
Beast attends Marshport Elementary School with Lewie and Daphne. When he is not in school, Beast is usually playing or running some sort of a scheme with Lewie. He and Beast are always active with games and other activities such as searching for treasure, eating trash and playing detectives.
