Lewie Diaz is a main character in Stuck in the Middle. He is the older twin brother of Beast and the third youngest in the Diaz family of Diaz kids. He is known for being the mastermind behind his and Beast’s schemes.

Lewie is portrayed by Nicolas Bechtel.


Lewie is mischievous and always up to some shenanigans, usually with his twin brother, Beast. He mastermind behind all of their schemes; and the dominant twin who makes most of the decisions for Beast[1]. While both Lewie and Beast are childish because they're little kids, Lewie comes off as the more mature of the two. He is very dim-witted, but He is a lot more smarter than his twin brother Beast. Lewie is manipulative and likes to blackmail other siblings to get what he wants. Above all, Lewie is fun and adventurous, always coming up with games and activities that keep him and Beast occupied. Since they're always active, Harley uses Lewie and Beast as crash-test dummies for her inventions. They also love camping but usually get kicked out from camps for being too chaotic.


Lewie is the fifth-born child of Tom and Suzy Diaz. He is the older twin brother to Beast. His older siblings are Rachel, Georgie, Ethan and Harley. He is the older brother to Daphne Diaz.

In Stuck in the Beast-day Party, Lewie discovers that he and Beast were not actually born on the same day because he was born just before midnight while Beast was born just after midnight. So, he blackmails Harley to throw Beast a big birthday party to compensate for all the past years. This causes Harley to ask Beast to start making his own decisions which drives a wedge between the twins. But Beast later admits that he still needs Lewie.

Lewie attends Marshport Elementary School together with Beast and Daphne. When Lewie is not in school, he is usually leading Beast into some schemes, games or activities. Some of these include breaking rules on purpose by doing things that their mother told them not to[2][3]. Other times, it's different activities like treasure hunt, eating trash or pretending to be various things like firefighters, detectives among others.
