Benjamin James "Beast"  Diaz is the second youngest member of the Diaz family. Beast is a very mischievous boy. He is also the younger twin brother of Lewie Diaz.


He is very mischievous. 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. Beast also seems to love cotton candy. 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 is not as smart as 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.
