shy, meek boy, he has great leadership abilities when in the face of danger which are equal to T.J.'s. He is exceptionally skilled in dodgeball, once feared at another school as "El Diablo", however when he made a boy cry, he stopped playing it in shame. In this same episode, he shows he doesn’t care for marbles, either because of Dodgeball or dislike. Gus is both brave and swallows his pride when he addresses certain situations. Even though everyone sees him as a pushover, he has proven time and time again he won't be a pushover, but will remain meek. He stood up to Gelman (The School Bully) in “Gus’ Last Stand.” In Recess: All Growed Down, it was revealed that Gus had also attended Third Street for a few days as a kindergartener. He helped overthrow Randall’s manipulation of Mikey (who believed he was being taunted). This was confirmed by Finster apparently bearing a grudge towards him at the end of the film. Muriel P.

In a few of the series' episodes and in the film Recess: School's Out, she is revealed as having been attractive and popular when she was young but eventually became a strict, grouchy and fussy figure as she grew older. She becomes the gang's fifth grade teacher in the film Recess: Taking the Fifth Grade. In the film Recess: All Growed Down it is revealed that she was the gang's kindergarten teacher and she was pleasant but became hot-tempered and intimidating after seeing her kindergarten students all messy and having fun during recess. Principal Peter Prickly (voiced by Dabney Coleman): Principal Prickly is the principal of Third Street School. A former student at the school, he became a teacher out of a desire to help children and has been principal of Third Street since 1968. He is frequently
