Gus Griswald is one of the main characters in Disney's Recess.
History
Gus was originally the newest member of the Recess gang until it was revealed in Recess: All Growed Down that he actually met the gang in kindergarden.
Personality
In the second part of the first episode, "The New Kid", Gus moves to town and starts attending Third Street School. Because his father is in the army, he and his family often have to move to different towns. He also lived there for a brief period of time when he was in kindergarten, but moved a day after starting school.
Gus is the shyest member of the gang, and often gets frightened easily. Because he is more naive and inexperienced, he sometimes messes up the plans made for the episode at times. Despite these qualities, he has been said to have the biggest heart out of everyone in the gang, and tries to get along with everyone, with mixed results. Despite being cowardly, he'll often stand up to anybody troubling him, which was shown when he was in kindergarten.
When he was in kindergarten, he met the other five members of the gang. He seemed to be the group "leader" at first, being more outgoing and excited as opposed to his personality years later. The first kid he befriended in the gang was T.J., and he was the one who gave him his nickname. Gus also showed the other kids that Mikey wasn't a bully; Randall was just trying to set him up. He then tells the other kids to stop acting so shy and start having fun like kindergarteners do, which introduces the characters' personalities they have in the show itself. After Randall tattles on him, he is put in the principal's office. This is the time when T.J. becomes the leader of the kids and has them work together to save Gus, and their plan worked. Gus moved the next day, and didn't come back until fourth grade. None of the kids seemed to remember him from kindergarten, however.
