He is characterized by his easily identifiable double chin and constant munching on Cheetos.
Keith appeared before the boys to tell them that someone had broken their record in Dig Dug. The boys asked him who "MADMAX" was, but he refused to say it, unless Mike Wheeler got him a date with his sister Nancy.
Keith makes a brief appearance at the end of The Battle of Starcourt. It is revealed that he is now the manager of the Family Video in Hawkins where he gives jobs to Steve (reluctantly) and Robin three months after the Starcourt Mall burned down.
Keith is an acquaintance of the boys, who often exchange childish jabs with each other.
Keith isn't conventionally attractive but tries pushing his luck trying to get Mike Wheeler to set him up on a date with Nancy, even going to the lengths of helping Lucas trick Max into getting in a room with him to inform her on the events of the previous year.
