Paul Gaillard is a member of the eight grade who wears glasses and dark blonde hair in Odd's style, and wears green clothes. He appears mostly as a background character, but can often be seen fleeing from a X.A.N.A. attack. Paul has a larger role in Attack of the Zombies, when he becomes possesed by X.A.N.A. He is usually mild-mannered, quiet, and studious, but when something weird happens he often reacts in extreme fashion, such as in Plagued when the lights in the Cafeteria went out, and he can be seen atop a table, hollering like crazy.
He is one of the five children that got embraced by Jim in The Lake (he was comforting them by saying that he would protect them from the "monster"). He also hugged Jim around the waist as well. Like most minor characters, he gained no new outfit in Season 4.
