Pauley is the Second Grade President at Gallagher Elementary School. As shown in Operation: S.C.I.E.N.C.E., he might be a KND-operative (presumably for Sector H), but if he is, it's never revealed what his codename is.
In Operation: E.L.E.C.T.I.O.N.S., Pauley and the other Grade Leaders are forced to make an alliance with the Fourth Grade by the Delightful Children. Pauley leads his grade in the assault against Hendry Middle School. He, Jesse, and their female friend make it inside the school, but Pauley is taken out by a Water Cannon.
Pauley speaks with a very nasally voice. He doesn't show fear in the face of danger, as he was determined to keep pedaling through Hendry Middle School, even after his friend, Jesse was taken down.
