The Brain is a minor character in the GradeAUnderA series. The first and last time we see him is in the 'My Brain vs My Body' episode.


He makes Grade sneeze and tear when he smells 'harmless pollen', then he don't give words to Grade to talk to a 'pretty tasty lady', he makes Grade die of hallegic attacks because of peanuts, then makes Grade get an F- on a test and he makes Grade laugh in inappropriate situations. And he has sent Grade to f*ck.
