Brodie is a member of Team Magma. He is known to disguise himself in order to get his goals accomplished. In Unfair-Weather Friends, Brodie disguised himself as Milli, a scientist at the Weather Institute who was supposed to be collecting data on Groudon. Team Aqua was trying to steal the data, and they had no idea that Milli was really Brodie in disguise. He revealed himself when Shelly threatened to harm Bart and the other scientists at the Institute. After revealing who he was, Brodie flew away with his jet pack.
Brodie also appeared in The Ribbon Cup Caper. This time, he disguised himself as various people, including Officer Jenny, in order to steal the Ribbon Cup for the Grand Festival. When confronted by the real Officer Jenny, Brodie willingly gave up the Ribbon Cup and flew away once again. He hasn't been seen since.
