Agent G is a German Shepard with a red collar and a black fedora with a red middle.
In "Agee Ientee Diogee" he was requested by O.W.C.A. to fight Heinz Doofenshmirtz while Perry the Platypus was on vacation. However, he gets distracted and ends up fighting Dr. Not Sorry all over Danville. When he finished fighting Dr. Not Sorry he goes back to Perry's Lair and is complemented by Francis Monogram on "his" successful fight with Doofenshmirtz.
