|—"You're Everybody's Sidekick"|
Gregg is somewhat taller than K.O. but shorter than Enid, and they have a white beak, feathers, and legs. Gregg's attire is magenta shorts with matching knee-high boots and a teal sleeveless shirt. As seen in "Second First Date", Gregg is seen wearing a light teal eggshell and teal shoes.
Gregg has low self-esteem and gave up on any dreams of being a true hero. They loiter around the plaza with a group of delinquents. Gregg is kind of a hanger-on, and they mostly just squawk in support of whatever Red Action or Drupe say. They have a serious temptation for seeds and will do anything to get them.
