A recurring character in the Gouketsuji Ichizoku series from Atlus.
Keith Wayne is a brash and egotistical youth who competes in the Gouketsuji tournaments and tends to flirt with pretty girls so he can date them. He also used to run in a gang, but due to the feelings of his father, he quit. In later entries, it's implied that he and Annie Hamilton are a couple.
His son is Chris Wayne, who was featured in Groove On Fight.
