Barbon first appears in the first stage's background, moving away when the player engages the mini-boss Electra. He is fought shortly after, in the bar's back alley, beginning the fight by ripping his shirt off and saying "Come on!"
He has no long range moves, but is a mid range type of opponent. His basics include punches, spin kick, and a quick snap kick. He has the ability to lift and throw players across the screen, more common in harder difficulties. He will often block when players fight too aggressively.
Later on in the game two pallete swaps of him named Wayne and Vulture will appear as mini-bosses in stages 5 and 8 respectively.
In Streets of Rage 4 Barbon fights in much the same manner as he did before. Though he no longer throws his opponents and no longer block attacks, he gains super armor while standing up and while doing his spinning kicks. After powering up, he'll use his spin kick multiple times in a row.
- In SOR2, Barbon wears a bartender uniform, while in SOR4, he wears a biker jacket instead (suggesting that he's the leader of the Red Demons MC).
- In the beta of Bare Knuckle II, he is the final boss.
