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 throw his opponents this time around and can no longer block attacks), now being able to use his spin kick multiple times in a row after powering up.
- 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).
