It's pretty clear who got the worst of the brutal Thanksgiving Day fight outside Halle Berry's house -- Gabriel Aubry is a  swollen, bruised mess after Halle's fiance Olivier Martinez  rocked him in the face.

Gabriel was photographed Friday in L.A., a day  after his violent showdown with Olivier put him in the hospital with a broken  rib and serious face contusions -- including one NASTY swollen  shiner.

Olivier clearly got the better of the fight, but still screwed up  his hand and his neck.
