Final Fight 4 takes place after the events of Final Fight 3. Mike Haggar is still Mayor of Metro City, Cody and Guy are still around, Maki and Carlos now live in Metro City, and Lucia and Dean are working for the Metro City government. All is well until the Mad Gear and Skull Cross gangs join forces to take down Metro City for the very last time. And this time, it's personal. The Mad Gear and Skull Cross gangs have made propaganda posters depicting Haggar as the enemy. When this is broadcasted on live television, Haggar and the bunch spring into action to defeat the two gangs for the final time.
