A boxer fly is an enemy in the 1999 video game Bugdom. There is only one boxer fly in the first level, but several in the second. They pack a good punch that sends Rolly flying, but it only takes one hit to knock them out. Boxer Flies either patrol on set paths or wait in place for Rolly to come close before they strike. When they fly close to Rolly that means they are about to punch. Avoid this maneuver by stepping to the side and kicking the enemy once. They can chase you in the water so don't try to evade them there.
