If Mega Man uses the Power Gear alongside Bounce Ball, he'll fire 3 extra balls behind him, making for a total of 6 balls per shot.
Like all of the special weapons in the game, Bounce Ball gives Mega Man new Head Gear & Arm Gear that alters his physical appearance when equipped, rather than just being a color swap. In this case, the Head Gear is a new helmet with several white orbs embedded into it similar to the ones embedded in Bounce Man's body, and the Arm Gear is a slightly bigger buster in the form a ball, similar in design to Bounce Man's feet. He also changes to a magenta color, just like Bounce Man.
- Bounce Ball's functionality, when enhanced by the Power Gear, makes it similar to Wild Coil, which also launches projectiles both behind & in front of Mega Man, though Wild Coil does this by default.
- The fact that Bounce Ball's projectiles rebound off of things also makes it somewhat similar to Rebound Striker, except Bounce Ball shoots 3 projectiles instead of just 1 & it doesn't rack up more damage the more it rebounds.
