Sonic Wave

Sonic Wave is the weapon Mega Man obtains after defeating Sonic Man in the DOS Mega Man game. It shoots small, fast moving sound waves that bounce off walls much like Gemini Laser. It can open a wall in Volt Man's stage.

Trivia

 * Sonic Wave is one of the only two sound based weapons, the other being Shade Man's Noise Crush. Both weapons bounce off of walls, though Noise Crush does this in a different way than the Sonic Wave does.
