Sonic Cannon is a series of weapons used by Pied Piper's henchmen.
In 2015, Pied Piper's henchmen fought The Flash and Roderick Smith tried to attack him with a blast from the cannon. However, The Flash threw a lightning bolt, and it merged with the sonic blast which caused Smith's body molecules to turn unstable.
