|This article is about a/an evil mecha in Choudenshi Bioman.|
It has two mounted cannons on its shoulders, a gun on the right arm, and a hidden head that can fire a beam weapon from the eye called the Body Cannon.
Cannon Megas was one of multiple Neo Mecha-Gigan in dock at Neograd awaiting to be used by Gear before it is stolen by the newly-arrived Silva, who took the vehicle to escape Gear's forces while searching for his own personal mecha, Balzion. The Bio assassin uses the mecha to attack Bio Robo and the Gear forces until he decides to confront the Bioman personally detecting the Bio Particles within them. Using the opportunity, Mason retakes the Neo Mecha-Gigan from Silva and later tries to use it against Bioman; but the team is able to disable its weapons under the Gear warrior's control before finishing it off with the Bio Particle Cut.
