Green Cannon Machine is a green android monster that had cannons in his fists and shoulder-mounted missile launchers.
The Magnavores were seeking Hillhurst Mansion's treasure as seen in "The Treasure of Hillhurst Mansion." To aid them, they summoned the Mean Green Cannon Machine to obstruct the Beetleborgs. The Beetleborgs did him in with their weapons.
This monster was re-released by Vexor during the "Curse of the Shadow Borg" saga episode "A Friend in Need", where he was one of the first victims of Drew's Thunder Stinger (before upgrading to Mega-Blue).
Drew mentions that he is from issue #99 of the Beetleborgs comics.
- The head of Green Cannon Machine was later re-colored and combined with a recolored and de-spiked body of Rocket-Man to form the Power Rangers Lost Galaxy monster Brunt.
