The Zeo Cannon was designed by Billy and Alpha in order to aid the Rangers. It is activated by inserting five power cells, each representative of each Zeo Ranger.
The Zeo Cannon is capable of firing a crygenic ray that can freeze the Machine Empire's monsters in their tracks. Among other components, it contains a chromium magnet. The Zeo Cannon is superior in firepower to the Zeo Blaster.
