The Big Cannon (ビッグキャノン Biggu Kyanon) is the personal weapon of the Maximal commander Big Convoy. It is extremely powerful; only the likes of Magmatron could remain functional after even an indirect blast.

By inserting his Energon Matrix into the cannon, Big Convoy can transform it into the Matrix Buster (マトリックスバスター Matorikkusu Basutā). Fueled by this link to the supercomputer Vector Sigma, this weapon is so powerful, even a god might pause when faced with it.

Beast Wars Big Convoy comes with a spring-loaded Big Cannon which can fire two missiles from its two barrels in succession with a rotating dial. Forming the trunk, back, and tail of his mammoth mode, it can be deployed by pulling the entire assembly up, rotating it all the way around, and rearranging his numerous kibbly panels, with the trunk facing backwards, and the cannon facing forward. This rather large accessory ends up on his back in robot mode, and can be detached and transformed for use as a hand-held weapon, although its large mass can make Big Convoy's arms flop down when held.

This mold was redecoed into Beast Wars Black Big Convoy's cannon, Universe Nemesis Prime's cannon, Timelines Ultra Mammoth's Blue Bolts cannon, and Legends Blue Big Convoy's cannon.

Notes

• According to the events in the story "Mortal Combat! Twenty Thousand Meters in the Sky" from the Beast Wars Neo manga, the Big Cannon seems to be a part of Big Convoy rather just a weapon.
