Editing Big Cannon

{{disambig2|the cannon that can be powered up by Big Convoy's Energon Matrix|cannon form of the Red Matrix|Matrix Buster}}
The '''Big Cannon''' (ビッグキャノン ''Biggu Kyanon'') is the personal weapon of the [[Maximal]] commander [[Big Convoy (BW)|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 [[Unicron|a god]] might pause when faced with it.

Despite being told only do to reconnaissance on a [[Predacon fortress planet]], Big Convoy decided to disregard [[Crow Convoy]]'s orders and rushed into it, blowing it up with the Big Cannon. {{storylink|The 5 Rookies}}

When Big Convoy was busy fighting [[Magmatron]] with his hands, the mammoth nose on the Big Cannon pulled its trigger and blasted Magmatron several times, badly wounding him. {{storylink|Mortal Combat! Twenty Thousand Meters in the Sky}}

In a battle against the Predacons on the planet [[Jörmungandr]], Big Convoy used the Big Cannon to blast [[Guiledart]] into pieces, angered that he had interrupted the duel between himself and [[Dead End (BW)|Dead End]] by ordering [[Saberback]] fire on them. However, the Big Cannon was lost at the last moment when Big Convoy tried to save [[Break]]. It was sucked into space along with [[Saberback]] and several other Predacons. Later when heading back to ''[[Gung Ho (BW)|Gung Ho]]'', Big Convoy was trouble about why he chose to save Break and let his Big Cannon go, unaware of the growing bond between him and his trainees. Break thought it was his fault making Big Convoy loose the weapon. {{storylink|A Battle Fought Alone}}

===2006 IDW ''Beast Wars'' continuity===
When [[Shokaract]] emerged from his tower on [[Cybertron (planet)|Cybertron]], Big Convoy transformed into cannon mode and fired at the mechanical crab. It proved to be ineffective and Big Convoy was destroyed in a blast from Shokaract in response. However, thanks to interference from a chronologically displaced Magmatron, Big Convoy's death was erased from the timeline. {{storylink|The Ascending issue 3|The Ascending #3}} Big Convoy later transformed into cannon mode in an all-out attack on Shokaract, who was nearing "ascension". {{storylink|The Ascending issue 4|The Ascending #4}}

:''[[Transformers: Beast Wars (Japanese toyline)#BWN|Beast Wars]]'' [[Big Convoy (BW)#Toys|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 [[Beast mode|mammoth mode]], it can be deployed by pulling the entire assembly up, rotating it all the way around, and rearranging his [[Shellformer|numerous]] [[Kibble|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 [[5 mm post|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, ''[[Transformers: Universe (2003 toyline)|Universe]]'' [[Nemesis Prime (Universe)#Toys|Nemesis Prime]]'s cannon, ''[[Transformers Timelines (toyline)|Timelines]]'' [[Ultra Magnus (G1)/toys#Timelines|Ultra Mammoth]]'s [[Blue Bolts (Timelines)|Blue Bolts]] cannon, and ''[[Transformers Legends (franchise)|Legends]]'' [[Blue Big Convoy#Legends|Blue Big Convoy]]'s cannon.

==Notes==
* According to the events in the story "Mortal Combat! Twenty Thousand Meters in the Sky" from the ''[[Super Lifeform Transformers: Beast Wars Neo (manga)|Beast Wars Neo]]'' manga, the Big Cannon seems to be a part of Big Convoy rather just a weapon.
