Editing Fusion cannon

[[File:MTMtE Part3 ExtinctiontoallTraitors.jpg|upright=1.4|thumb|A release of lubricant is quite common when seeing this.]]
The '''fusion cannon''' is [[Megatron (G1)|Megatron]]'s signature weapon. It is attached to his right arm and is devastatingly powerful, as demonstrated by its sudden removal of [[Ironhide (G1)|Ironhide]]'s head. (It's at least as powerful as [[Fortress Maximus (G1)|Fortress Maximus]]'s [[:File:Fortmaxgiveshead.jpg|hands]] in comparison.) It strikes fear into the [[spark]]s of both the [[Autobot]]s and the [[Decepticon]]s, though this description and its actual destructive capacity seems strangely [[To sell toys|uneven]].

====Marvel ''G.I. Joe'' comic====
As part of an agreement with [[Cobra]], Megatron's body was rebuilt to resemble an [[Earth]]-design tank with his fusion cannon replaced by a [[rail gun]]. {{storylink|Realignments}}

===Generation 1 cartoon continuity===
====''The Transformers'' cartoon====
{{listen|Fusion Cannon Fire.ogg|Fusion cannon|Megatron's fusion cannon from the Generation 1 cartoon.|14 KB}}
During a battle with the Autobots and Decepticons the fusion cannon was fired twice, destroying an oil rig and trapping various Autobots and humans. It was then fired once more to ignite the [[oil]] and create an enormous conflagration {{storylink|More than Meets the Eye, Part 1}}

When the Decepticons invaded [[Sherman Dam]] the fusion cannon appeared again, and was fired into the roof. When the Autobots showed up, it was fired at [[Optimus Prime (G1)/Generation 1 cartoon continuity|Optimus Prime]] and the Autobots, but unlike the ceiling, they dodged the blast. A battle then ensued between Optimus Prime and Megatron on top of the dam, but the fusion cannon was missing at this point (Prime tackled Megatron, so maybe that's why), and Megatron was forced to use his [[energon mace]], instead. Fortunately, he got the cannon back by the time he returned to his base. {{storylink|More than Meets the Eye, Part 2}}

The fusion cannon once more came in handy when Megatron fired it to escape a collapsed [[Ruby crystal mines of Burma|ruby crystal mine in Burma.]] After the debacle at the mine, [[Starscream (G1)/Generation 1 cartoon continuity|Starscream]] got a little bit rebellious and tried to shoot Megatron. But deflected the blast with a force field projected from the fusion cannon, then blasted Starscream in the shoulder (causing no visible damage) to punish him. 

All this nonsense was leading to the Decepticons trying to escape Earth. They needed some rocket fuel, so the Autobots tried to trap them with a fake rocket base—but Megatron knew better and double-bluffed them. The fusion cannon was fired once at the Autobots' fake rocket base to make the double-bluff more convincing. It reappeared at the final battle outside the Decepticon space ship. Despite trying to blast Optimus Prime the fusion cannon was shot off Megatron's arm by Prime's combat deck. Megatron (seemingly) retrieved it before boarding his space cruiser. Starscream played up again, and Megatron put the cannon down to give Starscream a chance to prove himself, a chance that was foiled by [[Mirage (G1)|Mirage]]—so Megatron picked up the fusion cannon once more and used it to punish Starscream again before the space cruiser crashed. {{storylink|More than Meets the Eye, Part 3}}

So after that defeat the Decepticons didn't show up for a few months, when they did Megatron used his fusion cannon again in a battle against Optimus Prime at a solar energy plant, firing several times before being flipped by the fusion cannon by Prime! Megatron retaliated by punching Prime in the... uhh... gut, with the cannon. The Decepticons then took the energon they stole from the plant to the [[space bridge]]. [[Bumblebee (G1)/Generation 1 cartoon continuity|Bumblebee]] was spotted spying on them, and Megatron fired four times, missing on all four. He racked up even more misses in a later battle inside a cave where he fired no less than nine times and missed every single time. The cannon did manage to destroy a nice rock formation, though. {{storylink|Transport to Oblivion (episode)|Transport to Oblivion}}

When the Decepticons invaded a science lab to steal an anti-matter formula the Autobots tried to stop them and Megatron fired at the Autobots (and their [[hologram]]s) about six times, managing to destroy a floor and a wall, but no Autobots. The anti-matter formula was then used to power-up Megatron's gun mode, but not his fusion cannon. {{storylink|Roll for It}}

After Optimus Prime was injured the Decepticons pressed an attack on the Ark. Megatron fired his cannon six times during the battle, even managing to actually hit [[Sideswipe (G1)|Sideswipe]], blasting him out of the air. Optimus Prime (now repaired!) then showed up and the cannon shot him, rather ineffectually. It was then knocked off Megatron's arm and was useless for the rest of the battle. {{storylink|Divide and Conquer}}

At the [[Arctic|North Pole]] (or thereabouts), during another battle with Optimus Prime where the fusion cannon was used to shoot Optimus in the back it was once again knocked off. This time it was knocked off by a shard of crystal thrown by Prime. {{storylink|Fire in the Sky}}

Another day, another fight at a dam. This time Megatron hooked up his fusion cannon directly to the dam as a power source. He proclaimed that the Autobots would now witness the power of his fusion cannon (actually mentioning it by name) and blasted the side of a cliff face (which was weakened by [[Rumble (G1)|Rumble]]'s [[Earthquake (event)|earthquake]] powers), collapsing it and dumping the Autobots into the river. {{storylink|S.O.S. Dinobots}}

[[File:Brawnfusioncannon.jpg|thumb|left|Meet the Soldier]]
The fusion cannon's next job was blasting another hole, this time to create an entrance to a Mayan pyramid. It was then used at a battle to collect some gun-building materials where it became something of a football. First Megatron shot [[Brawn (G1)|Brawn]] in the chest, knocking the Autobot over. Then Brawn knocked the cannon off Megatron's arm and fired it himself hitting Megatron and knocking him over, but the kickback from the blast knocked Brawn over (again). Finally [[Laserbeak (G1)|Laserbeak]] retrieved the gun for Megatron and another shot was fired at Brawn, but no one had to fall down this time because the shot missed.

Back at the Mayan pyramid Megatron used the fusion cannon to cause a distraction for the Autobots by blasting a mountainside twice and causing an avalanche. {{storylink|Fire on the Mountain (episode)|Fire on the Mountain}}

Then there was the time Megatron tried to bring [[Cybertron (planet)|Cybertron]] to earth. Remember that? The fusion cannon was present throughout Megatron's machinations. But its most notable actions were during an Autobot invasion where a single underwater blast from the cannon enveloped Optimus Prime, [[Jazz (G1)/Generation 1 cartoon continuity|Jazz]], [[Ironhide (G1)/Generation 1 cartoon continuity|Ironhide]], [[Prowl (G1)#Generation 1 cartoon continuity|Prowl]], [[Wheeljack (G1)#Generation 1 cartoon continuity|Wheeljack]] and Bumblebee (but didn't kill any of them), repeated (about six) shots fired during a Decepticon attack on the ''Ark'' (one of which hit Prime in the back) and a single shot at the battle at Megatron's giant space bridge.{{storylink|The Ultimate Doom, Part 1}}

Megatron's environment-destroying plan saw the Decepticons getting trapped in their own base, so used the fusion cannon to blast yet another hole in a wall to escape. {{storylink|The Ultimate Doom, Part 2}} The subsequent fight at Megatron's energon transport ship also saw the fusion cannon fired, this time twice (didn't hit anything, though.){{storylink|The Ultimate Doom, Part 3}} Despite the energon ship exploding, neither Megatron nor the fusion cannon were destroyed and Megatron employed his signature gun again in a battle outside Archeville's lab. (This is the same battle where Megatron says, "I always hit what I aim for," which one has to assume at this stage is slight hyperbole.) {{storylink|Countdown to Extinction (episode)}}

During an incident with the [[Insecticon (G1)|Insecticons]] Megatron fired twice at the Autobots, then took his fusion cannon with him to an oil refinery where the Decepticons were collecting some energon. For whatever reason, Megatron took his cannon off and propped it against a wall while he was there, but fortunately he put it back on when the Autobots showed up. Fortunately because, without it, he couldn't have fired off two (unsuccessful) shots, then covered his retreat by using the fusion cannon to set fire to an [[oil tanker]]. {{storylink|A Plague of Insecticons}}

As we know, all Transformers (or at least Decepticons) get their special powers from [[power chip rectifier]]s, so when Megatron was preparing for a one-on-one duel with Optimus Prime he took the chips from all his fellow Decepticons into himself. During the duel this allowed him to fire cluster bombs from his fusion cannon; but Megatron still used what appeared to be three normal fusion cannon blasts to finish off Prime during the battle.{{storylink|Heavy Metal War}}

An attempted coup from [[Devastator (G1)|Devastator]] is another matter. The shots continuously bounced off his armor and Megatron had to resort to a 5-way fistfight with Starscream, [[Astrotrain (G1)|Astrotrain]], and [[Blitzwing (G1)|Blitzwing]] as an alternative. {{storylink|Triple Takeover}} By [[2005]], Megatron's fusion cannon was far more powerful than it was twenty years earlier in that was able to kill a ship-load of Autobots, including Ironhide. Megatron lost his fusion cannon in his final battle with Optimus Prime, and upon being reformatted by [[Unicron]] into [[Galvatron (G1)/Generation 1 cartoon continuity|Galvatron]], his fusion cannon was replaced by an arguably far more effective [[particle cannon]], which he promptly used to kill Starscream. {{storylink|The Transformers: The Movie}}

====''Wings Universe''====
{{Wingsnote}}
Megatron clone [[Megaplex]] brandished a fusion cannon as a secondary weapon. {{storylink|Termination}}

[[Squadron X]] survivors [[Ferak]] and [[Tornado]] escaped [[Torax Prime]] aboard a modified escape pod, refitting it with warp thrusters, proton bombs, and a small fusion cannon. The pod, however, was no match for the firepower of an Autobot [[Vanguard-class Deep Space Interceptor|Vanguard class]] fighter. {{storylink|Tornado - Decepticon Saboteur}}

===''Earthquake''===
Megatron's nuclear-charged fusion cannon was, as usual, the Decepticon leader's weapon of choice. In one notable scenario, Megatron turned the weapon on [[Soundwave (G1)|Soundwave]] and [[Starscream (G1)|Starscream]] when he discovered that they were plotting to overthrow him. {{storylink|Earthquake (book)|Earthquake}}
{{-}}

===''G.I. Joe vs. the Transformers''===
Having defeated Megatron, [[Optimus Prime (G1)|Optimus Prime]] ripped the fusion cannon from his arm and used it to destroy the [[SPS Satellite]]. It supposedly was the only thing the [[G.I. Joe (team)|G.I. Joe]], [[Cobra]], [[Autobot]], and [[Decepticon]] troops gathered at [[Cobra Island]] had that could reach something in space. Thereafter, the fusion cannon was brought to [[Area 52 (G1)|Area 52]]. {{storylink|G.I. Joe vs. the Transformers issue 6|G.I. Joe vs. the Transformers #6}}

===IDW Generation 1 continuity===
Megatron's first fusion cannon was a gift from [[Starscream (G1)/IDW Generation 1 continuity|Starscream]]. {{storylink|Megatron Origin issue 4|Megatron Origin #4}} It's ironic how [[Megatron (G1)/IDW Generation 1 continuity|Megatron]] decided to pay him back a few million years later by blowing a huge hole in his torso. {{storylink|Infiltration issue 6|Infiltration #6}} Whenever they met in combat, [[Optimus Prime (G1)/IDW Generation 1 continuity|Optimus Prime]] would ''always'' go for Megatron's cannon arm. {{storylink|Chaos Theory Part 1}} During their battle in [[Brasnya]], a well-aimed shot from Optimus destroyed Megatron's cannon. {{storylink|Escalation issue 5|Escalation #5}} During a showdown in [[New York City]], [[Optimus Prime (G1)/IDW Generation 1 continuity|Optimus Prime]] ripped the fusion cannon off Megatron's arm and beat him with it until it broke. {{storylink|All Hail Megatron issue 12|All Hail Megatron #12}} When he returned in a new body, Megatron had replaced his trademark cannon with a [[rail gun]]. {{storylink|Revenge of the Decepticons Part 5: Enemy Mine|Enemy Mine}} The change didn't last long, as he went back to the trusty ol' fusion cannon for his next body. {{storylink|Before the Dawn}} After Megatron surrendered and joined the Autobots, Optimus Prime had him destroy his fusion cannon as a symbol of giving up on the war by dissolving it in acid. {{storylink|slaughterhouse}} When he was presented with a new one in preparation for a last stand on [[Necroworld]], he rejected it. {{storylink|The Dying of the Light Part 4: At Close of Day|At Close of Day}} Upon learning that [[Fool's Energon]] was nothing more than a placebo and that he had been acting with subconscious self-imposed restraint, Megatron attached the weapon to his arm and entered the battlefield mowing down a large number of Decepticons but ordering his teammates to take the wounded [[Ravage (G1)/IDW Generation 1 continuity|Ravage]] back to [[Ratchet (G1)/IDW Generation 1 continuity|Ratchet]]. Megatron demanded Tarn come face him in battle but a well-placed shot by [[Nickel]] and [[Vos (DJD)|Vos]] destroyed the cannon leaving him defenseless. {{storylink|The Dying of the Light Part 5: Rage, Rage|Rage, Rage}} Despite this, Megatron kept the weapon attached to his arm even after the battle was over. When Ravage died, Megatron flew into a rage refusing to part with the destroyed cannon and even trying to use it to murder the Autobots. When [[Terminus (G1)|Terminus]] showed up however, Megatron detached the cannon without hesitation. {{storylink|The Dying of the Light Part 6: Do Not Go Gentle|Do Not Go Gentle}}

The fusion cannon had been made from the [[Censere|the Necrobot's]] teleport chamber. Following its destruction, [[Brainstorm (G1)/IDW Generation 1 continuity|Brainstorm]] turned it back into a teleport chamber. {{storylink|Dissolution Part 1: Some Other Cybertron|Some Other Cybertron}}

As leader of the [[Decepticon Justice Division]], [[Tarn (DJD)|Tarn]] sported a ''double'' fusion cannon. {{storylink|Rules of Disengagement (issue)|Rules of Disengagement}} In their final confrontation on [[Necroworld]], Megatron ripped the weapon off with ease, mocking Tarn for having two cannons. {{storylink|The Dying of the Light Part 6: Do Not Go Gentle|Do Not Go Gentle}}

[[Galvatron (G1)/IDW Generation 1 continuity|Galvatron]] also possessed a fusion cannon while on [[Earth]]. He regarded it as superior to [[Sunstreaker (G1)/IDW Generation 1 continuity|Sunstreaker's]] pistol when the Autobot tried to arrest him. {{storylink|All Hail Optimus Part 5: As Above...So Below|As Above...So Below}} [[Arcee (G1)/IDW Generation 1 continuity|Arcee]] subsequently overloaded the weapon during a confrontation in the atmosphere of [[Jupiter]], the resulting explosion managing to grievously damage Galvatron's right side. {{storylink|All Hail Optimus Part 6: No Fair Fights|No Fair Fights}}

===''Beast Wars'' cartoon continuity===
====''Beast Wars'' cartoon====
[[Megatron (G1)|Megatron]] loved his fusion cannon so much, he had another fusion cannon installed on the ''[[Nemesis (G1)|Nemesis]]''. The blast radius from this weapon is massive. Most kickass, though this one requires a power up time to fire again which is less kickass. {{storylink|Nemesis Part 2}} Although not Megatron's, according to ''Beast Wars'', the [[Ark (G1)|''Ark'']]'s cannon was also a generic fusion cannon. {{storylink|The Agenda (Part III)}}

====''Beast Machines''====
[[Megatron (BW)|Megatron]]'s personal chariot, [[Mechatron]], comes equipped with a fusion cannon to nullify any accursed [[Maximal]] that comes across.

===Live-action film series continuity===
[[File:Movie Megatron fusion cannon.jpg|thumb|left|upright=1.4| Back in the day when he needed both hands to hold/use it.]]
[[Megatron (Movie)|Megatron]]'s fusion cannon is one of the most powerful weapons known to Transformers. Drawing energy from an unknown interdimensional source, the fusion cannon fires gamma-irradiated plasma at a target.<ref>[http://www.hasbro.com/transformers/en_US/discover/Battle-Bios.cfm Battle Bios at Hasbro.com]</ref> It is also mentioned on [[Ironhide (Movie)|Ironhide]]'s toy packaging that he also carries a fusion cannon; presumably it is the blue glowing laser weapon on his left arm, though it is obviously much smaller than Megatron's.

[[File:ROTF Megatron fusion cannon.JPG|thumb|upright=1.4|Hey, I can see Starscream's house from here. *fires*]]
Megatron's cannon is presumably telescopic, as he keeps a pair of smaller, pistol-like cannons in each arm when not in use that combine to form one larger cannon. Its powerful blast is enough to send another transformer flying back three city blocks. Megatron used it on several occasions, most notably to injure [[Jazz (Movie)|Jazz]] and to knock [[Optimus Prime (Movie)|Optimus Prime]] into a building. {{storylink|Transformers (film)|Transformers}} 

[[File:DOTM-MegatronLincoln.jpg|upright=1.4|left|thumb]]
After his resurrection, Megatron still possessed his fusion cannon, but in a more compact form from which he could now access with his [[Death-lock pincer]], a lobster-like blade. A point blank shot can still send another transformer flying back several yards. During his battle with Optimus Prime in a forest, Megatron used the fusion cannon to knock the Autobot leader backward after shattering his [[mouthplate]]. Later, after impaling Optimus with the bladed pincer, Megatron finished the job by firing the fusion cannon right through Optimus. During the final battle in [[Egypt]], Megatron used the fusion cannon to shoot down a military helicopter. Following his resurrection, Optimus turned the fusion cannon against Megatron by blowing off ''half of his face'' and then severing it and Megatron's arm off with his [[Dual Energon Swords|Energon sword]]. {{storylink|Transformers: Revenge of the Fallen (film)|Revenge of the Fallen}} 

[[File:TLK Megatron fires.jpg|thumb|upright=1.4|I have my arm-mounted cannon. Y'all happy now?]]
Megatron later adopted a hand held fusion cannon that resembled a fusion shotgun. He used it to cripple [[Sentinel Prime (ROTF)|Sentinel Prime]] before he was decapitated and Optimus used the weapon to slay the ancient Prime. The deed done, Optimus threw it down in disgust. {{storylink|Transformers: Dark of the Moon (film)|Dark of the Moon}} Despite this, Optimus later reclaimed it as a replacement for his lost [[Ion blaster|ion blaster]]. When Optimus changed his paint schemes while going into and coming out of hiding, the cannon changed colour with him. Considering he never used it after being captured by [[Lockdown (ROTF)|Lockdown]], it is likely that the bounty hunter claimed the weapon. {{storylink|Transformers: Age of Extinction (film)|Age of Extinction}}

When Galvatron resumed his identity as Megatron, his new body possessed a new fusion cannon mounted on his right forearm. In addition to powerful energy bolts, the cannon could also act as flamethrower. It was separated from Megatron when Optimus Prime severed his right arm...again. {{storylink|Transformers: The Last Knight (film)|The Last Knight}}
{{-}}

===''Animated'' cartoon===
[[File:Mission Accomplished Starscream death 3.jpg|left|thumb|Given time, Starscream may simply develop an immunity to the cannon. Then again, maybe not.]]
[[Megatron (Animated)|Megatron]]'s iconic cannon served admirably as a cutting torch when Megatron sought to gain access to the [[Omega Supreme (Animated)|Autobots' ship]].<ref>Use of sound-effects from the original cartoon only served to enhance the weapon's coolness.</ref> {{storylink|Transform and Roll Out}} After Megatron's revival, his newly rebuilt fusion cannon proved even more effective against the Autobot ship by knocking it clean out of the sky in under a minute with some help from [[Lugnut (Animated)|Lugnut]] and [[Blitzwing (Animated)|Blitzwing]]. It also has an optical targeting lens... [[Stock footage|sometimes]]. {{storylink|Megatron Rising - Part 2}} It was instrumental in repeatedly killing the newly-immortal [[Starscream (Animated)|Starscream]], {{storylink|Mission Accomplished}} and was effectively used in the capture of Bulkhead. {{storylink|A Bridge Too Close, Part I}}

Eventually, it and his other miscellaneous weapons were removed when he was captured by [[Omega Supreme (Animated)|Omega Supreme's]] internal defenses. Optimus Prime discovered painfully that Megatron was not as weak without it as he had hoped. {{storylink|TransWarped}} Megatron later restored it to its rightful place on his arm, and used it as his primary weapon when he fought Optimus in the air. It survived the explosion of a [[Lugnut Supreme]], despite being damaged. Megatron shot Optimus Prime with it again, but this time it was ineffective, and [[Optimus Prime (Animated)|Optimus Prime]] destroyed it with [[Ultra Magnus (Animated)|Ultra Magnus's]] [[Magnus Hammer]]. {{storylink|Endgame, Part II}}

Notably Megatron, despite always precisely hitting Starscream, rarely manages to aim correctly when facing the Autobots. The writers were likely reluctant to [[The Transformers: The Movie|have half the cast atomized in the space of five seconds]], but to be fair, Starscream was unsurprisingly at point blank range for nearly every shot.
{{-}}

===''TransTech''===
High Commander [[Megatron (TransTech)|Megatron]]'s main weapon was his Tetra-Singularity Fusion cannon, a weapon that harnessed a small black hole as its power source and had no equal in [[Axiom Nexus]]. {{storylink|Rook - Axiom Nexus News: Investigative Journalist|Rook - Axiom Nexus News, 2015/05/13}} It has only been fired at full power [[Liege Maximo|once]]. {{storylink|Hasbro Transformers Collectors' Club issue 24|''TransTech'' Megatron's profile}}

===''Shattered Glass''===
[[Rumbler (SG)|Rumbler]] was the heroic [[Megatron (SG)|Megatron]]'s loyal sidearm. He was a [[Roller (G1)|semi-sentient drone]] in the shape of a fusion cannon. {{storylink|Do Over}}

[[Optimus Prime (SG)|Optimus Prime]] later gained a Quantum Fusion cannon upon his transformation into Nova Prime. {{storylink|Optimus Prime (SG)#NovaPrime|''Timelines'' Nova Prime profile card}}

===Aligned continuity family===
The Fusion Cannon could tap into interdimensional power sources to blast through almost any armor. [[Megatron (WFC)|Megatron]] had one, {{storylink|Bio|Megatron's Battle Bio}} and so did [[The Fallen]] when he was Megatronus.<ref>[http://www.allspark.com/content/view/7430/20/ AllSpark.com description of BotCon 2010 Hasbro designers' panel]</ref>

====''Prime'' cartoon====
Megatron's fortress of [[Darkmount (Earth)|Darkmount]] was armed with several fusion cannons. When a human army military force arrived at the fortress to wage a counterattack on the Decepticons, Megatron had one of the cannons fired at them, annihilating the humans and destroying the nearby abandoned city of [[Jasper]] in the process. Megatron warned [[William Fowler|Fowler]] that further human interference would result in the fusion cannons being turned on several major cities, including Washington, D.C. {{storylink|Darkmount, NV}} When [[Ultra Magnus (WFC)|Ultra Magnus]] arrived on Earth and reunited the majority of [[Team Prime]], {{storylink|Prey (episode)|Prey}} he and Fowler resolved to disable the fusion cannons before destroying Darkmount with the help of Earth's military. While [[Bulkhead (Prime)|Bulkhead]] and [[Wheeljack (Prime)|Wheeljack]] created a distraction at the base of the fortress, [[Arcee (WFC)|Arcee]] and [[Bumblebee (WFC)|Bumblebee]] attempted to sneak into the fortress to disable the cannons, but when met with heavy resistance, Magnus took matters into his own hands and mounted a one-bot assault on the cannons. He was stopped by Megatron, and though the Autobots were all captured, [[Optimus Prime (WFC)|Optimus Prime]]'s arrival quickly resulted in the fusion cannons being crippled, and then destroyed by Fowler's [[Skystriker (vehicle)|Skystriker]]s. {{storylink|Rebellion (Prime)|Rebellion}}

Megatron himself also had a fusion cannon<ref>Though unnamed in the series, it was named as such in the toyline.</ref> on his right arm, which seemed to be a standard arm-mounted energon cannon simply enhanced by [[Dark Energon]], but he promptly abandoned it when he got [[Liege Maximo|a dead Prime]]'s arm to replace his own in order to activate the [[Forge of Solus Prime]] to create the arguably more ''effective'' [[Dark Star Saber]]. {{storylink|Alpha/Omega}} Later, however, he lost that arm {{storylink|Darkest Hour (episode)|Darkest Hour}} and got his original arm back along with his fusion cannon. {{storylink|Darkmount, NV}} He was still able to use the Dark Star Saber with his fusion cannon arm in a final battle with the Autobots. {{storylink|Deadlock}} After being killed, he lost it again upon being resurrected by [[Unicron]], though he was able to access ''two'' [[Dark Energon]] cannons that were also extremely effective. {{storylink|Predacons Rising (Prime)|Predacons Rising}}

====''War for Cybertron''====
Megatron's precious cannon fired explosive charges into the faces of his enemies. Oddly enough, [[Optimus Prime (WFC)|Optimus Prime]] could also use one.

====''Transformers Devastation''====
The Fusion Cannon is a Grenade Launcher class weapon that can be unlocked by beating the game on any difficulty. When aiming, it will create a shield that blocks damage from the front. It can be equipped by [[Optimus Prime (G1)|Optimus Prime]], [[Grimlock (G1)|Grimlock]], and [[Wheeljack (G1)|Wheeljack]].

Megatron, of course, uses the Fusion Cannon as his primary weapon. He's also able to use the Fusion Cannon to create a forceful but harmless energy waves to fling his enemies away from him.

Another variant, "Fusion Cannon (Mod)", instead works like a shotgun; as one can guess, this variant is based on movieverse Megatron's fusion shotgun, down to it's appearance. This weapon lacks the aforementioned shield function.

==Notes==
[[File:MegatronAntimatterUK.jpg|thumb|upright=1.1|...or you could do that instead, sure.]]
* Generation 1 Megatron's on-[[Packaging|package]] [[bio]] refers his weapon as "'''particle beam cannon'''".<ref name=G1pack>Generation 1 Megatron's original on-package bio [http://www.botchthecrab.com/archive/techspecs/decepticon/1984/ts_megatron.jpg (scan at BotchTheCrab.com)]</ref>
* His Generation 1 on-package bio also mentioned he can "link up interdimensionally to a [[black hole]] and use [[Antimatter|anti-matter]] from it for use as a weapon," without elaborating further.<ref name=G1pack/> This, however, is a truncated version of the full bio provided to ''[[Transformers brand|Transformers]]'' writers and later published in ''[[The Transformers Universe]]'', which explains that his ''cannon'' draws on the antimatter as a power source.<ref>Generation 1 Megatron's extended bio [http://www.ntfa.net/universe/english/printerfriendly.php?char=Megatron (transcription at NTFA.net)]</ref> Apparently working from the shortened version, [[Simon Furman]] wrote [[Raiders of the Last Ark|two]] [[Resurrection!|stories]] in the [[The Transformers (Marvel comic)#Marvel UK|Marvel UK comics]] where Megatron channeled the antimatter through his body, unleashing it through his hands the first time and through his eyes the second time. It manifested as a black, starry cloud that caused explosions. A similar situation occurred in the cartoon. Megatron was never shown to possess antimatter-channeling abilities, but he was shown to possess an anti-matter blaster in "[[Enter the Nightbird]]". Like every Decepticon weapon in the cartoon, it produced a purple laserbeam, though one that "absorbed" energy. The fusion cannon-power-source interpretation has never featured in a story.
* The deep percussive note at the beginning of the iconic fusion cannon sound effect (used throughout Generation 1 and ''Animated'') is an old "stock" sound used frequently in American animation, most notably within [[wikipedia:Hanna-Barbera|Hanna-Barbera]]'s ''[[wikipedia:Scooby Doo|Scooby Doo]]'' where it was used to signify cast members or objects falling on the ground, running into walls, etc.
* According to the [[Transformers (Mystery of Convoy)|''Transformers: Mystery of Convoy'' strategy guide]], Megatron's fusion cannon functions as a flame thrower. No wonder he got defeated easily.
** Megatron's cannon in ''The Last Knight'' functioned as a flamethrower in one scene, possibly alluding to this...or following the "rule of cool".
