Fusion cannon

A release of lubricant is quite common when seeing this.

The fusion cannon is Megatron's signature weapon. It is attached to his right arm and devastatingly powerful as demonstrated by its sudden removal of Ironhide's head. (It is at least as powerful as Fortress Maximus's hands in comparison.) It strikes fear into the sparks of both the Autobots and Decepticons though this description and its actual destructive capacity seems strangely uneven.

Hey-o!

While on a hunt for Optimus Prime the Predacons betrayed Megatron. Divebomb stole Megatron's fusion cannon and the Predacons left Megatron to fight Optimus Prime with only his small backup gun. Megatron opened a space bridge which pulled both him and Prime to Cybertron where Megatron got a new fusion cannon. ...The Harder They Die! It is unknown what Divebomb did with the original.

Fusion cannon Megatron's fusion cannon from the Generation 1 cartoon. — 14 KB

During a battle with the Autobots and Decepticons Megatron's fusion cannon was fired twice destroying an oil rig and trapping various Autobots and humans. It was then fired once more to ignite oil and create an enormous conflagration 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 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 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. 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 mine in Burma. After the debacle at the mine Starscream got rebellious and tried to shoot Megatron. But he deflected the blast with a force field projected from the fusion cannon and 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 base to make the double-bluff more convincing. It reappeared at the final battle outside the Decepticon 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—so Megatron picked up the fusion cannon once more and used it to punish Starscream again before the cruiser crashed. More than Meets the Eye, Part 3

So after that defeat the Decepticons didn't show up for months and when they did Megatron used his 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... uhhhh... gut with the cannon. The Decepticons then took the Energon they stole from the plant to the space bridge. 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. Transport to Oblivion

When the Decepticons invaded a science lab to steal an antimatter formula the Autobots tried to stop them and Megatron fired at the Autobots and their holograms 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. 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 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 useless for the rest of the battle. Divide and Conquer

At the North Pole or thereabouts during another battle with Prime where the cannon was used to shoot Optimus in the back, it was once again knocked off. This time it was knocked off by a crystal shard thrown by Prime. 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's earthquake powers collapsing it and dumping the Autobots into the nearby river. S.O.S. Dinobots

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 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 blast's kickback knocked Brawn over again. Finally Laserbeak retrieved the gun for Megatron and another shot was fired at Brawn but no one had to fall down because the shot missed.

Back at the pyramid Megatron used the cannon to cause a distraction for the Autobots by blasting a mountainside twice and causing an avalanche. Fire on the Mountain

Then there was the time Megatron tried to bring 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, Ironhide, Prowl, 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 of Megatron's giant space bridge. The Ultimate Doom, Part 1

Megatron's environment-destroying plan saw the Decepticons getting trapped in their own base so he used the cannon to blast yet another hole in a wall to escape. 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 again though). The Ultimate Doom, Part 3 Despite the Energon ship exploding neither Megatron nor the cannon were destroyed and he employed his signature gun again in a battle outside Doctor Arkeville'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 a slight hyperbole.) Countdown to Extinction

Yeah, I know this actually is a scope but can you play dead at least? Are you a Headmaster or something?

During an incident with the 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 put it back on when 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. A Plague of Insecticons

As we know all Transformers or at least Decepticons get their special powers from power chip rectifiers, 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 cannon blasts to finish off Prime during the battle.Heavy Metal War

An attempted coup from Devastator is another matter. The shots continuously bounced off his armor and Megatron had to resort to a 5-way fistfight with Starscream, Astrotrain and Blitzwing as an alternative. 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 his fusion cannon was replaced by an arguably far more effective particle cannon which he promptly used to kill Starscream. The Transformers: The Movie

Fight! Super Robot Lifeform Transformers manga

Can we have a Green Lantern/Transformers crossover now?

The Megatron Corps (メガトロン軍団 Megatron Gundan) are a horde of six Megatron clones created by Galvatron to overwhelm the Autobots. Each clone is gifted with a unique Fusion Cannon and they are capable of combining their blasts into a single devastating attack, called the self-explanatory "Combined Fusion Cannon attack." No member of the Megatron Corps is gifted with sentient intelligence, however, as they are all controlled by the will of Galvatron who was, in reality, the original Megatron before his upgrade from Unicron. Galvatron would keep this hidden by also posing as a Megatron Corps clone... using a particle cannon instead of a Fusion Cannon.

As soon as Galvatron lost control over the Megatron Corps in a fight with Rodimus Prime the clones lost their power and were easily disposed of. The Story of Super Robot Lifeforms: The Transformers #2

Having defeated Megatron, 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.

Megatron demanded Tarn come face him in battle but a well-placed shot by Nickel and Vos destroyed the cannon leaving him defenseless. Rage, Rage Despite this Megatron kept the weapon attached to his arm even after the battle was over.

Beast Wars cartoon continuity

Beast Wars cartoon

Megatron loved his fusion cannon so much, he had another fusion cannon installed on the 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. Nemesis Part 2 Although not Megatron's, according to Beast Wars the Ark's was also a generic fusion cannon. The Agenda (Part III)

Megatron's personal chariot Mechatron comes equipped with a fusion cannon to nullify any accursed Maximals that come across it.

Live-action film series continuity

Back in the day when he needed both hands to hold/use it.

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. It is also mentioned on Ironhide's toy packaging that he also carries a fusion cannon; presumably it is the blue glowing laser weapon on his left arm though obviously much smaller than Megatron's.

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 a larger one. 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 and to knock Optimus Prime into a building. Transformers

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 or another considerable distance. During his battle with Optimus in a forest Megatron used the fusion cannon to knock the Autobot leader backwards after shattering his mouthplate. Later after impaling Optimus with the bladed pincer Megatron finished the job by firing the cannon right through Optimus's chest (including his spark chamber). During the final battle in Egypt Megatron used the cannon to shoot down a human military helicopter. Following his resurrection, Optimus turned the cannon against Megatron by blowing off half his face and then severing it and Megatron's arm off with his Energon sword. Revenge of the Fallen

I have my arm-mounted cannon. Y'all happy now?

Megatron later adopted a handheld fusion cannon that resembled a shotgun. He used it to cripple 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. Dark of the Moon Despite this Optimus later reclaimed it as a replacement for his lost ion blaster. When Optimus changed his paint schemes while going into and coming out of hiding the cannon changed colors with him. Considering he never used it after being captured by Lockdown it is likely that the bounty hunter claimed the weapon. 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 cannon arm...again. The Last Knight

Animated cartoon

Given time, Starscream may simply develop immunity to the cannon. Then again, maybe not.

Megatron's iconic cannon served admirably as a cutting torch when Megatron sought to gain access to the Autobots' ship. Unfortunately, it was seemingly obliterated when an overload device planted by none other than the traitorous Starscream activated causing an explosion that not only breached the enemy ship's hull automatically but also severed much of Megatron's cannon arm as well. Transform and Roll Out After Megatron's revival his rebuilt fusion cannon proved even more effective than before against the Autobot ship and in general by knocking it clean out of the sky in under a minute with help from Lugnut and Blitzwing. It also has an optical targeting lens... sometimes. Megatron Rising - Part 2 It was instrumental in repeatedly killing a newly-immortal Starscream Mission Accomplished and effectively used to capture Bulkhead. A Bridge Too Close, Part I

Eventually it and his other miscellaneous weapons were removed when he and Starscream's severed head was captured by Omega Supreme's internal defenses. Optimus Prime discovered painfully that Megatron was not as weak without it as he hoped the Decepticon leader would have been. 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 single Starscream-controlled Lugnut Supreme despite being damaged. Megatron shot Optimus Prime with it again but this time it was ineffective and Optimus destroyed it with the defeated Ultra Magnus's legendary hammer. Endgame, Part II

Notably, Megatron, despite always precisely hitting Starscream rarely manages to aim correctly when facing Autobots. The writers were likely reluctant to have half the cast or so atomized in the space of five seconds, but to be fair Starscream was unsurprisingly at point-blank range for nearly every shot directed at him.

High Commander 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. Rook - Axiom Nexus News, 2015/05/13 It has only been fired at full power once. TransTech Megatron's profile

Fusion cannons could tap into interdimensional power sources or other means to blast through almost any form of armor-plating. Megatron had one Megatron's Battle Bio and so did The Fallen both when and after he was still called Megatronus.

Prime cartoon

Megatron's second fortress named Darkmount was armed with larger-scale fusion cannons. When a human army military force arrived to counterattack Megatron had one of the cannons fired at them annihilating the humans and their vehicles, additionally destroying the abandoned city of Jasper in the process. Megatron warned Agent Fowler further human interference would result in the cannons being turned on more major cities including Washington, D.C. Darkmount, NV When Ultra Magnus arrived on Earth and reunited the majority of Team Prime Prey he and Fowler resolved to disable the fusion cannons before trying to destroy Darkmount with Earth's military again. While Bulkhead and Wheeljack created a distraction at the base of the fortress, Arcee and Bumblebee attempted to sneak into it to disable the cannons but when met with heavy resistance Magnus took matters into his own hands and mounted a one-bot assault on them. He was fairly easily stopped by Megatron and though the Autobots were captured Optimus Prime's arrival quickly resulted in the cannons being crippled and destroyed by Fowler's Skystrikers. Rebellion

Megatron himself also had a fusion cannon on his right arm which was much smaller in comparison and seemed to be a standard Energon cannon simply enhanced by Dark Energon, One Shall Fall but he promptly abandoned it when he got a dead Prime's arm to replace his own to activate the Forge of Solus Prime for creating the arguably more effective Dark Star Saber. Alpha/Omega Later, however he lost that arm to the regular version of his energy sword Darkest Hour and got his original arm back along with the cannon. Darkmount, NV He was still able to use the Dark Star Saber with his fusion cannon arm in a final battle with the Autobots. Deadlock After being killed by Bumblebee with the regular Star Saber he lost it again (permanently this time) upon being resurrected by Unicron though he could access two Dark Energon-powered cannons that were also extremely effective.

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, Grimlock and Wheeljack.

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

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

Toys

Megatrons with Fusion Cannons

So many Fusion Cannons, so few targets.

As the Fusion Cannon is Megatron's signature weapon, we at the wiki quickly realized that posting every instance of a Megatron with a Fusion Cannon would be perhaps a bit much. Not to mention, it would be shorter to list those who didn't have one. For brevity, and sanity, the following Megatrons (Megatronii?) are commonly known to carry Fusion Cannons into combat on their toys and merchandise:

• The Generation 1 incarnation, which covers the Megatron found in Marvel Comics, the original cartoon, and IDW's line of comics, among others.
• The live-action film incarnation, featured in four out of the five major movies.
• The Animated incarnation.
• The Aligned incarnation, featured in several video games, novels and Transformers Prime.
• Megatronus, while not a Megatron, always has a Fusion Cannon in the 2015 Robots in Disguise franchise.

Meanwhile, the following toys either feature one-shot (continuity wise) Megatrons with Fusion Cannons, or other characters with toys who have been issued Fusion Cannons:

Beast Machines

• Mechatron (Beast Rider, 2000)
  • Accessories: 2 missiles

Mechatron features a central fusion cannon.

• Mechatron (Beast Rider, 2001)
  • Accessories: 2 missiles

Later on, Mechatron was given a running change redeco into a shocking purple, yellow, and copper coloration, though the packaging was not changed in any way to reflect this.

Timelines

I don't feel like I fit in here.

• Nova Prime (Deluxe, 2015)

Notes

...or you could do that instead, sure.

• Generation 1 Megatron's on-package bio refers his weapon as a "particle beam cannon".
• His Generation 1 on-package bio also mentioned he can "link up interdimensionally to a black hole and use anti-matter from it for use as a weapon," without elaborating further. This, however, is a truncated version of the full bio provided to Transformers writers and later published in The Transformers Universe, which explains that his cannon draws on the antimatter as a power source. Apparently working from the shortened version, Simon Furman wrote two stories in the 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 Hanna-Barbera's 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 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".
