Mega Buster, known as the Rock Buster (ロックバスター Rokku Basutā) in Japan, is a powerful arm cannon that is utilized by those named Mega Man in the eponymous franchise. While varying in function, the Mega Buster is most well known for shooting yellow shots of energy and possessing the ability to be charged to fire a Charge Shot. In the original timeline the Mega Buster was first invented by Dr. Thomas Light with several models being made by him. In the Mega Man Battle Network timeline, the origins of MegaMan.EXE's buster are not detailed, while the Star Force Mega Man's Mega Buster is the head of the EM Being Omega-Xis.

The original Mega Buster, originally called simply "P" (possibly standing for "player" or "power" as in the menu it displays the player's life energy instead of weapon energy) in early games, also known as Arm Cannon outside Japan, is Mega Man's primary weapon in the Mega Man games.
This Mega Buster is an ambidextrous arm cannon built by Dr. Light. It fires "Solar Bullets" (ソーラーブリット), energy bullets made of highly compressed solar energy, the same energy source used by Mega Man. It is a powerful weapon capable of puncturing steel and destroying boulders. A single, uncharged Solar Bullet can blow a five foot diameter hole in a wall of solid stone. With a few exceptions, like the non-canon remake Mega Man Powered Up, its bullets can pass through most walls.
In Mega Man 4 onward, the Mega Buster was upgraded to be able to charge energy up to two degrees, firing a Charge Shot. The Game Boy games allow for charging starting from Mega Man III. In Mega Man 9 and Mega Man 10, Mega Man lost the ability to charge his shots, suggesting that it has reverted to the original version. However, Mega Man can charge his shots again in Mega Man 11, and he gained the ability to increase its power and speed with the Double Gear System.
New Mega Buster
The New Mega Buster (ニューロックバスター Nyū Rokku Basutā, New Rock Buster) is an upgrade made in Mega Man 4. Mega Man can now charge solar energy to increase the power of his shots, attacking with a Charge Shot. The buster can be charged to two different levels: The first charge shot is bigger than normal shots, but causes the same amount of damage, although it can rip through enemies that it defeats (compared to standard shots, which dissipate even if they destroy an enemy). A fully charged shot is bigger than the first, and deals three times more damage than normal shots. Except for the color, the charge shot from Proto Man's Proto Buster uses the same graphics from this buster's charge shot in Mega Man 9 and 10.
Super Mega Buster
Super Mega Buster (スーパーロックバスター , Super Rock Buster) is a modification made by Dr. Cossack in Mega Man 5. The charge shot gets more power having a larger projectile and shorter charge time, but if Mega Man suffers damage while charging a shot, the charged energy will be lost and he will need to charge again.
In Mega Man IV, Mega Man doesn't lose charged energy when hit, but a fully charged shot causes recoil, throwing Mega Man backwards a small distance from his current position. If the player gets a Game Over several times in the same stage without leaving it, Dr. Light will give an enhancement that will make it charge energy faster. The recoil is also present in the opening scene of Mega Man V, where the charge shot couldn't harm Terra.
The Mega Arm, known as Rock'n Arm (ロックンアーム) in Japan, is an upgrade of the Super Mega Buster done by Dr. Light in the game Mega Man V to help Mega Man in his battle against the Stardroids. Unlike the Super Mega Buster, it doesn't have recoil from charge shots, and the charged energy isn't lost when hit. It can charge energy to fire Mega Man's fist like Hard Man's Hard Knuckle and the Rocket Buster. Mega Man is incapable of using his regular Mega Buster while his arm is detached from his body, and therefore is incapable of fighting back until it is reattached.
There are three enhancements for the Mega Arm:
- MH (マジックハンド, Magic Hand) - Can grab items from far away with Mega Man's hand. Costs 90 P Chips.
- CL (ロックンクロー, Rock'n Claw) - Can grab and attack the enemy over and over. Costs 100 P Chips.
- Turbo Accelerator (パワーアップパーツ, Power Up Parts in Japan) - The Mega Arm fires and charges much faster. Obtained by getting a game over four times in a row in the same stage. Can be upgraded up to two times. It's not saved by passwords, but it can be obtained again at any time.
Hyper Mega Buster
Hyper Mega Buster (ハイパーロックバスター , Hyper Rock Buster) is a modification from Mega Man 6. Like the Super Mega Buster, Mega Man loses the charged energy if hit by an enemy, needing to recharge to fire a charge shot.
From Mega Man 7 onward, Mega Man's main weapon is only referred to as the "Mega Buster" and functions like the New Mega Buster in most appearances, using similar charge effects and projectile behavior and does not lose charge upon damage.
Double Mega Buster
The Double Mega Buster is the Mega Buster used on both arms. The Double Mega Buster was only used by Mega Man at the end of Super Adventure Rockman in order to defeat Ra Moon, charging a large amount of energy in both busters, which he then fires simultaneously to generate an incredibly powerful charge shot. However, it is too dangerous for Mega Man to use regularly, as it drains his energy much faster than he can normally replenish it, also causing him to overheat.
In Super Smash Bros. for Nintendo 3DS / Wii U and Super Smash Bros. Ultimate, Mega Man will transform both of his arms into busters when using Flame Blast and Spark Shock, with a similar effect of having to vent heat from them afterward.

Mega Man X
The X Buster (エックスバスター) is the Mega Buster Mark 17 used by Mega Man X, his primary weapon in all games from the Mega Man X series. Like the original Mega Buster, it can be used in any arm and fires highly compressed blasts of energy, which can be charged up for extra power.
MegaMan Volnutt's Mega Buster differs from most models in that it does not allow for charging; it instead allows for rapid fire, similar to the Bass Buster or Axl's pistols, only being able to charge in Tatsunoko vs. Capcom. MegaMan's buster is modified by Buster Parts. These modify four abilities: Attack, Energy, Rapid, and Range. Normally, MegaMan is only allowed to use two Buster Parts at a time, but upon obtaining the Adapter Plug, he can equip three parts.
Throughout the Mega Man Battle Network series, MegaMan.EXE's Mega Buster goes through many upgrades and modifications. In the first two games it starts weak, slow, and unable to charge, but after receiving enough Power UPs it becomes a powerful rapid fire weapon with the ability to fire charge shots. Charge shot is available from the beginning in later appearances.
Star Force Mega Man
The Mega Buster from the Star Force Mega Man is, instead of a traditional buster, Omega-Xis's head. This version charges automatically, with automatic rapid fire added. Its stats and abilities are changed with various weapons. In the third game, as an effect of wearing the Hunter-VG, Mega Man's left hand is now normal, with a design similar to Omega-Xis. The Mega Buster is now more traditional in design as well. This version of the Mega Buster allows Mega Man to lock on and teleport to the enemy to use close range cards.
The Mega Buster appears in Devil May Cry 5, available to Nero as a Devil Breaker for those who purchased the Deluxe Edition of the game or purchased the Deluxe Upgrade DLC. Modeled after Mega Man's Mega Buster, this essentially grants Nero a second firearm in the form of plasma shots and can be charged for a more powerful blast. Using the Mega Buster also changes Nero's jump to mirror that of Mega Man's as well as a Slide dodge maneuver and holds the Buster in the same fashion when running. As standard for all Devil Breakers, the Mega Buster has a Wire Snatch tool that immediately pulls enemies towards him or to them.
Mega Man's Plasma Cannon functioned somewhat differently from the Mega Buster in the animated series. It is a plasma weapon that fires plasma shots instead of solar powered shots. Mega Man could only use the blaster on his left arm, giving him an asymmetrical arm design. It was never show to have charging capabilities, but Mega Man was shown at least once to be able to manually adjust its power, and apparently on a subconscious level as well as, depending on how angry he was. He can make his shots very small, powerful enough to pierce a robot, or even ricochet. By touching a robot, Mega Man can steal that robot's power with his internal weapons converter instead of copying it, leaving the target defenseless.
Mega Man's Mega Buster functions similarly to others Mega Busters, being able to fire normal and charged shots. It has three rectangles that functions as a display to select copied schematics manually. Unlike other busters, this version uses a replication beam to download a Robot Master's schematics, allowing Mega Man to copy a weapon without defeating or making physical contact first at the cost of taking time to fully acquire the weapon.
Like in the games, Mega Man can utilize the Mega Buster. The Mega Buster was also the primary reason why Rock was named "Mega Man" instead of "Rock Man" or "Copy Man." However, he cannot use it when utilizing a Special Weapon, due to his Variable Weapons system only allowing himself to use one weapons system at a time. In addition, its power source was a chip. Removing the chip would disable the Mega Buster, as Sonic the Hedgehog proved during their fight in the Worlds Collide arc. Sonic, when continuing their fight in Mega Man's realm, sarcastically referred to the Mega Buster as a "lemon shooter" when arrogantly telling Mega Man that he can't fire his weapon and that he'll destroy Eddie, Rush, Tango, and Beat easily.
Prior to the fight with Sonic, Mega Man encountered the Roboticized Masters and learned that a charge shot from the Mega Buster was able to stun them in combat. After teaming up with Sonic, the charged shot combined with Sonic's Spin Dash caused a cascade failure in the robotization process with Tails Man, returning him to normal when his weapon data was downloaded. Later on, Tails performs an upgrade on the Mega Buster in mid-battle against Charmy Man, Espio Man, and Vector Man while Sonic distracts them, giving Mega Man's charge shot the same properties as Sonic's Spin Dash, creating the Spin Dash Blast / Sonic Shot which can deroboticize a target with a single clean shot, though Mega Man still needed to make use of Special Weapon weaknesses in order to get a clean shot in some cases. Later, Mega Man and Sonic, in super forms, used a giant charge shot with Super Sonic as projectile to destroy the Egg-Wily Machine X. Mega Man then charges Chaos energy in the Mega Buster to use Chaos Control, reverting the effects of the Genesis Wave in his world.
Mega Man later used the Double Mega Buster as a last ditch effort to stop Ra Moon, an act that came very close to destroying him.
The Mega Buster is an unique weapon able to scan and replicate the weapons of other robots, the Weapon Change System being one of Dr. Light's greatest accomplishments. Even a century later, in 21XX, scientists still would not be able to replicate anything close to the Mega Buster for common use. It was later upgraded to be able to fire charge shots, and as Mega Man gained experience, he became more efficient in battle without having to rely on special weapons.
The Copy Mega Man is capable of exploring the limits of his own potential regardless of personal danger, whereas the real Mega Man's power levels are set to the maximum level that is possible without running the risk of overloading him.
