Mega Buster

Mega Buster (ロックバスター) is a powerful arm cannon that is the main weapon from all the characters named Mega Man (Mega Man, Mega Man X, Mega Man Volnutt/Trigger and MegaMan.EXE). It was created by Dr. Light with the first Mega Man.

Mega Buster / Arm Cannon
The first Mega Buster, originally known simply as Plasma and Arm Cannon in the first three Mega Man games. It can fire three bullets at a time that, with the exception of the remake Mega Man Powered Up, can pass through walls.

New Mega Buster
The New Mega Buster (ニューロックバスター) is an upgrade made in Mega Man 4. It can be charged to cause more damage.

Super Mega Buster
Super Mega Buster (スーパーロックバスター) is a modification made by Dr. Cossack in Mega Man 5. The charged shot gets more power, but it throws Mega Man backwards in Mega Man IV and V.

Mega Arm
The Mega Arm (ロックンアーム) is an upgrade of the Super Mega Buster that only appeared in Mega Man V for Game Boy. It can charge energy to fire Mega Man's fist like Hard Man's Hard Knuckle.

There are two items that enhances the Mega Arm:
 * MH: Can grab items from far away with Mega Man's hand. Costs 90 P-Chips.
 * CL: Can grab and attack the enemy over and over. Costs 100 P Chips.

Hyper Mega Buster
Hyper Mega Buster (ハイパーロックバスター) is a modification from Mega Man 6. Mega Man no longer goes backward after a Charge Shot, but he loses the charged energy if hit by an enemy.

X-Buster
The powerful X-Buster is the Mega Buster Mark 17(MK 17) used by Mega Man X. It is implied that the Buster's technology is passed on to Zero's Z-saber in the Zero series, allowing him to charge it. The X-Buster also makes a cameo in Mega Man Legends as a toy.

Mega Buster
Megaman Trigger's buster differs from most models in that it does not allow for charging, and instead, Rapidfire. Megaman's buster is modified by busterparts, which he finds or buys. These modify 4 stats, Attack, Energy (how many fires can be shot before stopping for a moment), Rapid, and Range. Stats can range anywhere between 1, or 8. Normally, Megaman is only allowed 2 busterparts at at a time, but upon obtaining the Adapter plug, he can equip 3. In both games, when playing Easy mode, the player starts the game with the Accessory Pack Omega, which maximizes all 4 buster stats.

Throughout the MegaMan Battle Network series MegaMan.EXE's Mega Buster goes through many upgrades and modifications.

Mega Buster
The Mega buster in this carnation is, instead of a traditional buster, Omega-xis' head. This version charges automatically, with automatic rapidfire added. It's stats and abilities are changed by equipping various Mega Weapons (Known in the third game as Wizard Equips). In the third game, as an effect of wearing the VG Hunter, MegaMan's left hand is now normal, with a design similar to Omega-Xis. The Megabuster is now more traditional in design aswell.
