Mega Buster (Omega-Xis)

The Mega Buster, known as Rock Buster (ロックバスター) in Japan, is the Mega Buster of the Mega Man from the Mega Man Star Force series. It is Omega-Xis's head. This version has automatic rapid fire, and when not in use, it will automatically charge to fire a stronger shot. This version of the Mega Buster allows Mega Man to lock-on and teleport to the enemy to use close range Battle Cards, known as "predation".

In Mega Man Star Force 3, 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.

Mega Weapons / Wizard Equips
The Mega Weapons, known as Wizard Equips in the third game, are special types of weapons (similar to the Power Up Items in Mega Man Battle Network), which allow Omega-Xis to change his Attack strength, his Rapid fire rate, or how fast the MegaBuster can Charge. Certain weapons can even modify the properties of the Charge Shot or alter the results of the battle.

Trivia

 * In the second and third game there is an Ability Wave, Humor Buster (HumrBstr), that changes the sound of the Mega Buster's shots to dog barks. The third game also has a Humor Buster 2 (HumrBst2) Ability that changes the sound to meows.
 * Though they cause no overt modification to Mega Man's appearance, a handful of the weapons imply that they should by virtue of being named for jewelry (rings, bracelets, and piercings).
