BomBoy (ボムボーイ BomBoy?) is a virus from the Mega Man Battle Network series. It starts off in the back row of its field and creates a bomb that it gradually pushes towards its target's field. If the bomb makes contact with the target's field, it will explode. The bomb can be pushed back and destroyed, but once the bomb has been destroyed, the virus will go back to the back row and start the process over. The bomb will deflect most attacks from hitting the virus, so the only way to damage the virus is to use attacks that bypass the bomb's deflections.
