Slasher

Slasher is a Battle Chip that appears in many of the MegaMan Battle Network series games. It is used by pressing down on the A button. Whenever an enemy goes over to MegaMan's area, they automatically receive damage, until the player is hit with an attack, or releases the A button. The amount of damage varies depending on the game. It is not dropped by any viruses and is rare but can be bought in some games.
