Wind Box

WindBox (ウインドボックス) is a virus from the Mega Man Battle Network series. The virus itself won't be able to damage its target. However, it can blow its target away from it, potentially hindering the movement pattern of its target. Variants can either pull in the target via vacuum or do both blow and pull. As the level increases on variants, the frequency and power at which it blows or pulls also increases. The virus remains stationary and does not move.

Battle Chips
The WindBox family has two Battle Chips. Wind (トップウ) summons a WindBox with 100-200 HP (depending of the game) in front of the user that will generate wind to push the opponents away. Fan (スイコミ) summons a VacuumFan that pulls opponents. None of them do damage, but when used on sand panels, it will blow or suck the sand away from the stage, causing some damage in the process.
