Puff Ball

PuffBall is a virus from the Mega Man Battle Network series, resembling a puffy tree. The virus's mask protects them from all frontal attacks. While attacking, it will stick out its mask and release poison clouds onto panels surrounding the mask. It can only be damage while attacking, with its mask sticking out (the mask still acts as a one panel shield). PuffBall can also use AreaGrab to move forward even more. Stronger variants can use AreaGrab more times.
