Spidy

Spidy, known as "Kūmosu" (クーモス) in Japan, is a virus from Mega Man Battle Network 4. It pauses for a moment on its side of the field until it moves in a straight line towards its target. It then continues to chase the target in a straight line around the target's field until either the virus or the target is deleted. Higher level variants shoot out two webs on random panels that can trap the target if the target runs into them. The webs disappear after a duration of time.
