Rumbling Bang (ランブリングバン Ranburingu Ban?) is a Leg-type napalm weapon that Vile obtains by defeating Spark Mandrill in Mega Man Maverick Hunter X. When equipped, Viles shoots a grenade that behaves in a similar fashion to Bumpity Boom, except when it explodes, it creates a wide swath of green fire. Rumbling Bang appears to do little damage, but it covers a fairly wide range horizontally. Defeating Spark Mandrill will Vile not only be rewarded with Rumbling Bang, but he will also be rewarded with Go-Getter Right as well.
