CFN-24 is an orb-like aquatic enemy in Mega Man 7 that only appears in Burst Man's stage. If shot at or touched, it will explode, and the explosion does some damage to Mega Man, acting like an underwater mine. There are two types of CFN-24: a blue one that bobs up and down underwater, and orange ones, which always float at the waters surface (ironically enough, it only appears on the second purple chemical stage, and also, to make it harder the chemicals are floating up and down).
