Scworm

Scworm (スクワーム) is an enemy in Mega Man 2. It appears in Flash Man's stage, Air Man's stage, Quick Man's stage, and in the first section of Dr. Wily's castle. They tend to shoot up distorted iron pipes that hop out. Mega Man would need a low hitting weapon to destroy the source. The pipes themselves self-destruct eventually, or they can be shot.

Scworm in the Battle Network series
Scworms appear as viruses in Mega Man Network Transmission. They act the same as the original. They are in an obscure section of the Bank Comp, so it is possible for players to continue through the game without seeing one.

Metrenger
Metrenger (メートルンガー) is an enemy similar to the Scworm, but they release large worm robots instead. They are located on the ceilings from the stages of Clown Man, Grenade Man, and the Wily Stage 2 in Mega Man 8, and in Ground Man's stage in Mega Man & Bass. In Mega Man 8, Metrengers are orange-and-purple; in Mega Man & Bass, they are orange-and-green. The source of these creatures cannot be destroyed.
