Pole

Pole (ポール) is a tadpole robot in Mega Man 3 that appears in Gemini Man's stage, both regular and when in pursuit of Doc Robot. It was originally created for energy resource research. They stay in eggs that block Mega Man's way. If shot with the Mega Buster or Needle Cannon, the egg breaks to release the Pole, which slowly chases Mega Man until he shoots it.

They appear in Gemini Man's Stage again in Mega Man III and the 3rd Wily Tower Stage in Mega Man: The Wily Wars.

Other Media
Poles make an brief appearance in Gemini Man's base in issue 42 of the Archie Comics Mega Man series and in the Rockman World 3 manga, while Mega Man blasts through them and their egg nests.
