Shekuten

Shekuten (シェクテン) is a small Reaverbot from Mega Man Legends that appears in the Underground Ruins. They are not very tough on their own, so they generally come in groups. Shekutens usually stay still on the ground, appearing to be inactive and being invincible while in this state. When approached, they will stand up and follow Mega Man Volnutt for a short distance before returning to their stationary behavior. If a Shekuten manages to get close, it will start flashing red and self-destruct shortly after. When any Shekuten starts flashing, all Shekutens in the room will stand up and follow the intruder for a while, regardless of their distance.

Trivia

 * These enemies have some resemblance to the Mets, in that they are small and are invincible while under their shell.
