The Shekuten (シェクテン,Shekuten?) is a walking mine-like Reaverbot. These Reaverbots will activate and pop up from the ground when an intruder passes by them. They will follow the intruder for a short distance and explode if near the intruder.
These enemies have some resemblance to the Mets, in that they are small and are invincible while under their shell.
