Shubafun

Shubafun (シューバフン) is an indestructible Reaverbot from Mega Man Legends 2 that acts like a trap, hiding in the ground waiting to bite passing Diggers to drain their energy. If Mega Man Volnutt steps on one, he can avoid being bitten by rolling before its mouth closes. If caught, the only way to escape from its jaws is by violently struggling. It appears in Saul Kada Ruins and Elysium.
