Mandomantal

The Mandomantaru (マンドマンタル) appears to be a one of a kind Reaverbot. This is one of the few peaceful Reaverbots that will not attack. It can be found in the deepest part of the Nino Ruins. The Mandomantaru can still hurt Mega Man Volnutt if he is in its path. It is often referred to as the Trilobyte or Manta Reaverbot.

Its use in the game is to ride on it, mentioned by its flat body. Riding on it allows one to get to the chests on the high pillars in the area, normally unreachable even underwater. It, unfortunately, either disappears or is destroyed once the water is drained, as it apparently cannot survive out of water, much like a real fish. It can also be killed, and once it is close to dying, it will attack Mega Man with balls of electricity as a last ditch effort to save itself.
