Mekanorimon

Mekanorimon is a fictional character from the Digimon franchise, a Champion Level Machine Digimon. They are known to be little more than a sort of tank, always piloted by something. This has been confirmed by the fact that Gennai threw a Bakemon out of the one he hijacked. They might not always be piloted in the games/manga.
