A dirty fighter that even Devimon hates to fight. Though it is a subspecies of Devimon, it completely lacks all emotions but hatred due to its lonely life in the ocean depths. In order to win by any means, it won't let up with its attacks even if the opponent loses their fighting spirit. The two tentacles growing from its back each possess their own will, so they will struggle for the catch and act without permission. Its Special Move is discharging a venomous ink from its mouth (Guilty Black).

An aquatic dirty fighter that it is said even Devimon hates to fight, due to its brutal reputation. Though, as its name suggests, it is a subspecies of Devimon, it completely lacks all emotions but hatred due to its lonely life in the profound ocean depths. For that reason, to ensure that it gains victory by any means, it won't let up with its attacks even if the opponent loses their fighting spirit midway through. The two big tentacles growing from its back appear large and special, but they each possess their own will, so they will struggle for the catch and act without permission. Its Special Move is spraying a venomous ink from its mouth (Guilty Black), and if this attack hits the opponent is unable to stand for a while.
