Dark Roper

A mysterious black and purple-bodied monster with multiple tentacles. It uses its tentacles as legs to move around. Its existence shrouded in mystery, it lives on the miasma full continent of Gronoa, and all that is known about it is that its poisonous-looking body is likely thanks to its surroundings. Since nothing resembling eyes can be seen on it, it is thought that it might use its tentacles to sense its surroundings.
