Nergal is an emotional black hole. He sucks up all the feelings from those around him and unleashes them in devilish displays of absolute mindless temper, termed a mega tantrum by his handler, but he is otherwise very closed off and aggressive with any other Tokota he comes across. Attempts to play are met with flashing fangs and during hunts he is prone to walking in his own direction and ignoring all others. His one delight is fishing alongside any Toko that can respect the fact he is the king of the water and his space is sacred.
