Professor, Igneous Pacoste. Genius Toxinologist whom works alongside Dr. Alf Jainyu, as his partner.
Igneous takes extreme measures to make sure he doesn't accidentally poison any one, not with the toxins which he studies, but with his own.
He is also kind of like an Uncle to Kisamata, the Rational Uncle, whom keeps her away from his lab.
He's also working to find a way to help Jainyu become his old self again... if possible.
