Catalyst is one of the messengers of the underworld, who relay information between demons and also between the underworld and the living world. He doesn’t wear the traditional attire for a messenger, instead opting for a spiked leather jacket and sunglasses. Catalyst is self-centered and egotistical, and tries (and fails) to act aloof to mask his insecurities, making others just see him as a jerk. He flusters easily and is easily provoked. He isn't the sharpest tool in the shed, and often gets into trouble. Deep down, however, he has a good heart (how deep down you have to look for it depends on the person).
