The man is a doctor who was once called darkness
Unable to atone for the past,
Covering the present along with the endless undying darkness...
Weiss is a tall man with dark orange eyes and long gray hair, tied back into a ponytail with bangs in the front. His attire consists of a black turtleneck jumpsuit with gray sections on the legs, gray fingerless gloves, black shoes, and two crossed bands in the front. Over his outfit he wears a white doctor coat, as well as a white headband and headset.
Weiss' 2P palette gives him deep blue hair and green eyes. The colors of his jumpsuit are inverted, with the suit being light gray with black sections on the legs and black bands on his chest. His coat is olive green, and both his headband and headset are black.
Weiss makes a cameo in Black's Lose animation in Lapistoria, wearing his normal attire.
