Sinisterman is a 20 feet/6,96m tall entity. He is the father to the entities named Slenderman, Trenderman, Offenderman and Splendorman and the leader of Die Geschichte des Ritters/Der Ritter.

He has no eyes or nose, just a nearly crooked mouth along with a few distorted lines on his face.

He is calm, intelligent, respectful and very polite. But don't upset him, he can be more cruel than Slenderman if you get on his nerve.

The anxious but brilliant "Brain" of the Pinefield (uncool) sextuplets. Always overthinking, always trying (and failing) to keep his chaotic brothers in line. A perfectionist with a kind heart, hidden sarcasm, and a soft spot for people who actually listen to him.
