About: Niko is an underground artist who likes dark and primal settings and enjoys indulging in rap battles where he can express all his latent aggression. He produces himself on stage to realize his fantasies and express his rough attitude; he's not in it for the money, which he finds impure and contradictory to his lifestyle. Very dominating, he likes having his cohort of docile (and consenting) males, that he uses and abuses for his personal pleasure. His dominant male soul expresses itself magically under the guise of a tentacular aura. Rejected by the Ninja Village where he grew up for unknown reasons, he never forgot his values of justice and order. It's for that reason he became a vigilante.
Niko is actually an alt of the original parody guy. Reason for the police outfit and "Cop" in the name. But he does have a similar hair style to Killer B, and is always wearing sunglasses. They also both seem to share a cocky attitude (at least this conclusion can be drawn through his facial expression and Bio). A big difference between them is Niko being rejected from the ninja village, while Killer B was beloved in Kumo and called "Hero of Heroes". Niko also shares similar beast tentacle abilities, but none of his poses display this, it's just stated in the bio.
