K’Vathrak, coined by Donatello as The Newtralizer, was a Salamandrian bounty hunter that debuted in the 2012 TV series. He is an enemy of the Kraang, the Ninja Turtles, the Utroms and later also ally then enemy of Slash and an ally to Lord Dregg. He is an amalgam of characteristics of a rejected toy design for Playmates Toys by Ryan Brown and a character created by executive producer Ciro Nieli whilst in elementary school. Due to The Newtralizer's costume, he is likely a parody of Marvel's The Punisher with inspiration provided in part by Judge Dredd. The most obvious feature in this respect is the skull-like pattern on the Newtralizer's chest that resembles the emblem on the chest of the Punisher's costume. (See also "The Good, The Bad and Casey Jones "for a similar homage/parody)
