K’Vathrak

K’Vathrak formerly known as The Newtralizer was an enemy of the Turtles and The Kraang.
Unlike his canon counterpart, he eventualy becomes an ally and helps to take down the Kraang, he also takes 2003 Leatherhead's place in the series.
==Appearance==
The Newtralizer is a heavily armored, alien Fire Belly Newt. 
He is primarily black, with an orange underbelly. 
The coloration of his underbelly forms a skull pattern. 
The Newtralizer is very muscular and bulky, easily dwarfing the Turtles in combat. 
He appears to be very intelligent, capable of using Kraang equipment and weaponry without issues.
His armor set includes a belt, a pair of shoulder plates (the right plate is far larger than the left), two straps that connect the belt and shoulder plates, a pair of armored bracelets, a pair of leg holsters with pouches and ammo types attached to them, and a pair of axe blades attached to his tail. 
He also wears a backpack with an antenna sticking out. 
It is likely a radio, but its exact purpose is unknown. 
He also carries three Kraang tentacles as trophies tied to his belt.
== Personality ==
In Operation Breakout, the Newtralizer was shown to be very resentful to the Kraang due to being imprisoned and tortured, heavily aggressive, attacked anything on sight, and a mute. 
in Newtralized his personality was fleshed out more, dropping the mute quality, and also expanding on his deep hatred of the Kraang, showing that he cares little for anything, or anyone that gets in his way of destroying them, even innocent people, but when reunited with his wife, he changed his ways and has shown to be loving husband and future father.
== Skills & Abilities ==
Like most aliens in the series, he has high intelligence, enough to speak, very efficiently operate advanced weaponry, and to quickly adapt to changing combat events. 
Despite his intelligence, only with the help of a universal translator was he able to speak the human's language to communicate sufficiently with Slash. 
His weapons include lasers, missiles, sawblades, exploding mines, and he also has blades attached to his tail. 
The Newtralizer is capable of constricting a foe with his tail, and able to eat a Kraang, minus the armor, whole. 
He possesses incredible strength and speed. 
He is also shown to be quite durable, having an extremely high resistance to physical damage with or without his armor, as he was able withstand attacks from numerous Kraang lasers, Leo's katana, Raph's sai, even after getting crushed by Mikey attempting to drive a car, he still survived without any visible dents, bruises, scratches or an injury of any kind. 
He probably also benefits from an enhanced regenerative ability that helps him to shake off any internal injuries and injury trauma.
