Personality
Newtralizer is shown to be the most serious and antisocial member of the Mighty Mutanimals. Though loyal to his team's cause and faithful to his comrades, he is by far the least approachable member of the team and usually doesn't trust anyone outside his circle of allies unless he is given reason to.

Due to having spent the majority of his young life suffering at the hands of the Kraang, Newtralizer was initially soley fixated on extracting revenge on the ones who had brought him so much pain. Though he was able to recognize and willing to help and work with those who also faced suffering by the Kraang, specifically his original partner Slash, Newtralizer's dogmatic obsession with achieving his goals had also made him completely apathetic towards the potential casualties caused by his actions and even willing to harm potential allies that shared his abhorrence for the Kraang; qualities that caused for a bad falling-out with the more principled and considerate Slash, who was strongly opposed to the idea of risking the safety of innocents.

Following this perceived betrayal, the embittered and hurt Newtralizer attempted to use his outrage over his falling-out with Slash as a means

Pre-Show
A member of a race of amphibious extraterrestrials known as the Salamandrians, the alien who would later be known as the Newtralizer was somehow transported to Dimension X where he was imprisoned by the Kraang and forced into a life of torture and misery at the hands of his tentacled captors. Growing to despise the Kraang with a vengeance for their maltreatment of him, the Newtralizer began a one-newt war against the brain-shaped aliens after arming himself to the teeth with a variety of bladed and energy weapons, yet was later re-captured and imprisoned in one of the Kraang's secret facilities on Earth after the Kraang decided he was too dangerous to keep in Dimension X due to his habit of eating every Kraang he defeated whole.

After accidentally being freed and given his current name by the teenage mutant ninja turtle Donatello, who had infiltrated the facility to rescue his friend and love interest April O'Neil's father Kirby, Newtralizer continued his crusade against the Kraang until he encountered and rescued the mutant tortoise Slash from imprisonment by the Kraang, leading to a partnership between the duo that was aimed towards finally ending the menace of the Kraang.
