Noah Nixon is the deuteragonist of Generator Rex. He is a human agent sent by White Knight to befriend Rex and subtly influence his decisions to make him more compliant. Noah eventually revealed to Rex his status as a covert agent and they became friends on open terms.
Biography
Noah is in every way a regular kid, except for one thing: he is secretly employed by Providence to be Rex's friend. This deception ultimately weighs heavily on Noah, who genuinely likes Rex. Noah provides a dose of reality and normalcy in Rex's life and is there for him, whether it's to play a game of basketball or to offer advice.
Abilities
It's eventually shown that Noah does in fact have his act together very well, being popular, intelligent, and surprisingly well-connected in school and life, as well as being a veteran, if not well-practiced, combatant. Rex, by contrast, is a clumsy goof around people his age. After going through some Providence basic training (even though he technically dropped out) he's shown the ability to use the Providence assault rifle and even hammered Van Kleiss with a forklift.
