The Omega-1 Nanite (also known as the Control Nanite) is a large silver nanite that was injected into Rex by Dr. Rylander as a "present". When Rex asked Rylander what he had injected him with, Dr. Rylander replied that he had injected him with "everything".
The Control Nanite, as its name implies, controls the active nanites in Rex's body and is also the nanite responsible for the creation of Rex's new machines. The Omega-1 also has the ability to create new nanites and for this reason Alpha attempted to take the nanite from Rex in a plot to create a body capable of sustaining itself.
Alpha succeeded in absorbing the Omega-1 from Rex until he and Ben Tennyson used their combined powers to beat Alpha into submission and Caesar Salazar extracted the Nanite from Alpha and reinserted it into Rex.
