Well... again again... Ben10 and Generator Rex mix!
Alpha nanite is sentient.. so I believe that the omnitrix could be set to copy it (like upgrade is made up of nano circuits etc.)
The omntrix version is called Meta-nite
(combination of Meta and Nanite)
Meta- (from Greek: μετά = "after", "beyond", "adjacent", "self"), is a prefix used in English (and other Greek-owing languages) to indicate a concept which is an abstraction from another concept, used to complete or add to the latter.
- from wikipedia.org
As well as a play on the name Meta knight - a character from Kirby's dreamland.
