Melchizedek

Melchizedek is the name of a hypothetical biomechanical dragon. An extremely limited amount of legends have been written of it across the universe and, as a result, its presence and background are largely left a mystery.

It is first mentioned in Part III.

Name Etymology
The name "Melchizedek" is old Canaanite in origin, derived from the terms melek(h), which means "king", and ṣedeq, meaning "righteousness". Melchizedek, or Melchisedec in the King James Version of the Bible, was the name of a high priest who blessed Abraham.

The inspiration for the name of the dragon, however, came from its usage in the manga, Battle Angel Alita, in reference to a quantum supercomputer that is used to run the space elevator that holds the cities, Tiphares and Ketheres, in place. Melchizedek, throughout the manga series, was used to run Jacob's Ladder (the orbital ring) and also power Tiphares.
