Devil Z

A mysterious Destron deity who wants to create the Godmaster - a being who'd be able to harness all aspects of Choukon Power, with the help of his servants, Overlord and Black Zarak.

In the Legends manga, it's revealed that he was a byproduct of the Matrix of Leadership. Following the Transformers' rebellion against the Quintessons, they would get rid of the evil Quintesson powers contained within it, accidentally giving birth to a malicious entity, which would then name itself the Devil Zodiac (デビルゾディアック) and seek revenge for being cast out of its birthplace.
