Crystallization was first introduced in the Saturday Morning Cartoon and utilized by Nagus and associated with the Void.
Even if you argue that the concept is distinct from roboticization, crystallization was first introduced in Western Sonic media as well.
If you're seriously going to entertain villains that aren't Eggman for speculative purposes, Nagus is a worthy contender.
It's over for JP purists. The JP manga just directly borrowed concepts from Western Sonic material that SEGA owns.
