Well I like the name and it is a multi-verse soooo, my side of the multi-verse decided to name them that.

Prefer that non-canon name for the race then just calling them Freiza race all the time.  As long as Chev has no problem with that of course in which case I can change that if needed.

As for the human part, Dr. Muyuu downloaded a ton of race information into his Machine Mutants so hurray for mad scientists!
