Pre-Mega Man ZX Shippuden
Ancient Minister was once known as the Master Robot who ruled over the Isle of the Ancients with the rest of the R.O.B.s. Although the Island was originally peaceful, Tabuu wandered the surface of Dens alone for an untold number of years and the rest of the R.O.B.s. took pity and gave him shelter. Seeing potential in the collective species as the perfect, unquestioning servants, he granted them higher intelligence and physically shaped the species to suit his needs thus creating the ancient clan of the Sith for Momoshiki Palpatine in the process. Tabuu studied Ōtsutsuki's home planet and in turn established an army of humans and hylians. Tabuu have constructed the two titan size R.O.B.s to ensure the R.O.B. Tribe's transformation into a kingdom and eventually dubbed it the Robot King: Super R.O.B. and the Robot Queen: Mega R.O.B.

Tabuu had secretly had the R.O.B. factories constructed by Innominatus so that the King R.O.B. and the Queen R.O.B. can have total control of Tabuu's newfound army. Most of the R.O.B. brethren had taken over the Innominatus Tribe's duties in the R.O.B. factories so that their King R.O.B. and the Queen R.O.B. can concentrate on swearing their loyalty to Tabuu. Due to this, all the R.O.B.s had changed a simply structured hierarchy: Robot King and Robot Queen ruling over Robot Master and the lesser R.O.B.s that once served the Robot Master have served the Robot King and Robot Queen in return of giving Tabuu a massive army. A number of R.O.B.s. had to serve in his command of finding and taking the Triforce from the Kingdom of Hyrule were deployed into the world. Tabuu's disciple, Rock Ōtsutsuki had a large number of electric type Electric Type Pokemon, consisting of Pikachu, Pichu and Flaffy to power cities and factories. The rest of the R.O.B. units take part of the Konoha Republic's evolution into the new Galactic Empire.

The Ancient Minister was aware of the Super R.O.B. and Mega R.O.B.'s capabilities of controlling the R.O.B. brethren and began in secret seeking out the legendary Paul Gekko and his grandson to stop the Eggman Empire from ruling the multiverse.
