Chibicons

Chibicons are the ancestors of the Decepticons. Led by Tabuu Ōtsutsuki also known as Deltatron, The Chibicons had one goal, establishment of the Galactic Eggman Empire on top of the Mushroom Kingdom and the Kingdom of Hyrule and the multiverse.

Foundation
In the Golden Age of Humanity Chibicons began life as a line of R.O.B.s being created by Professor Rudolf. Following the establishment of the Galactic Empire, lusting for power, the Chibicons, as they now called themselves, rallied under a leader, "Deltatronus" and began a war with the Galactic Empire and the New Republic, who proved unable to match their inborn military skills. After the fall of several successive leaders of Free Planets Alliance, the heroic robots turned to stealth, and invented the art of transformation; with this edge, Yang Wen-li ended the war and ushering in the prosperous Golden Age of the Multiverse.

Cybertron Incident
Over time, the defeated Chibicons married transformation technology with robot mode flight powers, leading to the creation of "Deltatron" around nine million years ago. Gathering like-minded warriors like the loyal Soundboom, the emotionless Shockblast and the young upstart Starsceech, and brain-washing others into his service with the Robo-Crusher, Deltatron slew Yang Wen-li. For whatever reason, the aggressive actions of Deltatron and the Chibicons were not made public knowledge, and young children like the naive Okita Gentatsu still looked up to and his followers because of their flight powers.

However, Gentatsu soon learned the error of his ways when Deltatron about the possibility of using one of the local warehouses for storage, only to turn on Gentatsu once he had gained access to the energy stored within the facility. Deltatron fatally injured Gentatsu in a scuffle and left the young child to die in space while he set about pillaging and battling the Resistance, killing Leia in the process with Paul Calrissian killing Mon Mothma in the process allowing Chandrila to become a barren wasteland of nothing.
