Galvatron is in china and the Dinobots as well. since optimus vaguely gave them freedom and galvs needs a new army. I expect galvatron to attempt to turn them to decepticons. Imagine galvatron riding grimlock into battle against optimus prime lol. It obviously has precedent. G1 Sunbow, Dreamwave,animated. Regeneration one, aligned and even beast wars vaguely.
