Wait Galvatron gets a combiner form?
Toy only. The American release came out alongside the Protectobots, but Cyclonus was the only figure in the combiner with the excuse that Galvatronus can steal limbs from other Combiners to make up for it. It probably won't have any bearing on the fiction.
It's kinda funny that the two most recent Galvatrons have been a Combiner and a Headmaster, considering IDW Galvatron's stances on both.
