This toy has many undocumented features in the form of small moving parts that play no role in either mode; most conspicuous are two articulated feet for the tank mode. In one of the Hasbro Q&A sessions, it was confirmed that these are remnants of an early design version of Galvatron, which would have been at a larger size class and featured a third mode as a "walking tank." It is still possible to manipulate his parts into a mode greatly resembling the original concept design. Galvatron participated in battles against a variety of opponents, both Autobots and Decepticons. Sometimes there were many of him! He appeared in three different bodies, all in the "Galvatron" event:

In the subsequent Golden Age, Galvatron became one of Nova Prime's closest friends and advisors. All Good Things He later served on the first Ark, part of Prime's dream of expanding Cybertronian domination throughout the cosmos. However, Galvatron and the crew were lost when he plunged the ship into the mysterious anomaly in the Benzuli Expanse, a selfish act that killed the rest of the crew. Undead, Galvatron became the herald for Nova, now known as Nemesis Prime, ruler of the Dead Universe. As the only member of the crew who could survive the living universe for any length of time, he was sent to secure the inactive Thunderwing Spotlight: Galvatron and to prevent any interference with their plans for Earth.

Megatron led the Decepticons in the war for the Mini-Cons, moving from Cybertron to Earth in his unstoppable goal to seize the power of the tiny 'bots. His relationship with his lieutenant Starscream was a troubled one, his harsh abuse of the younger Decepticon earning him his undying enmity, while his rivalry with Optimus Prime was an odder one still: when the Autobot leader was thought dead, Megatron sank into a deep depression, seeing no further challenge in his life without his eternal foe. Once upgraded through the power of the Mini-Cons into "Galvatron", Megatron was tormented further by the emergence of the threat of Unicron, whose existence called into question all he had ever fought for. Unable to tolerate the idea of living in peace, Megatron sacrificed his life to destroy Unicron. HARNESS THE POWER OF ENERGON: Gear up the most powerful substance on Cybertron, Energon!

In one possible scenario that ensued, Galvatron happened upon the Autobots already at the coast, in the middle of hauling the ship out of the water. Galvatron blasted both the ship and the sphere, ensuring that the Autobots would not have access to its secrets, and then began raining down Decepticon firepower upon his foes. A Galvatron Action Master was planned at one point, but apparently went no further than a concept sketch. It is only vaguely similar to Galvatron's normal appearance and may possibly have been a "powered up" Galvatron of some sort.
