This is Unicorn! · 7:18pm Mar 30th, 2020
Sadly, searches for "Princess Galvatron" and "Galvatron Unicorn" turn up nothing, but at least I got a consolation prize.
Context - the dub of the Japanese "Headmasters" cartoon was infamously bad, and someone on the team recognized Galvatron's plan to become the Unicron-sized "Grand Galvatron" was a reference to the planet-sized Transformer, but mistranslated his name as Unicorn, leading to Galvatron declaring he will become a unicorn.
The way Galvatron's voice actor says "parts" makes me uncomfortable on multiple levels. Though planet-belly Unicron helps.
It sounds like something out of a bad parody.
Headmasters is such a fucking trip.
And oh my god, that design's the awful, never-released G1 Unicron toy. :O
