So, spoilers for AoE below this:
Are y'all gonna merge Galvatron with Megatron now that the film even explicitly stated "Different name, same bot underneath?"
Considering G1 Megatron and Galvatron have separate pages, even for the Sunbow cartoon which treated them as the same person...
This is because Galvatron can time travel and interact with Megatron, and navigating that kind of stuff in fiction sections is kind of rough. Also, because, dude, Megatron's page is big enough already? It doesn't need to be twice as large, and splitting off Galvatron just makes sense when managing the size of a page.
Movie Megatron--->Galvatron is strictly linear, and so doesn't have that problem. Same with the UT guys.
