And one crucial detail not even the movie revealed: Marchosias, what is known today as the Hajiroboshi, is the Baklazan family Gundam that was lost during the Calamity War. I suspect this is damage control from Bandai and Sunrise for the people who are angry about revealing nothing in the movie. No buildup, no narration, nothing, just a last-minute printing of the Baklazan crest on the cape while in production.
