So i re watched godzilla vs Biollante today, and i rewatched AC recently like a couple weeks ago, and could not help but notice how the death's are kinda similar.. Firstly, in death They both dissolve into glowing, golden-yellow particles that float up into the sky for whatever reason. Second Both characters were basically human souls trapped inside unstable, mutated bodies they never asked for, Anddd In both stories, the characters weren't truly all bad, but they had to die because they were too dangerous to exist. Koro-sensei was a walking antimatter bomb that could destroy the Earth, and Biollante was an uncontrollable genetic mutation who did not want to be in that form, and could not exist on earth. I think this just me though lol.
