the core (amphibia)
Warning, heavy spoilers follow!
The overarching antagonist from the cartoon Amphibia. It was an amalgamation of the "greatest minds" (leaders, scientists, and so on) of Newtopia and the true leader of its raider civilization. After its defeat at the hands of both the main characters and many others, it tried to destroy its own planet out of spite, but was destroyed by the main trio for good.
When possessing the main character Marcy, The Core and its host were called "Darcy"
