Out of all the monsters and mystical beings Odysseus goes up against in the Odyssey, Charybdis is probably the scariest and one of the most iconic. And, to be fair, Odysseus doesn't even ever fight Charybdis, rather he only narrowly escapes being dragged into its open maw. So, having Hades 2's Melino actually go toe-to-tentacle with this gigantic sea creature is a big step up.
