Banica calls the Worldeater the "ultimate corpse soldier", while Lich and Eater are technically corpse soldiers but have the souls of forest spirits. Eater is also absent from the character profiles despite having a major role alongside Lich, so I find it very possible that Eater has shapeshifting powers and can turn into Worldeater.
