Guzzlord’s mouth isn't a biological stomach or a black hole, it's an active, open Ultra Wormhole. Think about it, the Pokédex explicitly states that despite devouring entire mountains and buildings, Guzzlord produces absolutely no droppings. It’s being teleported across dimensions. This completely changes the tragedy of the untrained female Faller from 10 years ago. When Looker froze and Guzzlord 'consumed' her, it didn't end her life. She was actually pulled directly through the wormhole inside its jaws and safely deposited onto a completely different, peaceful parallel world in the multiverse. Looker and Nanu assumed the worst because they didn't understand Ultra Space science yet, but she’s actually out there right now, alive, whole, and safe in an unknown timeline.
