The Bake-kujira (化鯨, literally “ghost whale”) is a mythical Japanese yōkai (ghost, phantom, or strange apparition) from western Japan. It is supposedly a large ghostly skeleton whale and is said to be accompanied by strange birds and fish.

I wonder if Titanosaurus will be on Godzilla’s side.

Interestingly,  looking around the Bake-Kujira or ghost-whale was a kinda obscure Japanese supernatural creature prior to days of internet. So that seems very thematically good choice for the sleuthing of myth that appears to be being set up.
