Other weird ideas include: MechaGodzilla and Godzilla wipe out a flock made up of 100 Rodans with Rodan, Firebird, Quetzalqoatl, and another Rodan being the survivors, Baragon, Manda, Varan, and the original monsters from Godzilla Trading Battle are a violent cult worshiping Yamata No Orochi, Gigan's species being sentient, and the existence of a underground world similar to Hollow Earth (it's not at the center of the earth tho).
