but is kyogre a dinosaur

Kyogre is most likely based on the Hebrew legends of Leviathan, the unconquerable primal master of the sea. Its counterparts were Behemoth and Ziz. Just as Kyogre is in conflict with Groudon, it was said that at the end of time Leviathan and Behemoth would start a battle that would kill them both. Kyogre's appearance also draws inspiration from a Orca. Kyogre could also be based on Hayo and Lakandanum, the gods of the sea of the Philippine mythology.

He's a fucking mythical beastie, even better.
