Ogopogo, also known as Tidarithian, is an enemy from Final Fantasy IV. It uses a strong Water spell called Deluge, which calls forth massive waves that will decimate the party. After its defeat, it will drop the powerful Masamune. It starts the fight by using Deluge twice.
[view·edit·purge]Ogopogo is the name of a cryptozoological creature reported to live or have lived in Lake Okanagan in British Columbia, Canada. Like the slightly more notable Nessie of Loch Ness, Ogopogo has never been identified as an actual living creature with any degree of scientific certainty, but the creature is nevertheless a popular tourist phenomenon.
Its Japanese name is possibly a portmanteau of "Tidal" and "Leviathan."
