Bismarck Esper roaming oceans

Bismarck is a large, white or light blue, whale-like creature.

Bismarck was one of several espers captured by the Gestahlian Empire during their first raid on the esper world. The captive espers were taken to the Magitek Research Facility at Vector, and for sixteen years they were experimented on and had their magic drained to develop the Empire's Magitek army. The returners took many Espers magicite away from the factory.

After aiding Terra and the Returners on their journey Terra used her position of power with the Espers to convince phoenix Esper to revive all those that where doomed in the magicite factory.

Bismarck was granted to live out his days freely and choose to remain on a Hycean ocean planet that accepts him as sole protector of the planet.
