Bankirosu is a vile, spiked Sea Dragon.

His origin is unknown, but he say's that he was born in the southern seas.

He like's to cause pain to large sea creatures, for example: Sperm Whales, by rolling up into a spikey ball and ripping up their intestinal tissues.

Thankfully, Doctor Starfy is here to prescribe a dose of heroism!

Bankirosu was last seen in Gigaton Trench.
