Patra is a mini-boss from the Legend of Zelda series. appearing first in the original game as one of the toughest foes in the last dungeon.
My memories of Patra are a tad blurry, but I remember Patra giving me a bit of trouble before Ganon.
Oracle of Ages featured his remade form with a new name Eyesoar. Never played the Gameboy Color Zeldas, so I missed his appearance.
