Vaati
For The Legend of Zelda: A Link to the Past & Four Swords on the Game Boy Advance (GBA).
Stage: Vaati's Palace
From the official guide
The climactic struggle to defeat Vaati, the wind mage, demands that all heroes be involved for the long haul. To vanquish Vaati, players must throw bombs into his wind vortex, then detonate them when they rise near his main body and before he hurls them away. When he falls, strike him with your sword. He may rise and fall on the winds a few times, but eventually you'll ground the powerful mage—but he has one more cyclonic trick up his sleeve. . . .
