Barba

Barba was the guardian of Three Eye Rock Palace, where Link recovered one of the six Magic Crystal shards necessary to rouse Princess Zelda from her unnatural slumber. It breathed fireballs at Link. However, it could be beaten if Link used the Jump Spell when it came out of it's lava and struck it in the head.

Volvagia
Barba bears a remarkable resemblance to Volvagia, the dragon boss in the Fire Temple of Ocarina of Time. Not only qua appearance, but qua name as well. Barba's Japanese name is Barubajia and Volvagia's Varubajia. In written Japanese, the "V" and the "B" are the same letter.
