Ezlo

Ezlo was Link's main companion in The Legend of Zelda: The Minish Cap. Not only did he give hints at the ready by pressing Select, but he also gave Link the power to shrink whenever he goes nears a Minish Portal.

History
Ezlo was a former renowned Minish craftsman and master to his apprentice Vaati, who was working on a grand project: To make a cap that would grant the wishes of its wearer. No sooner had he finished the cap, then did Vaati steal it from his work desk and place it onto himself. Vaati used the power of the cap to make himself into what he claimed to be "the most powerful sorcerer."

Ezlo attempted to stop Vaati, but was unsuccessful. Vaati was able to use the power of the wish-granting cap to tranform Ezlo into a green bird-hat. Soon enough, our hero would find Ezlo in the Minish Woods being attacked, and befriend him for the entirety of a large adventure.

Abilities
While in a cap form, he had little power. His only abilities were giving information and hints to Link spontaneously and on demand, as well as giving background about the current situation. He could also shrink Link down to Minish-size when he stands on top of a Minish Portal, such as a Tree Stump or a rock.
