Obli

Obli is a character from The Wind Waker who can be found at the Flight Control Platform. While he might look like a Rito, he's actually just a human who dresses up as one of the feathered race due to his unhealthy obsession with them. He soon began running the Bird-Man Contest along with his younger brother, Willi.

Trivia

 * An interesting thing to note is that Obli mildly resembles Waluigi from the Mario series.
