Nudge

Nudge is one of the members of Tetra's pirate crew in The Wind Waker. He is in charge of guarding Tetra's room on board the pirate ship and won't allow entry to anyone. He is as tall as Senza and Gonzo, but has longer hair than them. According to his Nintendo Gallery figurine description, Nudge counsels Tetra when it comes to making decisions since he's the one that understands her best out of all the pirates. However, despite this, he has a very minor role in The Wind Waker, and almost a non-existent role in Phantom Hourglass.

Nudge makes a final appearance in The Wind Waker during the game's ending. After Link and Tetra resurface from the sunken Hyrule Castle, Nudge, along with the rest of the pirate crew and a few other character, greet the pair aboard their pirate ship. Gonzo is then seen steering the ship as Link, Tetra, and the rest of the gang of pirates set sail from Outset Island in search of new lands.

Like the rest of the pirates, Nudge bears a striking resemble to a character portrayed in a wall painting hanging in the sunken Hyrule Castle, which hints that this character could be Nudge's ancestor serving under the orders of a past Princess Zelda.

Strangely, even though most of the pirates from Tetra's crew make an appearance in Phantom Hourglass, Senza and Nudge are the only two members of the gang who are nowhere to be seen in the game, but it is safe to assume that they're still with the other pirates.

Trivia
The character corresponding to Nudge on the wall painting in Hyrule Castle shares similarities with Renado from Twilight Princess.
