Su in One Piece

Su is a small, fox-like creature that the Straw Hat Pirates encounter on Skypiea. Initially curious about the creature, Zoro asks about it, and Conis, a Skypiean, introduces both herself and Su to the crew. Su joins the crew for dinner at Conis' home and later observes the Straw Hats' activities in Skypiea.

During the events in the Upper Yard, Su is seen sitting with Conis, Pagaya, and Gan Fall, discussing the situation on the island. Su also enjoys some of Pagaya's pumpkin juice. Later, Su rides in a dial boat with Conis, Pagaya, and Aisa, falling asleep during the journey.

When the crew meets Nami, Su is asleep on the deck of the Going Merry. Su is asked by Pagaya to keep watch on the ship. During the attack by Enel, Su calls out loudly to alert Conis and Pagaya. After Pagaya is injured, Conis leaves Su in charge of watching Sanji and Usopp below deck.

Despite Su's attempts to convince Sanji and Usopp not to leave, they decide to help Monkey D. Luffy fight Enel. When Conis returns, Su is worried, trying to inform her of their departure. Su comforts Conis, who blames herself for involving the Straw Hats in the conflict with Enel.

As the Straw Hats prepare to leave Skypiea, Su, along with Conis and Pagaya, sees them off. Su plays a part in the emotional moments as Conis expresses her desire to be saved by Luffy and his crew, and later witnesses the crew fulfilling that desire.

Su demonstrates a level of intelligence, understanding Pagaya's commands and being able to communicate through gestures and mimics. She also exhibits personal preferences, such as liking pumpkin juice, as seen when she drank some that were left unattended by Pagaya.

Su has a solid white (purple in the anime) fur color with squinted eyes and average-sized ears. Her mouth resembles a snout and has never been shown open. Su's tail is long compared to her body, with a lighter color at the end

Su does not possess any special abilities.

Su has a strong bond with Conis, often seen in her arms or by her side, and she seems to love and comfort her owner. Conis, in turn, trusts Su, leaving her in charge of important tasks, like watching over Sanji and Usopp.

Pagaya also trusts Su, leaving her in charge of keeping watch. However, Su can get frustrated with Pagaya, especially when he misinterprets her attempts to warn him.

In addition to the One Piece manga and its anime adaptation, Su also appears in the following games as a non-playable character:

• One Piece: Grand Battle! 3

• One Piece Bon! Bon! Journey!!

Su also appears as a playable character in One Piece Treasure Cruise alongside Conis.

• Su's name is inspired by the sound "su" that she makes.

• Su and Nami share the same Japanese voice actor, Akemi Okamura.

• Aburaage is Su's favorite food.
