Captain Syrup is the captain of the Black Sugar Gang and Wario's primary rival in thievery. Her base of operations is Kitchen Island, from which she sailed her former pirate ship, the SS Tea Cup. In Wario Land: Shake It!, she commands the ship Sweet Stuff.
Captain Syrup made her debut appearance in Wario Land: Super Mario Land 3. In this game, the protagonist, Wario, still reeling from his defeat at the hands of Mario and the loss of his castle, sets out to find new riches. Wario decides to make his fortune by stealing all the treasures he can from someone else, which ended up being Captain Syrup.
Captain Syrup returns in Wario Land II. She leads her pirates in a raid on Wario Castle and steals all of his riches. As such, Wario returns to Kitchen Island to retake all the treasures that were stolen from him. Wario battles Syrup several times during this adventure, compared to just once.
Captain Syrup returns again in Wario Land: Shake It!. She is first seen robbing the Ancient Globe from a museum, which she uses to observe the kidnapping of the Merfle tribe within the Shake Dimension. She finds out the existence of the Bottomless Coin Sack, which is in possession of the evil Shake King. Desiring the treasure but not wanting to get it herself, Captain Syrup sends a Merfle to give the Ancient Globe to Wario. The Merfle persuades him to enter the dimension with the promise of treasure, sending Wario on a quest to unknowingly retrieve the Bottomless Coin Sack for Captain Syrup.
Syrup appears in several manga, sometimes as a major character in certain story arcs. These include GO Ketsu Wario, Mario no Bouken Land, Ore Dayo! Wario Dayo!!, Super Mario (Kodansha), and Super Mario-kun.
