Swiper the Fox is the main antagonist of the television series Dora the Explorer and appears in nearly every single episode. He is a sneaky orange fox. As his name implies, Swiper steals or attempts to steal key items that help Dora on her adventures. Clever as he is, Swiper never manages to take Dora completely by surprise; an ominous "whisking" sound is always audible just prior to his appearances. He's voiced by Marc Weiner, who also voices Map from Dora the Explorer.
To prevent Swiper from success, Dora must repeat the phrase, "Swiper, no swiping!" three times. Usually she prevails, and Swiper slinks away, snapping his fingers and saying, "Oh, man!"; sometimes, however, Swiper gets to the item before Dora has a chance to repeat the phrase. He then gloats, "You're too late!" (and frequently "You'll never find it now!").
Swiper made a cameo appearance at the near ending of MYCUN as a police officer where Gabriel calls him to arrest Dora and Boots for liking Carrie Underwood. So, Swiper took Dora back to her family at her house in Puerto Rico, and also took Boots back to his family in the jungle of Puerto Rico.
