Swiper is the main antagonist in 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.
