Full Name: Swiper Marquez
Birthdate: May 2nd, 1993
Swiper is the main antagonist of the television series 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.
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! Ha, ha, ha!!" Swiper is a baby show character from "Dora the Explorer."
