Swiper the Fox is the main antagonist of the Nick Jr cartoon kids show Dora the Explorer , and Dora's archenemy. He will always try to steal an object from Dora and Boots (sometimes another character), either succeeding in the scheme, or failing.

However, there have been a few occasions where he served as an anti-hero for the protagonists.

In the original series, he was voiced by Marc Weiner. In the 2019 live-action adaptation, Dora and the Lost City of Gold, he will be voiced by Benicio del Toro, who also played Dario in the James Bond film License to Kill, Jack Rafferty in Sin City, The Collector in the Marvel Cinematic Universe, and DJ in Star Wars: Episode VIII - The Last Jedi.

Biography
Swiper is a fox with orange and yellow fur and wears a blue mask and gloves. He is always an obstacle in Dora and Boots' adventures and he will try to steal anything from them (such as Dora's backpack). Whenever he shows up, Dora, Boots, and you the viewer, in order to stop Swiper from carrying out his task, must say "Swiper No Swiping!" Once this is done, he will snap his fingers in defeat and disappear (though there was tonetime he can't even get up due to being inside a hollow tree). However, there has been a few attempts where this pesky fox was successful in stealing. No matter, he does not necessarily keep the item he steals; instead he throws it away somewhere for Dora and Boots to look for it.

Appearances
Swiper's pelt is primarily an orange burgundy creme, with highlights on his eyebrows, the top of his snout, undercarriage, and the end of his tail. His white eyes and black pupils are concealed behind a blue do-rag/mask, matching his gloves. Swiper appears in almost every episode. His first appearance was in "The Legend of the Big Red Chicken". The very first episode that Swiper didn't appear on was "Te Amo".

Personality
Swiper best described as sneaky thief who in many of his appearances, he bullied Dora and Boots by stealing one of their key items and tossed it among the said items' lookalikes to make their adventures difficult. But much like Robbie Rotten from Lazy Town, his presence in a children's show restricts his success and cruelty as a villain to the point of being mischievous trouble makers. Nonetheless, he is a true nasty thief who capable in successfully stole key items should viewer, Dora, and Boots lowered their guard and their quest will abruptly comes into halt if he succeed, so it's worth to keep an eye on him.

It's not explained when and why he started his career as pesky thief, as the writers didn't want to give Swiper a detailed backstory on his stealing because they thought the show would be cleaner that way. Until a christmas movie, where it is revealed that he became a thief in his childhood, stealing toys from other which he finally realize that he does not want to be a thief all his life.
