Diego Márquez is an 8-year-old Latino action-adventure hero with a big heart. His goal is to save and protect the animals and their environment. Athletic and fearless, he is always at the ready no matter what the situation. Diego loves learning new things. He takes a scientific approach to problem-solving and also uses a variety of high-tech gadgets and gizmos to save the day.


Diego is Dora's cousin. Though it's never confirmed how they're related, they're presumably first paternal cousins considering they share the same last name (i.e. Dora's father and Diego's father are siblings). Like Dora, Diego comes from a family of three kids, with the three kids consisting of himself and two daughters. However, while Dora's the oldest kid in her family (her younger brother and sister, Guillermo and Isabella, are fraternal twins), Diego's the youngest kid in his family (he has two older sisters named Daisy and Alicia). While he's a supporting/minor character in his cousin's show, Diego's the host of his own show where the opposite happens (Dora appears as a minor character). He can also speak both English and Spanish, just like his cousin.


Diego has dark-tan skin, brown eyes, and brown hair.

In his debut on Dora the Explorer, he originally wore a dark blue shirt with a tan vest, green cargo shorts, green socks, brown shoes, and a silver watch.

In the first three seasons of his show Go, Diego, Go!, he wears a lighter blue shirt with the same vest, darker blue cargo shorts, white socks, gray shoes, and a blue and yellow watch. This version of his outfit reveals that his vest can transform into a long sleeve vest, a lifejacket, or maybe even both.

However, starting in the fourth season of Go, Diego, Go!, he wears a short-sleeved red sweatshirt with an orange top underneath, black cargos, white socks, and black and red sneakers. Diego is seen wearing his previous outfit in a few flashbacks in the episode Fiercest Animals.

In Dora and Friends: Into the City, Diego switches back to his outfit from Seasons 1-3 of Go, Diego, Go!, but it receives a few changes: He retains his light blue t-shirt, but his tan vest now has dark blue trim, lacks pockets, and his Animal Rescue badge is now on the right side of his chest. His dark blue cargo shorts are shorter and have smaller pockets, he discards his socks, and now wears a new gray pair of converse sneakers with orange laces. He keeps his video watch, and his rescue rack now rests on his left shoulder.

Diego appears in several episodes of Dora the Explorer as well as every episode of Go, Diego, Go!. He had a major role in every episode except in "Alicia Saves The Crocodile" and "Alicia and Whitetail to the Rescue". His first appearance in general was in "Meet Diego!".
