Danny (who prefers to be referred to as "Daring Danny X") is a 10-year-old boy who made his debut in "Pups Save Daring Danny X". He was motivated to become a daredevil by a stunt Ryder performed during a rescue.
He was an ordinary kid until he saw Ryder jump over the shore riding his ATV. Since then, he modified his trike to go extra fast and perform dangerous jumps, and he gained the courage to attempt such stunts. He also modified his snowboard in "Pups Bear-ly Save Danny". His biggest endeavor was to jump over Rattlesnake Canyon, however he failed and was rescued by the PAW Patrol.
Danny is rambunctious, energetic, and always on the move. He can be somewhat reckless because of his daredevil attitude and personality. As a result, he often has to be rescued by Ryder and the PAW Patrol. He also has a tendency to ignore advice about the danger of his stunts from others, which others (such as Ryder and Mayor Goodway) find annoying. He seems to have toned down his dangerous stunts in the later seasons.
He can be dimwitted sometimes; in "Pups Save the Runaway Turtles", a turtle landed on his helmet which blocked his vision, but he tried to blow it off instead of stopping his bike.
Despite his flaws, he has a great amount of respect for Ryder. Seeing Ryder perform a stunt during a rescue inspired him to become a daredevil. He also sometimes apologizes when his stunts cause trouble for others.
Danny has pale skin (suntanned as of Season 8) with freckles, brown eyes and messy orange-red hair. He wears a yellow-orange shirt with a huge X in the center, a bracelet on both wrists, faded blue pants and black boots. Danny also has a black and red helmet with yellow X's on the side and center. He has a gap between his teeth.
