Leo de la Iglesia is a Mexican-American figure skater who competes for the United States in the anime Yuri!!! on Ice. Born on August 2, he is nineteen years old and stands at 167 centimeters. He is known for creating his own choreography, a talent that sets him apart and earns him recognition for originality in his programs. On the ice, Leo delivers expressive, crowd-pleasing performances that reflect his energetic and creative nature, even though he does not include quadruple jumps in his routines compared to many of his top-tier rivals.

Off the ice, Leo is described as full of originality and considerate of those around him. He maintains an active social media presence and enjoys interacting with fans and fellow skaters. He approaches competitions with a strong sense of enjoyment and a desire to entertain, and he is willing to adjust his programs to suit different events. Leo deeply values his friendships and often thinks of his friends while performing. He looks up to Victor Nikiforov, another skater who also choreographs his own programs, as a source of inspiration.

In the competitive arc of the series, Leo wins gold at Skate America but struggles at the Cup of China, where errors in his free program cost him a podium finish. Despite this setback, he remains a spirited and adaptable competitor. His role in the story is that of a supporting rival, representing the depth of international talent in the Grand Prix circuit. His development is subtle, centered on his consistent passion for skating and his ability to bounce back from disappointments. Notable abilities include his independent choreographic skills, his knack for connecting with audiences through expressive routines, and his cheerful, sportsmanlike presence among his peers.
