Lleó de foc leads Jadow under the codename "Inferno Lord," wielding a flame and claw-based combat style. Identified as Frost Tiger's brother, he faces consistent annoyance when Joe mistakes him for a dog. Following Jadow agent failures, Lleó de foc confronts Joe, developing a personal grudge after Joe extinguishes his fiery mane in their first battle and repeatedly calls him a dog. This establishes him as one of Joe's most formidable adversaries. Lleó de foc also questions Alastor's loyalties within Jadow, displaying independent critical thinking. When Joe infiltrates Jadow headquarters, Lleó de foc attempts to overpower and eliminate him. Alastor intervenes, restraining Lleó de foc as both plummet into the void surrounding the base. Lleó de foc later surfaces in a snow-covered kingdom ruled by an ice princess. Hiding his fiery nature to preserve their relationship, he becomes her knight. His brother, Frost Tiger, attacks the kingdom; Lleó de foc engages and defeats him, though the victory brings sorrow. Recognizing his fiery essence is incompatible with the ice realm, he departs. Lleó de foc utilizes fire-based attacks, including hurling flaming meteorites and breathing walls of flame. His dialogue reflects pride and identity, such as demanding recognition: "So you're the one whose been knocking down Jadow members like dominos!" and asserting: "I'm a LION, not a dog! What's the matter with you?!"
