Description
Cap is a duelist and rival to Joe Kirifuda, introduced in the Duel Masters! season. He presents as an early-teen boy with blue, water-like hair. Initially, he wears a blue jacket, white undershirt, green-striped pants, and light yellow sandals. During the 10 Kings arc, his attire shifts to a headless cap, dark green sweater, lime green pants, and sandals.

Personality-wise, Cap embodies Water Civilization traits, respected in his homeland for research and database analysis skills. He detects dimensional abnormalities and travels via waveboarding. Sociable among masters, he handles non-threatening defeats gracefully. Significant conflict arises with his twin brother Gap over protecting Water Civilization lands, escalating during battles against Ze-ro.

Cap's background reveals he is a designer baby created by Mother Brain. After Zeron's defeat, Gap sacrifices himself to shield Cap from Mother Brain—a pivotal event shaping Cap's trajectory.

In duels, Cap employs Gacharange Creature spam tactics alongside Joe, Kira, and Bolts, wielding the signature "Papara Para Para Paparira Paradiso Draw." His deck evolves across series: in *Duel Masters!*, he uses a Water-based Super Gacharange Big Wave deck; in *Duel Masters King*, it shifts to Water/Nature with Team Wave focus; by *Duel Masters King!*, it features Water Civilization RexStars race creatures supplemented by Team Wave.

Cap's duel record spans multiple series. In *Duel Masters!*, he achieves 6 wins and 3 losses across 9 duels—victorious against Kindaichi Hakase and Gaia Hazard but defeated by Joe and Gap. In *Duel Masters King*, he defeats Agari and Godai but loses to Joe and Zero Jr. During *Duel Masters King!*, he overcomes Esper Magi and Crysd, Sea Dragon God.

In *Duel Masters King MAX*, Cap transfers to Joe's school, becoming a regular alongside Kira. He manifests "King Manifest" in the human world, aligning with Joe. Though he duels off-screen, he executes a direct attack using Code:-MAX. His development integrates him into the human world, maintaining partnership with Joe while honoring Gap's sacrifice through ongoing protective actions.
