Zuikaku is depicted in Kai Ni Battle Mode as a poised, battle-ready fleet girl. The figure combines a sleek, armored look with elegant lines, featuring enhanced shoulder guards, reinforced chest plating, and deck-like wing structures that sweep back from her sides. Her attire blends white and navy blue with gold trim, a long blue scarf or ribbons fluttering behind her, and period-appropriate naval accents that hint at her carrier origins. The piece sits on a dynamic base that evokes an air deck, with subtle weathering and metallic sheen on the armor and weaponry. Her hair is long, with a soft gradient from light brown to darker tips, arranged to frame a focused, determined expression. The overall composition conveys motion and authority, as if she has just signaled her squadron for takeoff and stands ready to lead them into battle.

Zuikaku is one of the storied ships of the Kantai Collection universe, a carrier who fights alongside her sister Shoukaku as part of the Combined Fleet. In-game lore and fan lore alike, she embodies loyalty, steadiness, and a calm leadership that keeps her air group cohesive under pressure. As a Kai Ni upgrade adds more powerful air operations, Zuikaku gains enhanced durability, improved anti-air defenses, and a more confident demeanor that mirrors her growing experience in battle. Her adventures span campaigns across the Pacific, coordinating strikes, escort duties, and the defense of allied ships. Her bond with her crew and commander underlines her role as a dependable flagship whose resolve inspires her fleet to press forward during difficult operations.
