Mezool is depicted in vibrant purple armor with dark accents and flowing organic panels that resemble sea creatures. The S.H.Figuarts rendition faithfully reproduces her segmented armor, the glossy finish highlighting the sculpted ridges and the jointed limbs that invite dynamic posing. The figure showcases a sturdy belt with miniature medal slots and authentic emblem details that match the anime design. Her multi-part hands allow gripping poses and expressive gestures, while the extra accessories include alternate hands for attacking stances and relaxed poses. The paintwork emphasizes the contrast between deep purple, violet highlights, and metallic silver joints, yielding a striking, collectible display piece.

Mezool is one of the Greeed, a race of mysterious beings who awaken when their wraith medals are claimed by humans. In Kamen Rider OOO, she embodies the predatory elegance of the sea creature-based faction and uses her power to gather Medal medallions, fueling the darker side of the OOO belt and its metal-based fusion system. Her intelligence and calm demeanor contrast with the more impulsive characters, making her a formidable strategist in the ongoing clash with Kamen Rider OOO and his allies. Through pursuit, manipulation, and sudden bursts of raw power, Mezool drives key plot twists that challenge the hero’s resolve and reveal the complexity of the Greeed threat.
