Description
Jacqueline Muscle, daughter of Harabote Muscle and younger sister of Ikemen Muscle, hails from Planet Harabote. She possesses bright pink hair that falls below her shoulder blades, bright green eyes, and a distinctive head fin studded with three jewels—a common trait among natives of Planet Kinniku or Planet Harabote. Noted for her striking beauty, she stands 175 cm (approximately 5'9") tall, weighs 58 kg (approximately 128 lbs), and has a curvy figure, often showcased in revealing outfits.

Her personality initially manifests as bloodthirsty and sadistic; she revels in violent matches and the sight of blood. A natural show-person, she excels at captivating crowds and drawing attention. This early demeanor includes antagonism toward others, a tendency to break promises, and a temperamental nature. Her own brother remarks that she is “pretty on the outside” but “ugly on the inside.” She enforces rules with strict precision, wielding extensive knowledge of wrestling regulations down to specific articles and paragraphs.

A profound shift occurs during the finals of the Chojin Olympics. Witnessing Kevin Mask’s excessive brutality and having Mantaro Kinniku block an attempt to throw blood in her face, she comes to understand the true emotion and stakes of matches. This moment teaches her that bloody spectacles are not enjoyable and reveals the meaning of being a Justice Chojin and the power of friendship. She grows kinder and more supportive, evolving from a background presence into a strong supporting role within the main cast. She develops a distaste for the sight of blood, recognizing it as precious life-force, and becomes emotionally supportive of others.

Her relationships reflect complexity. With her brother, Ikemen Muscle, she shares a sibling rivalry underpinned by underlying trust and affection; their interactions are often physically rough yet caring. She forges a close friendship with Rinko Nikaido—a bond that develops from initial friction into an inseparable partnership where they frequently act in unison. Her dynamic with Mantaro Kinniku begins with his one-sided infatuation. Her affection for him grows gradually across the Chojin Olympics as she observes his bravery and growth, transforming her into a steadfast supporter who attends his matches and offers both emotional and practical support, though the precise nature of her romantic feelings remains ambiguous.

She first appears during the Chojin Olympics: The Resurrection arc as a spectator and unofficial presenter. Initially favoring Kevin Mask, she is chastised by him and later intervenes in matches to enforce rules, even threatening his disqualification to maintain order. She is unveiled as the mastermind behind the Punishment X Ring. Her pivotal transformation occurs when Mantaro protects her from having blood thrown on her, cementing her support for him.

In the Demon Seed arc, she forms “The Army of Idols” and actively works to prevent Mantaro from engaging in unwinnable battles. She provides logistical aid, including helicopter medical evacuations and transport, alongside consistent emotional support to characters like Mantaro and Rinko. She attempts to reconcile Mantaro and Kevin Mask and publicly champions the value of friendship between Chojin in Shibuya Square.

During the Ultimate Chojin Tag Tournament arc, she appears at award ceremonies and engages in discussions with other characters. She volunteers to travel back in time to care for Kevin Mask and offers her safer seat to Mantaro out of concern for his well-being. Upon discovering her brother’s selfish gambling plans, she criticizes him. She assists her stowaway friend Rinko by helping her board and sharing her seat, and takes on the practical role of piloting the timeship after the main team abandons it.

Her physical attributes include a Chojin Power of 60,000.
