Description
Hercule Barton, alias Elly, serves as a central character in the franchise. This 16-year-old detective student possesses a petite frame, standing 151 cm tall and weighing 46 kg, with distinctive violet hair and red eyes. Her full name intentionally references the fictional detective Hercule Poirot.

Extreme shyness and social anxiety define her personality, making her the Milky Holmes team's most passive member. She struggles to speak in conversations and becomes overwhelmed when others look at her; working as a posing model for an art center resulted in nightmares due to the artists' gazes. Despite this timidity, she sometimes attempts to act as the group's voice of reason, though her input is frequently ignored or dismissed. Notably, she possesses greater sexual knowledge than her peers, reacting strongly to suggestive situations—fleeing when asked to pose with her legs open or blushing intensely upon witnessing intimate interactions.

Her primary ability, called her "Toy," grants superhuman strength. While its full extent is rarely shown after an early loss in the series, feats include swinging a construction excavator like a baseball bat, lifting and throwing a whale, and temporarily blocking adversary attacks during crises. She is the only Milky Holmes member shown to briefly reactivate her Toy in high-stress situations, such as freeing Cordelia from a sarcophagus or confronting threats like Sheryl's levitated boulder.

Character development varies across media. In the main anime series, her shyness persists, but moments of determination emerge, like modeling to overcome fears. She displays crushes or admiration, notably addressing thieves Mary and Kate as "Onee-sama" after they save her, with hearts appearing in her eyes during interactions. She blushes while observing Cordelia and Nero Yuzurizaki, suggesting potential romantic interest in the latter. Non-anime media, like PSP games, depict her as more consistently competent, using her strength strategically in combat—blocking sword strikes or shattering large obstacles.

Within Milky Holmes, her relationships highlight her role as a supportive yet often overlooked member. She participates in group activities, including shared sleeping arrangements, and shows loyalty during investigations, like taking blame to protect a kitten or aiding Cordelia. Antagonist Henriette Mystère manipulates her, using false promises of restoring Toys to exacerbate the team's struggles.

A minor inconsistency exists in the spelling of her surname, occasionally listed as "Burton" in official merchandise.
