Jackson Jekyll
Jackson Jekyll is the son of Dr. Jekyll and a shy, studious student at Monster High who struggles with his dual identity as Holt Hyde.
Overview
Summary and key details about this Monster High character.
Jackson Jekyll is the teenage son of the legendary Dr. Jekyll, attending Monster High where he navigates the challenges of being half-human and half-something far more complex. Unlike many of his classmates who fully embrace their monster heritage, Jackson grapples with an extraordinary dual identity that makes his high school experience uniquely challenging. He represents the introspective, cerebral side of his split personality, preferring quiet study sessions over the chaotic social gatherings that other students enjoy.
Described as studious and shy, Jackson is the epitome of a thoughtful, intelligent young man who would rather lose himself in a good book or scientific experiment than engage in typical teenage drama. His catchphrase and personal motto reflect his desire for control and balance: he constantly reminds himself to "keep cool" and maintain his composure, even when his alter ego threatens to emerge. Jackson's "freaky flaw" is his inability to fully control his transformation into Holt Hyde, his fiery and rebellious counterpart who has completely different interests, friends, and personality traits.
In terms of fashion, Jackson tends toward a more conservative, preppy style with his signature colors reflecting his Jekyll heritage—often incorporating greens, purples, and blacks into his wardrobe. He typically wears glasses, neat clothing, and maintains a tidy appearance that contrasts sharply with Holt Hyde's wild, flame-themed aesthetic. His closest friends include Draculaura, Frankie Stein, and Clawdeen Wolf, who accept him despite his complicated nature.
