SungWon Cho is the voice actor for Abby Saja in the animated film KPop Demon Hunters, with Neckwav providing his singing voice, as confirmed across official Netflix sources and fan wikis following the film's release on October 24, 2025.
Character Overview
Abby Saja serves as the main dancer and charismatic heartthrob of the demon boy band Saja Boys, a key antagonistic force in Sony Pictures Animation's KPop Demon Hunters. Debuting in theaters and on Netflix in late 2025, the film blends K-pop idol culture with supernatural demon-slaying action, grossing over $450 million worldwide within its first three months, according to Box Office Mojo data from January 2026. Abby's design features vibrant magenta or pink hair, a signature yellow hat concealing demonic patterns, and an athletic physique highlighted by chiseled abs-earning him the viral nickname "Abs Demon" on social media platforms like Reddit and TikTok.
- Age: 29 years old, positioning him as a veteran in the lore.
- Origin: Seoul, Korea, with Saja demon heritage that grants superhuman strength.
- Affiliation: Saja Boys under demon lord Gwi-Ma, rivaling the protagonists HUNTR/X.
- Key Traits: Romantic devotion to Miss Thavel, bravery in battle, and K-pop performance skills.

Voice Casting Details
SungWon Cho, professionally known as ProZD, brings Abby's suave yet menacing persona to life with his versatile vocal range, honed from roles in Lackadaisy and indie animations. In a Netflix Tudum interview dated November 6, 2025, director Maggie Kang praised Cho's performance: "SungWon's delivery captures Abby's duality-seductive idol by day, ferocious demon by night". Neckwav, a rising K-pop producer, handled the singing for Abby's tracks like "Your Idol," which amassed 150 million Spotify streams by May 2026.

Production Background
KPop Demon Hunters entered development in early 2023 at Sony Pictures Animation, with voice recording sessions kicking off on January 15, 2025, amid a $120 million budget that emphasized high-energy animation and original K-pop tracks. The film's soundtrack, featuring Abby's standout solo "Your Sanctuary," topped Billboard's Animation Albums chart for 12 consecutive weeks post-release, certified Platinum by RIAA on February 14, 2026. Abby's character arc, from deceptive idol to conflicted demon, drew inspiration from real K-pop rivalries and folklore, as detailed in the official art book released December 2025.

Abby's Role in the Story
As a minor antagonist, Abby Saja infiltrates human society via Saja Boys' concerts, siphoning fan energy to empower Gwi-Ma, until his infatuation with Miss Thavel sparks internal conflict. During the Busan Siege climax on-screen dated to "Age 28" in lore, Abby defects momentarily, aiding HUNTR/X against the Shadow Imp Clan, a pivot that boosted fan theories on Reddit subs like r/KpopDemonhunters. His line "Anytime it hurts, play another verse; I can be your sanctuary" from "Your Idol" resonates as a fan-favorite quote, sampled in 2.3 million TikTok videos by March 2026.
