Si Young-jun

Si Young-jun (시영준) built one of the most immediately recognizable low-register voices in Korean dubbing. Audien's artist profile places him in the 4th class of the CJ ENM Voice Actors Association in 2000, and the credits attached to that page explain why he still lands instantly with fans: Giroro in Keroro, Might Guy in Naruto, and Volibear in League of Legends all carry the same weighty vocal signature.

That consistency is what keeps him valuable. Si has worked across animation, games, narration, and commercial voiceover without flattening the personality of the performances, which is harder than it sounds. In the Korean dub of David, he voices Goliath alongside Park Bo Gum, Song Jun-seok, and Jang Kwang. HITKULTR should frame him as one of the dependable specialists Korean localization casts reach for when they need size, menace, and instant recognizability.
