About Chris
Chris Guerrero is the English voice actor behind Ainz Ooal Gown in the English dub of Overlord. His performance became one of the most celebrated dub portrayals in modern isekai anime, largely because of the immense gravitas he brought to the Sorcerer King while still preserving the character’s dry humor and moments of insecurity.
Guerrero’s voice work helped make Ainz instantly recognizable among English-speaking anime fans. His deep, resonant delivery gave the character an intimidating presence that matched the visual scale of Nazarick’s ruler, while subtle shifts in tone conveyed the lingering humanity of Momonga beneath the skeletal exterior.
Outside of Overlord, Guerrero is also known for roles in Dragon Ball Super, My Hero Academia, That Time I Got Reincarnated as a Slime, One Piece, and numerous video game projects. (behindthevoiceactors.com)
