Here we go, then: Neo LeChuck:
To editorialize: I like it! Boen-esque yet with an individual spin. Suitable to the character. Very LeChuck. As for the blah-ing: If I were a betting man, I wouldn′t be surprised if, in the final game, the VO would fade into the background as we regain control of the game.
And that LeChuck′s Revenge-style music. Chef′s kisses all around.
Update! Sources have confirmed to Mojo that LeChuck is voiced by the prolific Jess Harnell. (The source being a Tweet from Ronzo.)
