Jack Vessalius

Jack Vessalius is the main antagonist of Pandora Hearts. He is the insignator of the Tragedy of Saiber instead of being the Hero of Saiber as previously thought. He is the 'hero' of 100 years ago and the one who 'defeated' Glen Baskerville.

He is voiced by Daisuke Ono who also voices Sebastian Michaelis from Black Butler.
