The older of twin brothers living in Tazmily Village in the Nowhere Islands. In the game, he is shown to be far more courageous than his brother, even going as far as to find and kill the beast that killed his mother. He was found by the Pigmask Army and brainwashed to serve under Porky Minch.
He hunted the Seven Needles, oftentimes crossing swords with his brother, Lucas. In the end, he died, but he is going to make an appearance at Smash Wars regardless.
- Neutral attack: Claus hits his opponents with weak left and right jabs, but will follow up with a deadly spin kick that will cause 10% damage, 3 or 4% if the foe is barely within range. The attack is different when switched to his Masked Man persona. He punches with the arm cannon, which is a weak move.
