UPDATE: That may actually be "Tekken" mainstay Yoshimitsu, in a Cardboard Tube Samurai outfit. Seems that pre-orders through various retailers will allow you to access a code to unlock the costume for the samurai robot.
Fighting games seem to be the genre most open to strange cross-overs. A SPARTAN in "Dead or Alive"? Darth Vader in "Soul Calibur"? The latest in a long line of franchise jumpers is probably more niche than you'd expect from a big name like Tekken, but it's guarenteed to bring it a wave of fans.
Yes, that's the Cardboard Tube Samurai, a long-time spin-off character in the universe of Penny Arcade. Even though his head is cast down and his hat covers most of his face, the telltale Pac-Man which adorns his robes makes him pretty much a given.
While the CTS (as he's commonly known) is a perfect fit for "Tekken," I couldn't help but wonder what other characters would've made for good fighting game fodder. The Fruit F***** seems like an obvious choice, but what about Twisp and Catsby as a potentially deadly duo?
