In the manga he had a knife in his mouth during this scene.

Shanny Shan here with another character~

Katsuya Jounouchi also known as Joey (well Katsuya Joey in the short uncut dub).

I'm taking him from early manga (specifically ch 11 & 12 with a twist) or as you can see from these gif, the Toei Anime/Season 0. So he's still rather prone to violence than children's card games.

His mom left him with his father and took his one and only sister with her. While his dad rotted at home drinking all the booze, he had to pay schooling fees by himself by being a paper boy. He used to partake in gang fights, but changed when he met Yuugi. When one of his old gang friends threatens to attack his friends, Jou ends up returning to his gang days briefly to protect his friends. His senses returns when one of the gang members punches Yuugi.

In the end he ends up killing the gang with his branch of sin, impaling them with canine teeth spikes after he was tortured in a warehouse. He was taken in before he could apologize to his friends.

Well, since this is Deadman Wonderland, he'll deny ever having this power. In fact, Jou hates the occult like zombies and mummies Although given his canon, that's very ironic.
