Benny Haha

Benny Haha, (邪藩 牛次郎; Japan Gyūjirō) also known as Gyujiroh Japan, is the third of the four Temple Guardians, as well as being Mimi's "twin brother" in the English dub of the anime (In the Japanese, this is not shown).

Season 1
He is often seen piloting a robot. In his Temple duel against Shobu, he unfairly used cameras installed in various statues to look at Shobu's hand as well as using the information to scare him and gain an unfair advantage.

Duel Masters Charge
He returns in Season 2 as Gyujiro Japan and he defeated Jamira in the Duel Masters Battle Arena Tournament finals, but he is still evil. He tricked Hakuoh before their official match by kidnapping Mikuni and Makoto Aizen. Afterwards when he was not able to defeat Hakuoh in a duel, he injured Hakuoh so he would not be unable to duel him the next morning in the Finals. He ended up dueling Shobu again, but lost.

He is also working with Yumama. After he lost to Shobu, Yumama trapped him in a room with Boy George. They both escaped inside The Battle Arena by digging themselves out and claimed to the crowd that she have been defeating the other contestants before the official duel just so that she can duel Shobu.
