Duel Masters Versus Revolution

Benchan, Brainwashed by the Invaders

He provided information to Lulu about Bucchake's whereabouts. At one time, they were attacked by the robot which was programmed by Hakase. After Lulu won, he noticed the Duel Masters Land symbol which rouses his suspicions.

Sneaking into the park, he descends down to the underground city with Hokaben and Lulu after Lulu made an opening. He was surprised on the sights of the city, not expecting this to be on the underground of the park. Finding Bucchake's location, he got into a fist fight with Bucchake until the judge stopped them and asked to settle it in a duel as a better option. However, the duel is also a penalty game in which if a shield breaks, the owner of the shield have to eat spicy ramen. Benchan took off his shirt before the match as the atmosphere is hot and engaged in a duel. He managed to snap Bucchake out of his daze in the match, allowing Bucchake to fight in his full potential. Benchan ultimately won and managed to convince Bucchake to join them again to search for Katta.

However the group was kidnapped by the programmed Gatcha robo and were used as bait for Katta to come out. After Katta's victory in the Duel Zone, he was shot out of the underground city back to the surface.

In episode 14, Benchan was brainwashed by the Duel Masters Land and entered Lulu's card shop right after Katta obtained Iron Fist of Revolution and attempts to use a pair of scissors to destroy the card. He used Cylinder, Revolution Dragon Formula to disable all of katta's creatures and broke all of his shields, but before he can make a direct attack, Katta breaks the seal chains and uses Iron Fist of Revolution to reveal a Machgear, Phoenix Emperor and destroyed his cylinder. Katta then sends out Dogiragon, Flaming Revolution to finish him, knocking him out of his brainwashing, but leaves him unconscious.

When brainwashed, Benchan has an invader mark on his head and has black, shark-like pupils.

When Katta duels Kojiro by the dam, he was able to investigate the cause of Kojiro's strange behavior, which reveals the darker secrets within Duel Masters Land. He then reveals Kojiro's brothers being held captive by the dark society using his laptop, in which they blackmailed Kojiro in order to get Katta out of the competition. Fortunately, Kojiro gave Katta one point, which results in the organization's plans being foiled again.

During the time Lucifer was missing, Benchan entered the secret base and access the database, revealing a secret message about the Forbidden Legend card. He helped Katta in finding the real Duemouse after a few failed attempts. After Katta's loss against Basara, Shobu sent a message to the team about the current situation. Benchan was surprised to hear that the legendary duelists of the past generation, Katta's brother deciding to fight in the upcoming battle. When the group gathered outside to let Shobu and Katta train, he was the only one who noticed Gyou trying to destroy the training area, making him realize Shobu's hidden intentions to the group and suspicions of Gyou. He along with Hamukatsu eventually foiled Gyou's plans.

During Katta's duel against Duemouse in one of the floats, he ominously climbed onto Duemouse's float, mentioning that the remote that Duema Land President was holding deems suspicious, much to the surprise of the group. After the President's failed ploy, the group stays close as a smoke screen surrounds them, which gave the mechanical president a chance to escape. A few days after the park was completely destroyed and Duema Land President true identity as the Kirifuda brothers enemy, Benny Haha was revealed, the group search for any clues in the wreckage of the park and help to evacuate the people that were trapped in the underground city to their freedom.

In order to find out on Benny Haha's location and his plans, Benchan uses one of his test invention to hack into Duemouse's true memory, allowing Duemouse to project it. His experiment was a success, making Duemouse remember everything and made a hasty return. Through the projected memories, Benchan was able to deduce the location of Benny Haha's secret hideout.

He underwent knowledge training with his father until Katta steps in and challenges him in a duel, with his deck and Tech being returned to him.

During the duel, Benchan gave Katta a hard time due to Team Tech's choice abilities. Katta did not back down as Benchan was the one who helped him overcome his initial hatred of dueling rooted from Shobu's 'death' and disappearance.
