Max (マックス Makkusu) is one of the four, and seeming leader of, the Neon Genesis Junior High Students that act as support units for Gridman. He transforms into the Assist Weapon Battle Tracto Max (バトルトラクトマックス Batoru Torakuto Makkusu).
Despite his imposing appearance, Max is actually a gentle person. He also shown to be supportive of Yuta's feelings towards Rikka while finding it vexing. He also has shown more leadership qualities and responsibility than the other members of his team.
Max showed up with the remaining two Junior High students after Anti had defeated Gridman and Calibur. The trio invited themselves into the Junk shop, already aware Gridman was alive. During the rematch, Max transformed into Battle Tracto Max and backed the Hyper Agent up. The two fused into Max Gridman and fought Anti to a stalemate. He and the other Assist Weapons continue to fight alongside Gridman and Yuta. He also notices that all the kaiju are appearing around Yuta and his friends. While following Yuta around, he saw Anosillus the 2nd's interactions with the boy and defended Yuta when Anti attacked him.
To awaken Gridman's true form, the Neon Genesis Junior High Students gained Acceptors and were integrated back into Gridman for the final battle. After that was over, he departed with Gridman back to the Hyper World.
