During the opening of the Duel Team Carnival, someone hacked the Obots, causing a huge riot. The members of Team ZEXAL found the building where the hacker was and went after him; however, Fusion Mask intercepted them, saying he was the guardian of the first Web Point. He tried to catch Kaito with an arm ring, but Haruto protected him, being caught instead. He explained that the ring would cause strong electric shocks whenever the Duelist suffered damage. Fusion Mask and Kaito then Dueled, with Kaito emerging victorious. Upon Fusion Mask's defeat, Master Evil appears as a hologram, punishing Fusion Mask for failing by triggering his arm ring.
