Just as the core was knocked out of the pentagram, the room started to shake like an earthquake. The middle where where the core was had the ceiling come crashing down which Joey dodged out of the way as did Tristen, each monster came to their respective summoner to aid them. Mana had appeared before Yugi to shield him from the dust and debris. Mahad took to defending Duke and Yami where as Joey's Gearfried helped Tristen, and Red eyes helped Joey. 

From the rubble was a massive beast. Once the rubble had cleared there stood Exodia, Master of the Guard as well as several other monster spirits. 

Joey looked to the monsters that were now in the room with them to see they now were going to have a fight on their hands.
