Yusei puts up a good defense, but finds himself pressured. After hanging on for a while, Yusei remembers that he has a second chance, and uses Speed World 2's effect the Crimson Dragon's power to draw another card during his draw phase, which grants him the tuner monster Majestic Dragon, and he is able to retrieve Stardust Dragon using the trap card Syncro particle, and summons the Majestic Star Dragon, and then attacks Wisel Top, resulting in the destruction of the rest of the Machine Emperor, defeating The Ghost. The Ghost then crashes into a forest, and one of the 3 emperors of Yliaster, Primo, retrieves Ghost's duel disk, and his own Wisel deck from The Ghost's duel runner. When Yusei, Jack and Crow arrive at The Ghost's crash site, they discover he is actually a robot that Trudge identifies as a Duel-Bot, that was stolen from Sector Security, and reprogrammed.
