Cerberus.Revolt, known as Dark Cerberus, begins the episode by destroying an entire planet to gain one bone. Victor and Gregory come down to Earth where they return Bear and Grizzly to Morse and Gustos on one condition- they form a line with the two of them that will involve five bones. Victor and Greogory eventually find Shougo and reveal that if Dragon Bone is taken away, Earth will be destroyed because Dragon Bone is the keystone bone for the planet Earth. The group then targets Shougo where the two lines summon the Majin of Thunder and the Majin of Wind, powering up Tiger and Wolf. The move proves to be futile as Jaguar and Leo each manage to fossilize one of Tiger and Wolf's arms, causing the group of five to withdraw. However Liebert begins to think on all the details Shougo has told her and wonders if they should be fighting. Off the planet Cerberus has called together the Council of Elders and discusses the limited success of the invasion of Earth but is countered by Klude pointing out the Majin doesn't wish for meaningless slaughter when one recovers a bone, like Cerberus made occur when he was recovering Griffon Bone. Cerberus is given permission to take over the invasion on Earth, and Luke reveals that Director Higashio is the labs traitor because he is the only one who can remove cards from inside the lab. Meanwhile Higashio has arrived at Shougo's dojo and is talking with Tyrone.
