"The Power of a Bond! X Tiger"is the 19th episode of Cardfight!! Vanguard G and the 215th of the Cardfight!! Vanguard Anime. This episode marks the re-appearance of Team Caesar from the previous Cardfight!! Vanguard series.
In the film, Kenji, Yuri, and Gai are part of Earth Defense Organization Caesar; they pilot their own giant robots and protect the world from alien monsters. They seemingly destroy one named Zeal, but when they return to the scene, Gai sees that Zeal has shrunk itself and tries to shoot it but catches Yuri in the crossfire. Zeal takes slight control over Yuri's mech and attacks Gai, causing further mistrust. It is then that Zeal appears as an evolved form, attacks the team, and changes into its final form. To retaliate, Team Caesar combines each of their robots into Great Daikaiser. Gai wants to go for the finishing blow quickly, but Yuri tries to stop him for fear of collateral damage to the city. Their infighting causes a misfire that grazes Zeal which escapes. Frustrated, Gai leaves the team.
Later, after discovering that Zeal was what caused Yuri's robot to attack Gai earlier, Zeal appears once more. With Gai gone, Kenji and Yuri attempt to stop it by themselves. They are almost defeated until the timely arrival of Gai. After the team reconciles, they combine into Great Daikaiser again and chase Zeal into outer space, where the team is surrounded and assaulted by a Legion of Zeals. Although heavily damaged, Caesar remains undaunted. Suddenly, the legendary robot Super Cosmic Hero, X-tiger appears before them. With its aid, Team Caesar wipes out the Legion of Zeals, thus saving the Earth. Although Tokoha did not like the movie, Chrono however loved it and becomes ecstatic when he meets the actual Team Caesar at the card shop.
