The Strongest Team, Asteroid! known as "Strongest Team, AL4 (Apex Limited Four)!" (最強チーム、AL4 (アペックスリミテッドフォー)!) in the Japanese version is the 30th episode of Cardfight!! Vanguard: Season 1 in the Cardfight!! Vanguard Anime.
Team Q4's final fight in the preliminary rounds, which they cannot afford to lose, begins. Kai takes the stage first, against Asteroid member Yahagi "Crusher" Kyou. Kyou uses a Spike Brothers deck potently. Kai rides Dragonic Overlord and activates its skill, but Kyou blocks it, pushing Kai on the defensive. However, Kai recovers his momentum with a heal trigger, allowing him to reclaim three unflipped damage. He uses Overlord's effect once more, annihilating Kyou's defense and claiming victory. An observing Ren claims the result was not unexpected and grins madly, while Kyou runs off in panic.
