While the Applidrivers were their goal to unlock the door to the Deep Surface, a Reviewmon landed on them, and told them that Cometmon destroyed their home. Haru then used the 7 Code Crowns to unlock and summon Dantemon. Dantemon attacks Cometmon, but Cometmon managed to eat him, but fortunately, Dantemon was still able to destroy Cometmon on the inside, but while he unlocked the door to the Deep Surface, he was turned to stone by Leviathan.
