Once again, the kids and the Digimon fight Tyranterramon, this time with the help of a reborn Five Regions' Guardian, who is not as de-powered as Jiji and Baba. This book is only about half over, so they don't beat him yet. They do gain new allies, though, and this chapter sets up an important detail for the climax of the book: the existence and nature of Legacy Codes, which are fractal codes (like the ones introduced in Digimon Frontier) which contain the lingering powers and memories of a Digimon who is about to reconfigure and wants to preserve something of who they are. When the characters refer to the power to control fire given from Phoenixmon to SkullMeramon, they are discussing the transfer of Phoenixmon's Legacy Code to SkullMeramon.
