Neptunmon uses Archelomon as ransom for the Code Crown and DigiCards. Before Mikey can give up the items, having heard of the Fusion Fighters' progress from Nene, Christopher arrives on MailBirdramon and takes out some of the Seadramon while offering to deal with the rest in return for the DigiCards. Turning down the offer yet thanking Christopher for taking out some of their opponents, Mikey uses MarineAngemon's DigiCard to summon a bunch of MarineAngemon whose Kahuna Waves subside the Seadramon and Neptunemon.
