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. Using Syakomon and her kin as a bridge, 
Shoutmon ×2 carries Mikey and Jeremy toward Neptunmon with the latter 
using the Rare Star Sword to free Archelomon. Neptunmon then knocks them
 into the water and has the Seadramon freeze the ocean surface to trap 
them! Luckily, as the fight was disrupting his fishing, Dorulumon 
arrives to free the Fusion Fighters and Archelomon. Mikey then DigiFuses
 Shoutmon, Ballistamon and Dorulumon with the Star Sword into Shoutmon 
×4. Shoutmon ×4 ends up fighting against Neptunmon's sentient King's 
Bite spear, ultimately using Neptunmon as a shield against his own 
weapon. Though a dying Neptunmon makes one final attempt to kill 
everyone, KingWhamon saves the Fusion Fighters. Tactimon is infuriated 
by the turn of events. Soon after, as Christopher departs to let them 
make his job of harvesting more Code Crowns easier for him, 
ChibiTortomon officially joins the Fusion Fighters while Mikey is unable
 to convince Dorulumon to join their group.
