Neptunmon is a member of the Bagra Army that serves directly under the Head Officer Tactimon (Fusion). He is positioned as the commander of the Island Zone and tasked with finding its Code Crown.

He is formally introduced to Xros Heart shortly after the fall of MadLeomon (Fusion) and attempts to blackmail them to give him the Code Crown by threatening to kill Archelomon (Fusion). Xros Heart fights against him, however, and manages to free Archelomon and defeat his subordinates.

With only Neptunmon himself left, Mikey Kudō uses the DigiXros and forms Shoutmon X4 (Xros Wars) for the first time. Neptunmon throws his weapon at the newly-formed Digimon and it is deflected by the latter´s sword but then it comes back on its own to attack again. Neptunmon then reveals his spear, called King´s Bite, has sentience of its own and will not stop charging until it pierces through the opponent.

Realizing this, Mikey devises a plan with the help of Archelomon to defeat Neptunmon with his own trident. Shoutmon X4 jumps into the ocean with King´s Bite in hot pursuit and emerges grabbing Neptunmon by behind, trying to use the weapon´s own master as a target instead of himself. He grabs his spear and seems to foil the plan. However, King´s Bite increases the power of its attack so much that it throws X4 into the distance and impales its own lord.

As he dies, he attempts a last ditch effort to destroy Xros Heart by summoning a strong and gigantic wave to erase them. They, however, avoid and resist the effects of the technique thanks to the help of KingWhamon (Xros Wars) and claim the Code Crown of Island Zone.
