A Cyborg Digimon that travels throughout the vast Net Ocean, connecting aquatic Digimon with one another. Amphimon is able to dive into the depths of the sea thanks to the pressurized body suit that covers its entire body. It is even able to enter the Abyss Sanctuary in the deepest part of the sea. Like Angel or Deity Digimon, Amphimon is permitted to judge evil and carry out judgment in the Net Ocean. When a battle breaks out, Amphimon's typically upbeat demeanor can shift as quickly as the tumultuous sea, and it strikes down evildoers with a single blow.
Amphimon fires off frigid energy from its fist to freeze its target with Frozen Crystal, but can swing its hand horizontally to send off a cutter made of highly-pressurized water with Aqua Blade. Thunder Break involves Amphimon delivering an electric kick, literally. With Umbrella Defender, it sets up an electromagnetic shield created by jellyfish units to protect itself and its allies.
