Digimon 02
Armadillomon first became Submarimon on the day the Digi-Egg of Reliabilty was found, when the Digidestined were trapped in an offshore oil platform by MegaSeadramon under the control of the Dark Spiral and had to send Cody Hida to get help. When Cody got back, his understanding of how his lie saved lives evoked the Digi-Egg's power, allowing Armadillomon to Armor Digivolve to Submarimon, who destroyed the Dark Spiral on MegaSeadramon. Since then, Submarimon was a valuable fighter during the Digimon Emperor's reign of terror. But once Ken renounced his evil persona, Submarimon was no longer needed & appeared only a few times as Ankylomon was used more. But during the battle with MaloMyotismon, Submarimon was manifested as a result of Cody's dream for justice. Submarimon is also used for underwater battle and transport.
