DigmonEdit

Digmon, the "Drill of Power"and "Drill of Knowledge" is the form Armadillomon takes when he Armor Digivolves with the Digi-Egg of Knowledge. He noted that the "drill of knowledge" makes him sound smarter.

Armadillomon first Armor Digivolved to Digmon on the day of his revival,^[3] when the Digimon Emperor abducted Davis. Cody's desire to understand life's mysteries evoked the power of the Digi-Egg, allowing Armadillomon to Armor Digivolve to Digmon and destroy the Dark Ring on Drimogemon, a Digimon who was under the Emperor's control. Digmon was a valuable fighter during the Digimon Emperor's reign of terror, but when Ken renounced his evil persona, Digmon was no longer needed as Armadillomon was now able to Digivolve normally.

Submarimon, the "Reliable Guardian of the Seas", is the form Armadillomon takes when he Armor Digivolves with the Digi-Egg of Reliability.

Armadillomon first became Submarimon on the day the Digi-Egg of Reliability was found. The DigiDestined children had been trapped in an offshore oil platform by a MegaSeadramon who was under the control of the Digimon Emperor. Cody was able to invoke the power of the Digi-Egg of Reliability, allowing Armadillomon to Armor Digivolve to Submarimon. With the help of Ikkakumon, Submarimon destroyed the Dark Spiral on MegaSeadramon and freed the DigiDestined. Submarimon is one of the few digimon forms belonging to the Digimon who is well-equipped for combat in water, even able to attack Ultimates head-on. Submarimon's head also contains a cockpit that can fit a single human, meaning he can be used as underwater transport or to help destroy the Control Spires.

AnkylomonEdit

Ankylomon is Armadillomon's champion form. His name is derived from the dinosaur ankylosaurus.

Armadillomon first digivolved to Ankylomon to protect Cody from Thundermon, who the DigiDestined encountered when they were helping to rebuild the Digital World after all the damage done by the Digimon Emperor. Since then, Ankylomon has appeared more than Digmon and Submarimon. Later, during the DigiDestined's final battle against BlackWarGreymon, Ankylomon was able to DNA Digivolve with Angemon to Shakkoumon, who was the first to actually inflict any real damage on the Mega-leveled BlackWarGreymon. He was also vital to battle against the Daemon Corps and MaloMyotismon.

When the Old Clock Shop Man summons the heroes of the past to the Fusion universe to help take down Quartzmon, Ankylomon shows up with Cody Hida and MagnaGarurumon to assist in the DigiQuartz. A Great Legendary Hero Gathering! The Digimon All-star Showdown!!

ShakkoumonEdit

Shakkoumon is an Ultimate-level Mutant Digimon DNA-digivolved from Angemon and Ankylomon, combining Ankylomon's armor with Angemon's holy power. Shakkoumon was first formed when the DigiDestined attempted to protect the last Destiny Stone from BlackWarGreymon. Both Cody and T.K. knew that the Destiny Stone must not be destroyed, regardless of BlackWarGreymon's wishes, so their partners, Angemon and Ankylomon, were able to DNA digivolve and form Shakkoumon, who teamed up with Paildramon and Silphymon to fend off BlackWarGreymon. Although the three Ultimates were unable to defeat BlackWarGreymon, they were able to stall him for long enough for the children to evacuate the Destiny Stone and get it to safety.

When he runs out of energy, Shakkoumon degenerates to Tokomon and Tsubumon.

Shakkoumon is Armadillomon's Ultimate form through DNA Digivolution in Digimon Tamers: Digimon Medley and his natural Ultimate form in Digimon Tamers: Brave Tamer, though by equipping him and Angemon with Calumon cards they can digivolve to Shakkoumon.
