Armadimon, also known as Armadillomon, partners with Cody Hida (Iori Hida). This Mammal-type Digimon sports a hard, armadillo-like shell and maintains a consistently cheerful, optimistic personality. Its demeanor contrasts sharply with Cody's serious, rule-oriented nature, yet Armadimon embraces and complements his partner's traits, often injecting lightheartedness during their downtime. The Digimon speaks distinctively, using a Nagoya dialect in Japanese portrayals and occasionally demonstrating rapping skills. Originating from an ancient Digimon lineage shared with Veemon, Armadimon was sealed by the Digimon Sovereign Azulongmon for future crises. It awakened during the Digimon Emperor's conquest of the Digital World. Cody freed Armadimon from suspended animation by lifting the Digi-Egg of Knowledge on his first journey to that realm. Armadimon's evolutionary line includes Tsubumon (Fresh) and Upamon (In-Training). As a Rookie, it undergoes Armor Digivolution: with the Digi-Egg of Knowledge, it becomes Digmon (Drill of Knowledge), excelling in subterranean combat; with the Digi-Egg of Reliability, it becomes Submarimon (Reliable Guardian of the Seas), adept in aquatic environments; and with the Digi-Egg of Love, it becomes Pteramon. Its standard Champion form is Ankylomon, a dinosaur-like Digimon. Through DNA Digivolution with Angemon, Ankylomon reaches the Ultimate-level Shakkoumon, a Mutant Digimon fusing defensive armor and holy power. Vikemon serves as its Mega form in select media. In *Digimon Adventure 02: The Beginning*, Armadimon accompanies Cody during his pre-law studies and part-time work at a law firm, balancing Cody's disciplined lifestyle. During the climax, Armadimon battles the giant Digimon BigUkkomon. After digivolving to Ankylomon and DNA-digivolving with Angemon into Shakkoumon, it severs most of BigUkkomon's tentacles alongside Silphymon, enabling Imperialdramon Fighter Mode's decisive strike. Post-battle, Digivices disintegrate globally, signifying that human-Digimon bonds endure without physical devices. By 2027, Armadimon remains Cody's partner. Cody becomes a defense attorney with a family, fathering a daughter. Armadimon accompanies him to his law firm and questions Cody's career choice, prompting Cody to explain his belief in redemption, shaped by experiences with Ken Ichijouji and Yukio Oikawa. Armadimon later joins Cody and his daughter at a Digital World gathering with the original Chosen Children and their Digimon partners.
