Arkadimon (Cyber Sleuth)

Arkadimon is the one of the main antagonists. It is a Digimon who was imprisoned on Underzero, then escaped and caused havoc in the Real World and EDEN as one of Mishima Ryuji's partner Digimon.

Whilst in Under Zero, Mishima Ryuji accidentally frees Arkadimon (Baby), who attempts to kill Ryuji. Cyberdramon takes the blow instead, saving Ryuji. Soon after absorbing Cyberdramon, Arkadimon evolves into its Child form. On Kowloon Lv.1, Ryuji orders it to attack Takkun and Mipori.

When Amazawa Keisuke is about to lose to K and his Skull Satamon, Ryuji and Arkadimon (Child) easily defeats and absorbs it. They then go on a rampage, absorbing all sorts of Digimon all over EDEN and the real world, in an attempt to eliminate all hackers in the world as revenge for an Eater eating Imai Chitose. After absorbing an Ice Devimon it evolves into its Adult form. Keisuke arrives to confront Ryuji but he just walks off.

Fei Wong Tomoe Ignacio, Makiko Date, Keisuke and Mishima Erika come up with a plan to ambush Ryuji, in which they stall him in EDEN and then catch his body in real life whilst he's logged in after Erika hacks to find his position. Fei stalls Arkadimon whilst Keisuke and Date track down Ryuji in the real world, however it appears Ryuji was one step ahead of them and the signal sends them to a random hacker instead. When Fei is informed, the Ryuji/Arkadimon in front of them vanishes, with it merely being a fake. Upon returning to the Hudie base, Ryuji walks in and states that Fei is first on his list to kill, as she was responsible for Chitose being attacked by an Eater, as it was Zaxon's plan to go to Under Zero and that after he's killed Fei, Kamishiro Yuugo was next. Fei is pissed off at the threat to Yuugo's life and her Cyber Sleuth comes out to help Fei. Erika attempts to calm down her brother but Ryuji just screams at her, saying that him losing all his friends, his family and even Erika herself is her fault. Arkadimon then evolves into its Perfect form, destroys the Hudie base, and flies out into the sky, with Keisuke - who was on his way back - seeing the duo flying off. Tiger Vespamon manages to save the lives of Fei and Erika whilst the building collapses.

Keisuke eventually finds Ryuji and Arkadimon (Perfect) in Akihabara. Keisuke tells Ryuji that Chitose is now awake, as he and Erika had hacked an Eater, gone to the Eater World and acquired Chitose's data, allowing them to restore him out of his Eden Syndrome. Ryuji doesn't believe Keisuke and Wormmon and then states the two had betrayed him and attack the duo. After Keisuke manages to defeat Arkadimon, Ryuji flees to find more Digimon to have his Arkadimon eat to power back up. At this point, Sanada Arata in his Eater forms arrives and the three team up, searching the Akihabara Digital Shift. They find Ryuji has caused it to be an endless loop, so hack the environment and find that three random hackers have been mind controlled to cause it. After defeating them in a Domination Battle, the area is restored to normal and the three find Ryuji with Arkadimon eating multiple Digimon to power back up. Ryuji then sees Arata and states that Keisuke has betrayed him after all, since he is now teaming with the guy who betrayed Ryuji by leaving Jude. Ryuji and Arata argue over it and when Arata states that it's Ryuji's fault Jude ended because he could've just continued without Arata there, Ryuji's anger causes Arkadimon to evolve into its Ultimate level. Keisuke and Arata manage to defeat Arkadimon, leading Arata to reveal he left Jude because in the past he got friends killed and losing in Under Zero brought those memories back. He didn't want to lead any other friends into getting killed again and that he knew Ryuji would force him to be the leader again and that Ryuji would've been a good leader for Jude, due to how well he had been leading Hudie until he and Arkadimon started murdering hackers. Arata then leaves, with Ryuji in shock. Suddenly, Chitose and Matayoshi Gorou arrive with Ryuji being amazed that Chitose is awake like Keisuke had claimed. The dark aura suddenly vanishes from around Ryuji as he's happy to see his best friend alive. Just as Ryuji states he's done too much to ever return to Hudie though, Chitose is pissed and throws Wormmon at Ryuji, screaming at him about how Ryuji has been an idiot in his actions and that attacking Zaxon pretty much screws over Hudie. After getting everything out, Chitose asks for Ryuji to return though before he can, Arkadimon wakes up and attempts to murder Chitose. Ryuji dives in the way, protecting him in the same way Chitose had done before, leaving Ryuji to take the blow and get absorbed by Arkadimon, who then flies off with Keisuke, Chitose, Wormmon and Matayoshi shocked. Ryuji is able to talk to Arkadimon whilst inside him with Arkadimon stating that he will destroy Ryuji before anyone else can and before his friends abandon him for what he has done. Ryuji apologises for making his partner the way he is, though Arkadimon still tries to kill Ryuji. Cyberdramon suddenly appears and blocks the attack, with Ryuji happy to see his old partner survive. They then decide they need to return to Hudie.

After having absorbed Ryuji, Arkadimon is shown appearing from inside a lake in Odaiba in its Super Ultimate form. Keisuke and Erika arrive to try and fight it but find their Digimon unable to hurt the building sized monster. With no way to win, Wormmon wants to flee, only for Erika to send her Eater Bits to attack it instead. This slows down Arkadimon, with Keisuke's Digimon now able to hurt the giant Digimon. They manage to defeat it after a long fought battle. After being defeated, Arkadimon explodes with Ryuji and Cyberdamon being released in the air. Cyberdramon flies Ryuji down to the bridge, with Makiko Date charging in to arrest him, though changing her mind when seeing him injured, instead getting him am ambulance. Erika then collapses due to overexerting herself, which leads to her Eater Bits attacking her, merging with her body to create Eater Legion and then flying off, with everyone shocked at what just happened.
