Hacker

A hacker (ハッカー, Hakkā) is someone with the ability to force an item, program, or system to deviate from its intended programming to satisfy their own desires.

A malicious hacker once managed to disrupt the Computer Network, and it was still being repaired when Coelamon was discovered, while the evil feelings of hackers who abuse the Network produced Devidramon. Octmon was discovered from the virus that a fiendish hacker used to crash a rival's research computer. Although the Firewall prevents illegal entries from hackers, the very defenders of the Network are subject to being taken advantage of themselves as was the case with Guardromon, who was originally a Digimon that worked alongside Giromon in repelling those who try to illegally enter the Network until a malicious hacker infected it with a computer virus and was subsequently used by that hacker as means of protection from the Virus Busters. Tekkamon is said to have been created by an evil hacker to destroy programs in response to Giromon.

The Kuremi Detective Agency took a job related to their clients' accounts being stolen in a low floor of Cyberspace EDEN, which Aiba Takumi recognized as a case of account hacking. After breaking through a firewall in Coulomb, Takumi was dragged into a portal that appeared from behind it, which shifted them to another space. Said space was a secret base of the hacker group Demons, where Takumi found a lot of data of stolen accounts, and was attacked by a Growmon controlled by them. The Hackers decided to take his account and Digimon. Takumi asked them why they stole accounts. The spiky-haired Hacker answered him, saying they could use the stolen accounts to disguise themselves and do criminal acts without repercussions, how the Cyberspace existed for them, and how, with an enormous amount of accounts and Digimon, they could control the Cyberspace and, eventually, the Real World as well. They were unable to steal Takumi's account with their Cyclomon as his body was half-digitized. A battle then happened between both sides, which Takumi won, however, before Takumi could take them to justice, an Eater (Purebreed Mode) appeared from behind them and absorbed them, leaving Takumi in a state of shock.

Analogman is a hacker that serves as the final boss of the game. He wants to take over the Digital World and sees Digimon as nothing but tools, however, he's ultimately beaten by the Player and his attempt at leaving File Island fails, causing him to disappear, screaming for help.

Analogman, only referred to as "A", returns by hacking into the Digital World of Digital Card Arena, taking over Infinity Tower's Venom Vamdemon's body, forcing the world to switch to Safety Mode. He wishes to take over the world, and according to him, it is only a matter of time before he does and he has infinite time. "A" cheats when fought, hacking into the world so his deck won't be shuffled and the Player's Partner Cards are sent to the bottom of his deck. Nonetheless, he's once again defeated and loses his access. He tries hacking his way back in, only to fail, entering an infinite loop. Rosemon, the security program, then speaks, saying that she has put his current directory in her Domain, so he cannot escape anymore, and can only repeat endless math equations. "A" threatens to destroy Rosemon, but Rosemon anticipated it and cuts both herself and "A" off the world and into the space of the Net. This causes "A" to panic, as he does not want to go back there, and he begs her to stop, which proves futile.
