Guardians

The three Guardians are three powerful Digimon who appear in the video game Digimon World 2. Each Guardian represents one of the Digimon types (Vaccine, Virus, Data), and so they are the Vaccine Guardian, the Virus Guardian, and the Data Guardian. They are the Grand Beings who created Tamers, by teaching them their Tamer Techniques and how to digivolve Digimon. They offered those things to the humans in the Digital World in exchange for a promise, which was to show the strongest Tamer (when they found him) the path to a new world, the Kernel Zone, where the Guardians are. Akira, the protagonist of the game, proves himself to be that Tamer after completing many difficult missions, and is sent to the Kernel Zone. There, he goes to Core Tower, where on the 24th and last level he meets one of the Guardians, whose type is the same as the one of the Guard Team he is a member of (so, if Akira joined the Black Sword which specializes in Virus Digimon, he will meet the Virus Guardian). The Guardians are extremely powerful (compared to the wild Digimon), having 999 HP, even more than the final boss of the game, Overlord GAIA. Akira battles the Guardian who, after being defeated, shows Akira the way to Overlord GAIA.
