Bootmon is considered "the most important person" by Leviathan, who wants to find him. A picture of him is kept in a secret file in the Deep Web.
When looking for Hajime, Rei Katsura and Hackmon steal files on people related to Leviathan, and finds Bootmon's picture, with the name partially obscured. On the same day, Leviathan orders the Ultimate 4 to look for him. When escaping from Leviathan,
Rei and Hackmon stumble upon an image of Bootmon with his name intact. On the same day, Knight Unryuji asks Eri Karan to help him find Bootmon. It is later revealed that Hajime actually created Bootmon under Leviathan's orders, and sent him off into hiding the minute Biomon showed up. He is then followed by the Appli-Drivers, only to be found by Haru, Gatchmon, Yujin, and Offmon. However, Yujin later appliarised Shutmon and forced him to reduce Bootmon down to a chip, later revealing himself to be an android created by Leviathan to infiltrate the Appli-Drivers, and further initiate the Human Applification Project by capturing him.
Bootmon is Hajime Katsura's Buddy Appmon. His app was created by Hajime.
