Its revealed that he was a child prodigy who created an application to help people's communication, but he became deeply bitter by seeing people using his creation with bad intentions. In certain episodes, Knight uses a disguise named Cloud to hide his identity, with the disguise he looks more insane and psychotic. After the defeat of the Ultimate 4, Knight is no longer seen.
Knight works for Leviathan and leads the Ultimate 4. At some point in history, he uses Sleepmon to invoke the Leviathan. He has an Appli Drive and is responsible for creating Deusmon by fusing Warudamon and Cometmon (Warudamon refers to him as her "general"). After the defeat of Deusmon and Leviathan, Deusmon regresses to the form of Mienumon and joins the Appli Drivers (along with Knight), being implied that she became his Buddy Appmon.
