King Drasil is a host computer being in the form of a tree. Marcus' father Spencer Damon first mentioned him in a flashback during his chat with Merukimon as he was looking for King Drasil. It serves as the main antagonist of the final half of the series when he took Kurata's actions as threat to the Digital World and sends the Royal Knights to attack humanity in retaliation. Drasil initially used the body of Marcus's father Spencer Damon before transferring into his King Drasil 7D6 avatar body, ultimately deciding to destroy both worlds to start anew. But upon being defeated by Marcus and Agumon, Drasil accepts his defeat and enters a deep sleep after reviving Spencer.
