Astamon is a Demon Man Digimon whose name and design are derived from the mythological Astaroth. Though it is an Ultimate Digimon, it possesses power surpassing that of a Mega, and is a Prince of the Dark Area which governs a legion of Demon Digimon. It shows cruelty to its enemies and kindness to its friends, and because of that charisma it is expected to gain a considerable number of followers among Demon Digimon. Its prided machine gun, "Oro Salmón" (Esp: Gold Salmon), is the work of Vulcanusmon, who crafted Beelzemon's favorite guns, the "Berenjena" (Esp: Eggplant), and the bullets fired from it possess their own will, so they will definitely chase the opponent to the "end of hell".
- Hellfire: Fires every last bullet from the Oro Salmón.
- Maverick: Attacks with a kick which unleashes all of its pent-up dark Qi.
