Also found in Kurumada's original manga, Hell's Watchdog Cerberus (地獄の番犬 ケルベロス, Jigoku no Banken Keruberosu?), the enormous, three headed demonic dog that guards the gates of the Underworld, appears occasionally at its master Hades' side, also serving him as his mount. It is featured more prominently in the anime adaptation, in which it attacks Unicorn Yato, Crane Yuzuriha and Pegasus Tenma during their return from Yomotsu Hirasaka. Defeated twice by Tenma, but temporarily. Although it is depicted in a similar way to creator Kurumada's original design, in Lost Canvas Cerberus' heads are more realistically represented.
