Pluto

Pluto (プルート), also known as Brute, is the King of Daemonium, as well as a Summon Spirit. In most games, Pluto appears as the King of the Underworld.

Tales of Phantasia
Pluto makes his first appearance in the PlayStation remake of Tales of Phantasia as an optional Summon Spirit. Since the PlayStation version, Pluto has appeared in future versions of the game. In the PlayStation and Full Voice Version, he appears in the lowest level of Morlia Mineshaft and requires the "Emerald Ring" to form a pact. In the GameBoy Advanced version of the game, he is instead found in the last level of the Dwarven Temple, requiring the "Lapis Lazuli". Pluto appears as a legless beast with long arms. Pluto challenges the party and, once subdued, he forms a pact.

Pluto battles in the PlayStation version with his pet Cerberus and alone in the GameBoy Advanced version. He surrounds himself with infernal flames to ward away enemies, which he can also fire forward, as well as reach up from the ground with dark hands. He can also cast high-level spells such as Earthquake and Black Hole.
