Monster Rancher - Season 2 Episode 22 Blue Skies

Moo is so berserk that he has even started to destroy the Baddie armies. He then travels to Mt. Kyrus to destroy the volcano. The magma, Monol tells them, will cause a chain reaction inside the planet and cause a catastrophic earthquake that will destroy the planet. Monol also says that the Phoenix's soul was split into five subdivisions and fused with five mystery discs. He says that the monsters are Suezo, Mocchi, Tiger, Golem, and Hare. The five fuse into the Phoenix. Both the Phoenix and Moo are destroyed in the battle, and Genki is shunted back to his own time.
