A 4-episode special web-series that was streamed exclusively on Amazon Prime Video to celebrate the release of the Nintendo Switch game Pokémon Legends: Arceus.

In ages long forgotten, when Earth found itself on a collision course with a meteor, Legendary Pokémon Arceus used its power to avert the danger. However, this feat caused the 16 Plates surrounding it to scatter across the world. Without the Plates providing Arceus with life energy, it began to die. A human named Damon managed to find one of the Plates and returned it to the moribund Pokémon, helping it recover. As a reward, Arceus created the Jewel of Life and gave it to the people of Michina Town, stipulating that it must be returned, but the humans refused, hogging the Jewel to themselves. In the battle that ensued, Damon was killed and Arceus went into slumber, vowing to punish humanity upon its return. Satoshi and his companions arrive in Michina Town where they come across Sheena, a descendant of Damon, who claims to be in possession of the Jewel of Life and intends on giving it back to Arceus when it awakens. The situation takes an unexpected turn when Arceus, despite Sheena's best intentions, remains unsatisfied. Satoshi must now prevent the destruction of the entire human race, as Arceus' fury causes distortions in the fabric of the universe, enraging the Legendary trio—Dialga, Palkia, and Giratina—and disturbing the world's balance.

Using the fossil of the Legendary Pokémon Mew, Team Rocket has created the first successful Pokémon clone. Named Mewtwo, the man-made Pokémon quickly becomes upset with the circumstances of its creation and goes on a rampage. It is soon approached by Sakaki, the leader of Team Rocket, and is manipulated into committing evil acts. Repulsed by the tricks of mankind and the cruelties it has suffered, Mewtwo isolates itself from everyone and plots against humans whilst trying to discover its true purpose in life. Disguising as the world's strongest Pokémon trainer, Mewtwo draws in the region's most powerful trainers who want to fight the new, mysterious opponent. With the fate of the world at stake, renowned trainers Satoshi, Takeshi, and Kasumi must battle against Mewtwo and defeat it before it brings about the downfall of humanity.
