Great Pokemon War

The Great Pokémon War was started shortly after Garvadon angered Arceus when attempting to capture the legendary Rayquaza. The war also occurred as a result of Garvadon revealing information to the five tribes about the sacred Jirachi and its ability to grant wishes. Although Garvadon had no interest in this Pokémon, he knew that telling the tribes about it would surly cause a competition to capture this mythical being. Garvadon had a goal of capturing Rayquaza and Giratina, both of which, as he soon discovered, would only be possible if a major catastrophe was to occur. By starting the war, Rayquaza would be guaranteed to flee from the sky to stop Garvadon in his tracks, ultimately resulting in its capture as Garvadon caught the unaware Rayquaza. Shortly after, as punishment for capturing a true legendary and starting the war, Arceus came down and banished Garvadon to the Distortion World, where he would later meet Giratina.

The Battle

After the tribes heard about the great Pokémon Jirachi, countless trainers sought to capture it for their own. The tribe leaders forbade the idea of capturing the Pokémon, as it was sure to bring great chaos if it falls into the wrong hands. Rebellious members betrayed or left their tribes and even attacked their own members' Pokémon and even killing the members themselves.
