Pokémon crime organizations
In Diamond and Pearl, they kidnap the legendary Lake Trio (Uxie, Mesprit, and Azelf) and take crystals from them to create an item known as the Red Chain, which chains and controls a Pokémon, yet keeps their full power. The player goes in Galactic's headquarters and defeats Cyrus, so he lets the player release the three after beating Saturn. At the Spear Pillar, Cyrus uses the Red Chain to bring the legendary Pokémon Dialga (in Diamond) or Palkia (in Pearl) out, planning to use their power to create the new universe, over which he will be the new leader. However, the Lake Trio come back to suppress the legendary's power and break the Red Chain, stopping Cyrus. After this, and Cyrus's failure to defeat the player, most of Team Galactic leaves including Cyrus himself. Only a handful remain in Veilstone City, led by Saturn, who has decided to found a new, better Team Galactic.
