Plot
The event starts with Giovanni asking Mewtwo to sow seeds of chaos.
At the Pokémon Center, Trista relays news of a strong sync pair causing trouble and warns the player to take caution when exploring the beach.
Brock, Misty, and the player go out to the beach to help stop the trouble. They overhear some Team Break masked men discuss how strong the Trainer is and wonder whether they can make him their boss. However, one of them reveals that he had previously stated not being interested as he was already leader of Team Rainbow Rocket. Brock and Misty interrupt their conversation and Misty realizes that this must mean that Giovanni has come to Pasio. Brock explains to the player that Giovanni is the leader of Team Rocket in Kanto. They decide to stop him but the Team Break thugs try to stop them and start a battle. After being defeated, the masked men leave.
Brock, Misty and the player head into the cave where Giovanni is. After some time, they eventually find him. Misty confronts Giovanni asking what he is up to despite Team Rocket having being disbanded. Giovanni is surprised that Team Rocket is disbanded and guesses he is doomed to be a criminal no matter which world he is in.
Giovanni reveals he was able to mine a sync stone from the cave. He reveals his aim to bend the power of the sync stone to his will and to unleash the hidden power in them. He brings out Mewtwo and battles them to see what the sync stone is capable of.
After the battle, Giovanni sees that it is possible for the bond of a sync pair to manifest great strength. Brock doubts Giovanni will give up on seeking power and believes he was not treating that as a serious battle. Giovanni remarks that the battle was a test run. He dares the player to follow him to for a rematch and then disappears with a snap of his fingers.
The player finally corners Giovanni in a cave. He admits being impressed with the team's full power and asks whether they would like to work with him. Brock does not want to get involved with his evil schemes. Giovanni understands their doubts and states he has been thinking about changing his ways and starting afresh in this new part of the world. Both Brock and Misty are skeptical but Brock suggests that the player could keep an eye on Giovanni by letting him join the team. Giovanni promises not to get involved with Team Break and just to enjoy the PML. As they leave, Giovanni reflects that he has been able to infiltrate their unit successfully and is still deciding whether to truly start afresh or to plan something else.
