Both Pokemon Diamond and Pearl have Team Galactic as the main antagonist team.
Galctic Headquarters is actually the Team Galactic Veilstone Building, but you'll need a Galactic Key to enter most of the doors.
you go to the team galactic ware house
nothing just beat the galactic HQ in Pokemon pearl and diamond
In Diamond you can get Dialga, but you find him in the Spear Pillar after you beat Cyrus of Team Galactic. Im Pokemon pearl you find Palkia.
Pokemon Diamond and Pearl's Team Galactic are ruled by 3 commanders (Mars, Jupiter and Saturn) and the Boss Cyrus.
In the team galactic storage house connected to veilstone galactic headquarters.
