The Adamant Orb appeared again in Losing Its Lustrous!, where Team Galactic attacked a police plane transporting the Adamant Orb from Eterna City to Celestic Town and stole it. In the next episode, Double Team Turnover!, after both orbs had been stolen by Team Galactic, the Lustrous and Adamant Orbs were shown being connected to some kind of machinery at the Team Galactic HQ.
In these episodes, Cyrus explained his belief that the Adamant Orb is Dialga and that the Lustrous Orb is Palkia.
The two orbs made a brief appearance at the end of Unlocking the Red Chain of Events!, where Team Galactic was seen taking them to the Spear Pillar, along with the Red Chains. The orbs reappeared in The Battle Finale of Legend!, where Cyrus placed them and the lake guardians in place around the ruins at the Spear Pillar. This process allowed him to call forth Dialga and Palkia, who were immediately taken under his contol by the Red Chains. After Cyrus's attempt to create a new world had been foiled and Team Galactic had been defeated, Gary secured the orbs and decided to return them to Professor Carolina.
