In these episodes, Cyrus explained his belief that the Adamant Orb is Dialga and that the Lustrous Orb is Palkia.
At the end of Unlocking the Red Chain of Events!, Team Galactic was seen taking them to the Spear Pillar, along with the Red Chains. In The Battle Finale of Legend!, 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 control 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.
The Adamant Orb is featured in the Pokémon Trading Card Game as a held item on the Majestic DawnDialga card. This held item works in the same fashion as a Poké-Body, in that the effect the item provides is active whenever the Pokémon is in play.
