Trivia

• Adaman was the first character who debuted inPokémon Legends: Arceus to become playable in Pokémon Masters EX.
• Adaman was the first character to become able to be invited to theTrainer Lodge on the same day as their debut in Pokémon Masters EX.
  • This makes Adaman the character with the shortest gap between their debut and obtaining an alternate sync pair, tied withVolo.
• Adaman was the first sync pair exclusively available in a Master Fair scout who can be invited to the Trainer Lodge.
• Upon his release, Adaman had no dialogue when interacting with him in the Trainer Lodge or speaking to him in the Pokémon Center when the game language was set to English or French. This was fixed on June 2, 2023, and all players received 300 non-paidGems as compensation.
• All versions of Adaman use special voice-over lines upon entering a team that contains certain Trainers (regardless of their partner Pokémon) and victory with them. Those Trainers includeIrida,Rei,Akari,Mai,Arezu, andPerrin.
• The moves and passive skills of Adaman (Special Costume) & Ursaluna are likely a reference to the combination of Ursaluna'sAbilityGuts and theheld itemFlame Orb, which is a popular set for Ursaluna in thecore series games.
• InThe Power of Dancecostume event, it is revealed that Adamancaught his Ursaluna in aspace-time distortion.

Moreover,Mai's concept art describes her, Adaman, his Leafeon, anUrsaring, and Mai'sMunchlax as "siblings", consistent with Mai considering Adaman and her Mucnhlax siblings despite being unrelated, and an Ursaring additionally appears inend credits art for theTwo Hues episode ofPokémon: Hisuian Snow. Ursaluna's Dex entry comes from Pokémon Legends: Arceus.

Adaman is not seen owning a Sylveon outside this game. Sylveon's Dex entry comes from Pokémon Ultra Sun.
