Kieran, a character in the Indigo Disk Dlc of Pokémon Scarlet and Violet, is officially the strongest trainer in the series, surpassing Cynthia's average team level. Kieran's average team level is slightly higher than Cynthia's in Brilliant Diamond and Shining Pearl. Despite Kieran's higher average level, Cynthia still holds the title of Pokémon League Champion, one thing Kieran hasn't achieved (yet).

An unassuming character featured in Pokémon Scarlet and Violet's Indigo Disk Dlc is officially the strongest trainer ever to appear in the series. Indigo Disk is the second part of Scarlet and Violet's expansion, The Hidden Treasure of Area Zero. Following The Teal Mask, it has players visiting Blueberry Academy as an exchange student, where they'll battle a variety of trainers from all around the world. There's also a wide variety of new Pokémon to catch in Indigo Disk, along with new regions to explore and new mysteries to uncover.
