Aqua Admin (Trainer class)/Manga

Pokémon Adventures
In Pokémon Adventures, Aqua Grunts Matt, Shelly, and Amber are promoted to Admin status by Archie in Stick This in Your Craw, Crawdaunt I  after they successfully steal the Devon Goods. They become the 'SSS trio' - "Subleaders of the Sea Scheme." Later, they work together to use energy from Professor Cozmo's meteorite to stop Mt. Chimney's activity, and though Sapphire defeats Matt, their plot is successful. They appear again in Always Keep Whiscash on You for Emergencies when Team Aqua and Team Magma briefly join forces to journey to the bottom of the sea. Archie takes Amber with him, and nearly kills him in Very Vexing Volbeat by locking him and Magma Admin Tabitha inside the Submarine Explorer 1.

During the battle between Kyogre and Groudon, the SSS trio fights against some of the Hoenn Gym Leaders. Matt is ultimately defeated by Winona and Shelly by Flannery. Amber defeats Wattson, but also deliberately allows the Gym Leaders to find the location of the Team Aqua Hideout, suggesting that Archie's treatment of him has caused him to defect from Team Aqua. The fate of Matt and Shelly is not known.

In the, Amber returns to Team Aqua's Headquarters and unexpectedly encounters Blaise. The manga-exclusive counterparts eventually strike a deal to work together, and force to summon  and  using its rings, so that they would be able to trace their respective leaders' whereabouts. It is then revealed that "Matt" and "Shelly" were codenames for the game-based Team Aqua Admins; two new characters which resemble Matt and Shelly in were introduced as co-operators with Zinnia.
