Omri Stone works in the Mini Adoption Center. He is a free-to-use NPC.
Little is known about this agent. He dislikes having minis portaled into the Mini Adoption Center with no warning. He didn't seem to be in a very nice mood in his only named appearance, but that may have been due to having had a pack of hungry minis portaled in front of him while he was holding bacon.
He keeps up with who is working with Agent Miah, due to a basically unexplained incident that resulted in seventy or more very angry Pokémon minis being unleashed on the Center. Maniacal laughter may have been involved.
