From Bulbapedia, the community-driven Pokémon encyclopedia.
Crimson (Japanese: チシヲ Chishio) is a character of the day who appeared in Beating the Bustle and Hustle!. She is part of a criminal duo with Azure.
Crimson and Azure both became contestants on the television program Sinnoh Pokémon Hustle, which was fabricated by Team Rocket with the hopes of stealing Pokémon. Officer Jenny had been tracking the two for quite some time and disguised herself in order to follow them.
Crimson had entered with her Zangoose and showed off her acrobatic skills as she and Azure were some of the few people able to beat the challenges in the game show. She and Azure eventually came across the box that Team Rocket had been keeping all of the Poké Balls that they took from the other contestants, and decided to help themselves to it. Team Rocket mistook Crimson and Azure as members of their organization sent by Giovanni, and helped them escape from Officer Jenny.
Crimson and Azure eventually revealed that they were not members of Team Rocket. A battle then ensued between the two criminal teams. Crimson used her Zangoose in a Tag Battle with Azure and his Drowzee. Both easily defeated Meowth and Jessie's Yanmega, but eventually fell to Officer Jenny's Growlithe. Both Crimson and Azure were then arrested by Officer Jenny and taken to jail.
