Hazeport Residential Towers are a composite of special buildings that are scattered around Hazeport City. Each building in this system is adorned with gemstone-inspired colors and within each building, resides trainers that their Pokémon-type specialization, appearances, or possibly names aligned with the gem's color.
The system exclusively serves as a place for players to battle against trainers and have no other purposes. It can be accessed after the player completed the final mission.
