Toz is the three-armed Edosian who welcomes the overworked engineers of the USS Cerritos to the Dove, a relaxation facility, and tries with little success to make them rest.
Toz appears in Room for Growth, in the third season of Star Trek: Lower Decks. After the Cerritos engineering team wear themselves out putting the ship right, Captain Freeman orders them to the Dove for compulsory rest.
Toz fits each visitor with a wristband that changes colour with their stress level and steers them towards massages, music and other calming pursuits. The engineers, led by Andy Billups, cannot stop thinking about work and keep slipping away to tinker.
When Rutherford and his colleagues build a pod that removes stress in an instant, Toz has it thrown out into space, since such a device would put her out of a job. She is voiced by Mary Holland.
