The doctor of the neglected Starbase 80, a strange-looking but capable medic who helps deal with an outbreak of apparent possession in the Lower Decks episode Starbase 80?!
Dr. Horseberry is the medical officer of Starbase 80 the run-down station that Starfleet crews treat as a byword for bad luck. He appears in the fifth-season Lower Decks episode Starbase 80?!, when damage to the navigation system forces the Cerritos to put in there for repairs.
Like most of the staff under station commander Kassia Nox, Horseberry looks unpromising, with an appearance that recalls the alien transformations of Tarchannen III. As Cerritos officers begin to shamble about as if possessed, Beckett Mariner assumes the station's reputation as a cursed place is deserved.
The cause is Clem, an anaphasic life form that the Cerritos had picked up earlier and that has been hopping between hosts while trying to make itself understood. Horseberry settles matters in practical fashion, bringing down the dolphin it is occupying with a dip net.
