Kara McGravy was a female botanist exploring the planet Hondran's flora and fauna for Outworld University. She survived two days on the planet amid the mostly carnivorous animal and plant life before the Tenth Doctor arrived. She was also hunted by the Untra. (COMIC: The Hunters / Cliffhanger)
Multi-adventures reference the rare instance when a companion is shown or stated to have multiple adventures with the Doctor but only appears in a single story.
If a medium is not mentioned, then this incarnation did not have companions who were original to that medium; it does not mean that this Doctor failed to appear in that medium.
