Bandril

Apparently reptilian, the Bandrils lived on a planet near Karfel. The Bandrils' relationship with the Karfelons was sometimes friendly. The Bandrils subsisted in part on grain from Karfel. (TV: Timelash)

The Bandrils tried to invade Earth before 1997. UNIT fought them off without the Doctor's assistance. (PROSE: The Dying Days)

The Eighth Doctor and Charley Pollard once visited a Bandril spaceship. (AUDIO: Time Works)

Bernice Summerfield learned of a potential dig site on Javarda from a Bandril trader. (WC: Dead and Buried)

Behind the scenes
Lance Parkin has stated that the Bandril invasion reference was a joke, based on the Bandrils being "rubbish" monsters, and that "some alien invasions were beneath the Doctor’s dignity to deal with".
