Bomas were sizable sentient beings, reaching heights of approximately five feet, and their bodies were covered in brown fur. They were not speakers of Basic.
The Rebel Alliance designated a starfighter squadron that engaged the Death Star as "Boma" flight.
Boma are characterized as a hybrid of a brown bear and a guinea pig.
During the initial script of Episode IV, George Lucas' first draft considered Boma as a potential substitute name for Chewbacca. Nevertheless, in the subsequent script, a Boma character named Oeeta resided in the same living space as Han Solo.
"Boma beasts" were featured in the Tales of the Jedi comic series and Star Wars: Knights of the Old Republic II: The Sith Lords as perilous, non-sentient animals on Onderon and its moon Dxun. It remains uncertain if the naming of that species (which bears no resemblance to the sentient Boma) was a tribute to Lucas' draft scripts.
