Onodones were a sentient species distinguished by their trunk-like mouths long enough to be draped over their shoulders and looped around. They were rarely seen and often missing from galactic events, obscuring details about this unusual species, their history, and their homeworld, although they perhaps originated in the Unknown Regions.

Gwellis Bagnoro was a mysterious Onodone who was very secretive about his past and an expert forger. Bagnoro spent time at the castle of the pirate Maz Kanata, on the planet Takodana.
