During the High Republic Era, the Galactic Republic apprehended and imprisoned a convict from another world, an alien. This extraterrestrial fugitive, along with others, managed to break free from confinement, only to be recaptured by the Jedi Order at a later time.
The role of the alien convict was performed by Liam Cook, who is both an actor and a puppeteer. The voice acting for the character was done by Robin Atkin Downes.
