Hen Jin was a Sith serving man, existing in an era that followed the destruction of the Jedi Order. He pretended to be a Jedi without a master, one of many called to Margrave Juro's Aerial Temple on Hy Izlan, where Juro aimed to give the Jedi lightsabers and bring back the Jedi Order. Juro exposed himself and killed Hen Jin.
The short film "The Ninth Jedi" from Star Wars: Visions in 2021 featured Hen Jin. Daisuke Hirakawa provided his Japanese voice, while Michael Sinterniklaas voiced him in English. The end credits list both Toguro and Hen Jin, though the film itself did not specify who they were. McCarley has since verified Toguro's identity.
