Rengar

"Bathoz, Jillian, Rengar... If this is some sort of joke it isn't funny. Come on...pick up..."

- Lisum transmitting through a radio

Rengar was a male researcher who lived during the time of the Galactic Civil War. Sometime following the Battle of Yavin in 0 BBY, Rengar and two other colleagues, Jillian and Bathoz, were kidnapped and killed by the Canopy Bandits on the planet Kashyyyk. Enraged, a surviving colleague named Lisum asked a spacer to kill the Canopy Bandits out of vengeance.

Behind the scenes
Rengar was first mentioned in 2005 expansion pack Rage of the Wookiees for the massively multiplayer online-role playing game Star Wars Galaxies: An Empire Divided, prior to its closure on December 15, 2011.

In the video game, the name Rengar was mentioned in the quest dialogue along with the names of two other colleagues. When the player was tasked with investigating the Canopy Bandits' camp, they would discover the dead bodies of two of the three researchers, a Human man and woman. The woman was clearly implied to be Jillian, however it is unknown if the man was Rengar, or the other male colleague named Bathoz. Therefore, while Rengar was implied to be a male in the quest dialogue, it cannot be said with absolute certainty if he was the dead Human seen in the game. This make his species ambiguous.
