Lesthar Darek is an original character created by me around 2010. I made a 3.75 version around that time (You can check the video for the exact date. He was made out of a Kenobi body with Anakin Skywalker arm, and cast head with sculpted hair.

A chiss ( same race as Admiral Thrawn) who was the master tactician at the jedi temple during the clone wars. When order 66 was issued it was natural of him to be one step ahead. He slayed the clones and went into hiding until Vader found him ... It is unclear whether or not he survived the encounter. Thanks for checking!
