Evan, hailing from the planet Garqi, was a youthful farmboy of the Human species.
During a clash between the Galactic Republic and Separatist armies, Evan's parents tragically perished. This loss orphaned Evan, forcing him into seclusion until he was found by the clone commandos belonging to Aiwha Squad. While journeying with Aiwha Squad, Sarge received Order 66, and Evan was a horrified witness as the squad executed Jedi Master Traavis.
Initially hesitant to depart his home with the clone commandos, Evan eventually grew fond of them. Despite his initial fear when facing a homing spider droid, he later described the experience as "awesome". He held a strong fascination with the Jedi Order and was deeply disturbed by the implications of Order 66.
Ryan Kaufman conceived Evan for the short story Orders, which appeared in the fourth volume of the Star Wars: Clone Wars Adventures trade paperbacks series. Rick Lacy provided the artwork for the character. Evan was also included in The Complete Star Wars Encyclopedia.
