CT-21/0408 "Echo" is one of my favorite characters from the Clone Wars animated series. "Echo" got his nickname due to his constant "echoing" standard clone rules and procedures. During his time at the Rishi Outpost Station, he enjoyed the quiet and spent his time reading the reg manuals.
The station would later be attacked by elite commando droids, and the "rookie" clone trooper was pushed into action. After a skirmish with a Rishi eel, Clone Captain Rex put his hand (covered with the eel's blood) on Echo's chest armor, as a symbol of his "graduation" from "rookie".
After the incident, Echo and his surviving team mate "Fives" would serve in the battle of Kamino, where he and Fives would prove themselves again. After the hard fought battle, Echo and Fives were promoted to ARC Troopers for their heroism and valor.
Echo and Fives assisted in the rescue of Jedi Master Even Piell from the maximum security prison called "The Citadel", and Echo lost his life in a skirmish to protect their transport ship.
Most of the characters in the Clone Wars series have good reference sheets, or at least some decent artwork done of them. To my (and I'm sure many peoples) dismay, there is NONE of Echo in his awesome ARC Trooper armor.
So here it is. A reference sheet made by studying the ARC Trooper's armor, and watching the episodes with Echo's ARC armor to get the colors right. I'm 90% positive of its accuracy.
This is something I want to give to all of Echo's fans. I worked very hard on it, and it pains me that he won't be appearing in the show again. (Fives... stay alive... please!) Feel free to use it, but please give credit should you post it or use the artwork elsewhere.
