CT-2643 Marvin

CT-2643, otherwise known as Marvin. Like everyone else, he was born on Kamino. He was originally stationed on a Venator ship, and served under the 501st battalion for quite a while, even becoming a pilot among their ranks. Eventually, the ship was caught in a severe attack, causing it to be destroyed. Marvin barely survived the attack by managing to crash land his ARC-170 onto the planet of Felucia. Hoping to be rescued, he set up camp in the wilderness, preparing for a long wait. In his good fortune however, A clone patrol was en-route to Felucia to look for CIS forces. When they came across Marvin, they were in shock to find a clone in the middle of nowhere. The clone patrol quickly boarded him onto a LAAT and flew him off the planet for him to get medical treatment. After a couple days in the bacta tank and some physiotherapy, Marvin was right back and ready to go. 
When Marvin was questioned about what happened, he couldn't remember much from the attack. All Marvin could remember was watching in horror as the Venator he had served his whole life on, was obliterated into millions of pieces. 
Marvin was asked if he would like to rejoin the 501st and take to the skies again, but Marvin said no. Marvin wanted to take a different approach at life, so he remained as a basic clone. One day, when everyone was lining up for a mission, two other 101st clones were acting up and wanted Marvin to go mess around with them. Marvin, wanting to set a name for himself, declined to join them. Upon seeing this, Commander Cody went up to Marvin and asked if he'd be wiling to join the 212th battalion. Marvin, wanting to refuse at first, felt a sudden rush of emotion. Marvin accepted Cody's offer and joined the 212th battalion.
Marvin served as a regular trooper in the 212th until he hit the rank of specialist. At that rank, he went to become a medic. After becoming a medic, Marvin expressed interest in Joining the 2nd Airborne Company. Marvin passed the 2nd Airborne tryouts with flying colours, with the help of a fellow trooper also trying out.
In a mission the 2nd Airborne performed, Marvin was getting ready to jump from the LAAT, when a blast from a droid hit him right in the right eye. Marvin was evacuated and was brought to a medical station where he was treated. Marvin miraculously survived, however his eye was permanently damaged.
With Marvin having a foothold in a new welcoming life and the resignation of the 2nd Airborne ARC trooper, Marvin decided to set his sights upon the position. 
Candlewax, the lead ARF trooper, basically took Marvin under his wing and recommended he tried out for ARF to get a stepping stone into ARC. Taking his advice, Marvin did. 
Upon entering the tryouts, Marvin was nervous. He was never very good at climbing, and with his damaged eye, he was scared about how he would perform. despite his handicap, Marvin proved to perform well in the tryouts, even managing to surprise himself by beating the obstacle course. Marvin had gained one step closer to his goal, by becoming a trainee ARF. Marvin's first mission as an ARF trooper was, less than pleasant. the second mission Marvin performed in as a trainee ARF, was when the base was evacuated due to an infection outbreak, the Anaxes base was moved to a temporary base, where they had to defend it from intense amounts of CIS forces. Marvin took the high ground and was able to pick off droids easily, helping his fellow troopers. Marvin was promoted to Lance Corporal after that mission, and since then has been practicing continuously to achieve his goal.
