Lt. Lou Roher was one of the primary pilots and the second in command of the Midnight Fenrir Corps of the Principality of Zeon during the One Year War. He was known for his deep, cold voice and his quiet presence among the squad. Unlike his comrade Matt Austin, he rarely engaged in joking and banter, but he was recognized as the most skilled pilot in the Midnight Fenrir. He was the top cadet in his class at the Academy and the chief strategist of Fenrir.
Lt. Roher was born on Side 3 and attended the Zeon Military Academy. It is unknown, but probable, that he served in the Zeon Fleet during Operation British and/or the Battle of Loum. Afterward, he, along with his friend and mentor, Matt Austin, was assigned to the Fenrir Corps under Lieutenant Commander Gerhart Schmitzer. His primary mobile suit for the early part of his service on Earth was an MS-06F Zaku II. He participated in the attack on the North American air base and the capture of California Base. He was also on hand during the mission where Garma Zabi was KIA. Despite his normally cold and aloof nature, he had more confidence in ensigns Nikki Roberto and Charlotte Hepner than Austin did when they first started flying combat missions. He even took to encouraging Nikki sometimes after Austin's rather blunt declarations of un-confidence. During the lead up to Operation Odessa, he participated in the battle at the Gobi supply base and reconoitered the Trojan Horse at night. During these operation, as well as the retreat from Odessa, Roher piloted an MS-07A Gouf A type and a MS-06J Zaku II Ground Type. It was during this series of engagements that Roher and his teamates first encountered the Federation mobile suit forces. His next major operation after Odessa was the invasion of Jaburo, South America. He piloted an MS-07B-3 Gouf Custom during the assault and commanded the Fenrir Corps on the ground during the invasion. There he faced off for the first time against the RX-78-6 Mudrock Gundam, piloted by Fenrir nemisis Lt. Agar, and its carrier, the Blanc Rival. After the failure of that operation, Roher participated in the last defense of California Base in a MS-06F2 Zaku II F2 Type. After escaping, he fought in Fenrir's last action of the One Year War in the African desert. It is unknown, but probable given his skill as a pilot, if he survived the battle and with it, the One Year War. If he did survive, his later actions are unknown.
- Roher is one of 2 playable characters at the start of the game. He is assigned to blue team.
- There is some discrepancy in the depiction of his rank. He is addressed and named as a Lieutenant, but his cape shows the insignia of an Ensign (2nd lieutenant in gorund forces).
- He, like later addition to the team Manning is a skilled marksman, as he is able to use the 120mm and 90mm AR long range rifles.
