Roy

Commander Roy was a Clone Commander during the time of the Clone Wars. He commanded the 8th Clone Trooper Legion under the command of general Ni Resh.

Geonosis
Commander Roy arrived late to the battlefield as backup for the main force. He and the 8th served under Master Yoda then. He led them as they participated in the Mesa Battle, and provided support for the 501st.

Assignment
Commander Roy was assigned to the 72nd Sector Group to defend Krashagg. He was on the ground during that battle, and fought alongside General Resh in the thick of battle. He also led a squad through Sullust while they invaded it. During his time with Ni Resh as they took a tour through the outer rim, the two began to understand each other, and the Legion began to fight more effectively as Clone and Jedi worked together. It is unknown how Roy responded to the call for Order 66, but he did oversee the battalion of troops at Yaga Minor during the Galactic Empire.

Behind the Scenes
Commander Roy was originally from a squad in the Star Wars Miniatures game, and was just a named Clone Commander in that squad. Later, he was put in a campaign in a RPG, and was given his phase two armor from another mini in that squad.
