Slader is a Holy Knight of Liones, and the captain of the infamous Roars of Dawn. A natural leader; Slader was shown to have great patience, both when dealing with a dangerous enemy or instructing his less experienced comrades. When undergoing a mission, Slader is entirely focused on achieving success at any cost. His tenacity to see the mission reach completion is shared with the other members of the Dawn Roar, best shown when they stood motionless for over half an hour in wait for the Armor Giant to strike. He has a medium-high voice.
