Sergeant Major Lemar Hoskins was a member of the United States Army and John Walker's partner. Once Walker became appointed as the second Captain America, Hoskins stood by his side as Battlestar. In 2024, Hoskins and Walker led the pursuit of the Flag Smashers on the behalf of the Global Repatriation Council. Along their way, they would be forced to work with Sam Wilson and Bucky Barnes, who were leading their own investigation. During a skirmish with the Flag Smashers, Karli Morgenthau punched Hoskins with excessive force, killing him.
