Captain Grumpf is a minor character in the game and serves as one of the first antagonists that Red encounters. He is found after Red becomes visible to the Kurvaz Battle Cruiser that Grumpf is aboard. He is a captain who's working with Kurvaz Soldiers. He shoots missiles at Red, not caring that he is damaging one of his own ships. He is eventually taken down by his crew members, who realise that he is destroying a Kurvaz ship. He speaks with a heavy German accent and lisp, as shown by the text displayed when he talks.
