After Zapper Zaku's two defeats, Grappler Gouf was sent into battle. He is easily the most intelligent and level headed on the invasion force trio (though still prone to silly antics), with ambitions to eventually take over Sazabi's position. After Sazabi's defeat, he and Destroyer Dom secretly got on board the Gundamusai in an attempt to rescue Zapper Zaku. They failed and were likewise drafted.
