King Battler commands a profit-driven poacher group targeting newly emerged dinosaurs, serving as the series' primary antagonist. His organization utilizes advanced armored vehicles, notably the eponymous King Battler and the Wildcat, which repeatedly confront the Born Free Team's conservation equipment in direct opposition.

His daughter, Lady Battler, actively participates with matching antagonistic motivations, adding a familial layer to the conflicts through her vengeful pursuits against the Born Free Team.

King Battler consistently displays hostility toward dinosaur conservation, cementing his group as a persistent series-wide threat. His operational strategy relies on deploying technologically enhanced machinery to capture or eliminate dinosaurs, systematically creating obstacles for the protagonists' missions.
