Boss-stompers take a more serious and disciplined approach to warfare, by Gargant standards. Their obsession with real fighting skill makes them particularly dangerous foes, adept at clubbing enemies into the dirt.

This box contains three Boss-stompers who can alternately be built as Rock-hurlers – Gargants that prefer to keep their distance and, as their name suggests, hurl rocks. The three Rock-hurlers also make up the new Spearhead army for the Sons of Behemat.
