Krootox are a divergent branch of Kroot evolution that lacked the qualities to become the dominant species. Krootox are ground-dwelling herbivores and are far heavier than the normal Kroot. In battle, the Kroot lash large, unwieldy Kroot Guns to a Krootox's powerful shoulders and climb aboard its haunches to use the beast as a mobile weapon platform. Krootox are not aggressive creatures as a rule, but should an enemy attack their unit, they will fight ferociously to defend those they see as their herd brothers.

You may field a Krootox and its Rider in a Tau army by adding it to a Kroot Carnivore Squad.
