Slavegiant

The Slavegiant is a giant that the ogres have caught, broken, and put to work. Even an ogre thinks twice before wrestling one of these mountainous brutes into chains, but a tribe that manages it gains a towering engine of destruction, goaded to war beneath a great wooden yoke and a cargo of shrieking Gnoblars who prod and torment it from a swaying platform on its back. Half-starved, half-maddened, and wholly furious, the Slavegiant lays about itself with fists, feet, and whatever it happens to be carrying, as likely to flatten the Gnoblars steering it as the enemy it is aimed at. The ogres care little either way, for a rampaging giant sows terror wherever it treads. Kept hungry, beaten stupid, and loosed at the enemy line, it becomes a weapon of pure blundering catastrophe, one the tribe can always eat afterwards, should it finally fall.
