Captain Brok Iron-Hide

Appearance
Captain Brok is a heavily cybernetic giant whose skin has been largely replaced by thick, riveted iron plates and brass tubing. His right arm has been completely removed and replaced by a massive, steam-powered piston that hisses and vents with every movement. He stands nearly twenty feet tall and weighs several tons.
Personality
Brutal, simple-minded, and fiercely loyal to General Kaelar, Brok is a soldier who loves the sound of metal crushing bone. He has little interest in strategy, preferring the visceral thrill of a frontal assault where his "Iron-Hide" can be truly tested.
Secret Motives
Before his "upgrades," Brok was a simple giantfolk blacksmith. He was convinced by Kaelar that the mechanical enhancements were necessary for the survival of their race. He now secretly fears that he is more machine than giant and pushes himself to greater acts of violence to prove he still has a "warrior's heart."
Combat Tactics
A melee powerhouse, Brok uses his piston-arm to deliver devastating blows that can shatter walls and send players flying. He is virtually impervious to non-magical physical damage and can vent a cloud of superheated steam as a reaction when hit, blinding and burning nearby attackers.
