Scrapjaw

Scrapjaw- Mek of mahem he lost half his face and his entire right arm in an explosive “accident”. Most would’ve died. Scrapjaw rebuilt.

Now, he’s the Master Builder. His metal jaw crackles with energy, able to crush helmets or weld plates with equal ease.
More than a fighter, Scrapjaw’s a creator of chaos: war machines, armored beasts, and scrapyard fortresses that walk on spider legs. He doesn’t just make things to work, he makes them loud, mean and impossible to forget.

When the orcs go to war, they pray Scrapjaw’s machines break after the enemy does.
