Rattletrap - Clockwerk Goblin

The by-product of Goblin technological weapon research during the old War, Rattletrap the Clockwerk Goblin was shut away into storage for countless decades until the Sentinel found and reactivated him. Combat-wise, this goblin's capabilities know few bounds; his body is stocked with a huge array of armaments that destroy targets both near and far with ease. His trademark wrench can even extend itself like a grappling hook, allowing him to pick off individual targets with pin-point accuracy.
