Build Dangerous

Thanos is a building inspector. He is also immortal, which is the only reason he still has the job. Every building in town is about to open, and every owner has the same plan: cut the ribbon, let the crowd in, and hope nobody finds the live wires, the hungry guard ferret and the "NOT A COMPACTOR" room before the insurance runs out. Thanos's job is to find every trap first. Since nothing can kill him, the quickest way to make a trap safe is to walk up to it and set it off. Then he signs the room off and moves on, while the crowd outside gets more impatient by the second. He is immortal. Unimpressed. On duty.
