Tinker Joe

Tinker Joe is a merchant in Fallout 3. He sells a robot companion (Sergeant RL-3) for the price of 1,000 Bottle caps near the RobCo building if the player has a neutral karma. .

Tinker Joe is armed with a laser pistol and accompanied by RL-3, a Mr. Handy, and a Protectron robot. Despite his sizable entourage, he has a tendency to wander around in the Wasteland area near the RobCo Factory, where he runs the risk of getting attacked and mauled by a randomly spawning Yao Guai.

If he is dead you will not be able to acquire Sergeant RL-3.

If you blow up the Megaton bomb and Tenpenny begins his sniping practice there is a chance Tinker Joe will be one of his targets and end up with his head splattered.
