Harold (Fallout 1 / 2 / 3)

Harold, a ghoul like mutant who survived for hundreds of years due to the FEV he was exposed to... Later on in his life, a sapling began to speak to him and started to grow out of his head, that was Bob. He then befriended Bob. After years of travelling, he reached the Capital Wasteland, where he got rooted into the ground by Bob after taking a rest. Years later, a cult worshipped him and did not let him die even when he asked them. Then came The Lone Wanderer. Harold asked the Wanderer to kill him, and the Wanderer did as Harold wished. Harold met his peaceful end in 2277.
