Be Kind to the Smoothskins. One Saved the world once. 'Course, they broke it to start with.— Harold

Harold is a very special mutation - originally a human from Vault 29, he was exposed to F.E.V. during an exploration of a military base called Mariposa. Initially, he mutated into what looked like an ordinary ghoul, and later distinguished only by a tree growing out of his head. By 2277, he is but a gnarled face in a tree growing in the Oasis Grove. During his many adventures, he has encountered such influential people as Richard Grey, Vault Dweller, Chosen One and Lone Wanderer.


Early life

Harold was born in 2072 and was only five years old when the Great War started and he was forcibly locked in Vault 29[1].

Gametitle-VBThe following is based on Van Buren and has not been confirmed by canon sources.

Harold's home, Vault 29, was initially populated by young children which were brought up by Diana, a human brain connected to a supercomputer, who posed as a goddess to its inhabitants. In cases of population unrest a test subject would be chosen to be released from the Vault early. The subject would return and tell the Vault dwellers the condition of the world outside and whether or not it was safe to leave the Vault. Of course, the test subjects would never return and this fact would deter anyone leaving again for a while.

Harold was one such subject, selected in 2090. He was released from the Vault, stunned by the security system, and picked up by a robot to be taken to the Nursery, where Diana resided. At the nursery he was given the choice of staying with Diana or exploring the outside world. However, if he chose to explore, she would have to 'condition' him so that he could not reveal anything about her or the nursery to the world.

Harold agreed to stay with Diana but managed to escape. During his travels he kept the nursery a secret because he felt it was his duty to the world to keep such a future 'gift' intact until the world was ready for it[2].

Merchant career

After leaving his home Vault, he began a successful career as a trader and merchant, venturing across the wastes. Eventually though, as he became an important player in the Hub, he began to notice the increasing frequency of mutant animals attacking his caravans. Frustrated, he decided to deal with this.

Mariposa Military Base

Harold and a group of other adventurers--among them a man named Richard Grey, a doctor living in the Hub who was equally perplexed by the strange mutants--tracked the mutant population and eventually found its source: an old military base that seemed to be spawning mutant critters.

Inside, most of them found death, killed by all the mutants that littered the base as well as its automated security systems. Harold, Richard, and a few others made it fairly deep into the base, where they found immense vats filled with a strange thick, green solution (F.E.V) that seemed to be mutating the animals. A large robotic arm knocked Grey into a vat, where Harold assumed he died (actually, he became the Master). Harold himself was knocked unconscious. He awoke some time later out in the desert, already starting to mutate. A caravan eventually found him and brought him back to the Hub, where he settled into a destitute existence.

A mutant down on his luck

The Vault Dweller first met him in the Oldtown section of the Hub. Oldtown was the part of the Hub where the poor lived as well as a moderate ghoul population. Harold is one such mutant and he makes a living begging for spare change. In exchange for some money, Harold provides the Vault Dweller with a great deal of information, mostly dealing with the Mariposa Military Base and Richard Grey, as well as the deathclaw that lives near the Hub that Butch Harris, leader of the Far Go Traders, needs you to deal with.

Sometime between 2162 and 2242, a small tree (which he calls Bob, although he likes to joke that his name is Herbert) began to grow out of the side of Harold's head, showing that even the sterile mutants can be the source of some kind of life. It is an entirely new species of tree - unique and special, just like Harold.

Traveler of the Wasteland

FOBoSLogoThe following is based on Fallout: Brotherhood of Steel and has not been confirmed by canon sources.

After the destruction of the Master army, Harold left The Hub and became a traveler who visited various places around the Wasteland. It's known that he traveled in Texas to Carbon and the ghoul city called Los around 2208. He had a sexual encounter with Carbon's prostitute, Ruby, and he lost a hand, a toe and an eye, which fell off his body. Harold's travels ended in Gecko in 2241.

Leader of Gecko

Gecko power plant

In 2241, the Chosen One, grandchild of the Vault Dweller, runs into Harold again in Gecko, the ghoul town not far from Vault City. After the destruction of the Necropolis following Fallout, most of the ghoul population of the town migrated far north to form a settlement around an old nuclear power plant built by Poseidon Oil before the War. Anyone else would likely be killed by long term exposure to radiation, but the ghouls just find it pleasant. When Harold arrived, the plant was being run dangerously and stupidly. Harold quickly took over from the well-meaning but inept leaders of Gecko and got the reactor into some kind of working order. When the Chosen One arrives in Gecko, Harold asks him to help fix the reactor. To do so, the Chosen One must secure the aid of Vault City's officials, which is no mean feat.

You still hear mention of Harold from time to time. Apparently, the tree growing from his head has gotten larger, and if rumors are to be believed, fruit is growing from it. The seeds are said to be remarkably resilient, and several of them have taken root even in the most barren stretches of the wasteland.

Back home

Gametitle-VBThe following is based on Van Buren and has not been confirmed by canon sources.

By the 2250s, Harold was ill. The tree in his head developed an unknown disease and was dying. Much to his surprise, Harold found himself affected as well. He didn't think he was going to die, but, he just didn't feel right in the head.

So, he set out on a quest for a cure. Naturally, he didn't have an easy time of it either. People just didn't seem to want a mutant around any more. But, Harold didn't let that stop him. He persisted in his quest until he came upon the Twin Mothers tribe, which originated from his home, Vault 29.

Much to his surprise the tribe took him in and accepted him as he was. He explained his quest to the tribal leaders and was told that they would consult their goddess. Days later, Harold was approached by the tribal shaman and given a potion to drink. It was a foul concoction, but it worked. Bob, the tree, got better and was happy again.

Harold couldn't let such a good deed go unrewarded so he offered to help the tribe in any way that he could. They smiled at him, thanked him, but declined his help. "The goddess will provide," they always said. Harold, nice mutant that he is, said that he would like to pay his respects to the goddess. He was taken to the tribal shrine and granted a private audience. He wasn't really surprised when the projected image of a woman appeared before him, but he was taken aback when she told him where he could find her. His return to the nursery was a moment of joy for Diana and a 'new experience' to him, as much of his early memories faded with age.

Harold traveled to the Nursery and spent considerable time there, He even considered settling down and spending the remainder of his day in the tranquility of the gardens. However, eventually he left and traveled even further East.

If the Prisoner gave her the information on FEV and New Plague from the Boulder ZAX, Diana would be able to create a cure to the New Plague virus in the form of a small fruit, by genetically engineering it from Harold's tree.

FO3 Harold

Harold becomes a tree

Harold eventually found himself overwhelmed by the growth of Bob, and he became rooted to the ground during his travels in the Capital Wasteland region. Here he was discovered by several people who began to worship him as a god, and a small and exclusive cult known as the Treeminders began to form in secrecy. Bob began to blossom and many plants grew in this area, which became green with life, a stark contrast to the outer Capital Wasteland. During this period, Harold developed an alarmingly powerful mutation which enabled him to "see" the area around Oasis, through the very trees that came from Bob's seeds.

He would go on to use this ability to bring in wanderers, all the while hoping one of them would put an end to his troubles- unfortunately, the Treeminders' strange ways and insistence on using an intoxicating, potentially poisonous "sap" (as a "purification" ceremony) drove off most of them, many in worse mental shape than they were prior. His persistence would pay off when the Lone Wanderer came into view--on his orders, the Treeminders allowed the wanderer safe passage into Oasis.

Harold revealed his true identity to the Wanderer, and begged for mercy; after being stuck in the same position for decades he was eager for death. The other dwellers of "Oasis" either ignored or, in their religious fanaticism, interpreted Harold's wishes as a moral and spiritual test, much to Harold's chagrin-- thus his only recourse was to ask the Lone Wanderer to take his life. However, two members of the Treeminders (namely, the leader of the cult and his wife) are found arguing about Harold. The leader of the cult wishes for Harold's gift of plant life to be kept safe and confined to Oasis, while his wife wishes for Harold's gift to be shared and spread throughout the Wasteland.

They each ask the Lone Wanderer to accomplish their own wishes, and the Lone Wanderer must decide whether to carry out Harold's wish of death, the cult leader's wish of keeping Harold's spreading growth confined to just the Oasis, or the wife's wish to spreading his glory across the Wasteland. A fourth, more negative option of setting him on fire also exists-- this will draw hostility from all the Treeminders. Through granting Harold's wish, the Lone Wanderer's skin will be as hard as Harold's. If granting the optional wishes, Harold will be spoken to through a variety of dialogue, one of them being that he has been given a gift and must stay alive to save the lives of others. Harold, finding a new reason to live, replies that he was selfish to want to kill himself, and then asks Bob if he agrees.

Nature of Harold

FO02 NPC Harold N

To the untrained eye, Harold appears to be an ordinary ghoul. This is not so, however. Ghouls are the result of massive and/or long-term radiation damage to a human body; Harold is a product of the Forced Evolutionary Virus. Unlike most people who are exposed to FEV, Harold did not become a super mutant, but is the result of a unique combination of radiation damage from constant low-level environmental exposure, indirect exposure to FEV (it is unclear how Harold was infected with FEV as he blacked out for a while) and a fair amount of random chance. Thus he's not a ghoul, and he's certainly not a super mutant. To quote Tim Cain, "Harold is special."

Furthermore, Tim Cain has this to say on the subject: "As for contact [with FEV], any contact at all will infect the subject, but the amount of contact determines the result. For example, I imagine Harold had some contact with the virus, but he was not fully immersed in it, so he became a different mutant than the Master's subjects. Full immersion, of course, is the preferred method of infection, as it provides the virus a large surface area for infection."

Another similar FEV-created, ghoul-like mutant is Talius.

It is interesting to note Harold's unusual behavior in treating Bob as if the plant were actually sentient. Although at no point does the plant indicate that it can convey feelings, Harold certainly is not stupid, and perhaps only crazy in the humorous sense--yet he still insists on hearing out the plant's opinions on certain matters that he might otherwise take seriously. Given Harold's new found ability to "see" through the trees that are descended from Bob through the use of extreme concentration, it may not be much of a stretch to suggest that the two are deeply linked in some unknown way, almost certainly as a result of FEV exposure. Because of his mutation, it is no surprise that Harold is afraid of fire.

Despite his appearance, Harold is a kindhearted soul with a comical personality. He has made many friends throughout his travels, potentially including the Vault Dweller, the Chosen One, and the Lone Wanderer. He is also good with kids, as evidenced by his friendship with Sapling Yew in Oasis, of whom he is particularly fond.

Daily schedule

In Fallout 3, Harold doesn't get up to much in his day-to-day business, being fused to the ground. He can sometimes be seen chatting with Sapling Yew, a child of whom he is particularly fond.

Harold reveals his true identity to the Wanderer, and begs for mercy; after being stuck in the same position for decades he is eager for death. The other dwellers of Oasis either ignore or, in their religious fanaticism, interpret Harold's wishes as a moral and spiritual test, much to Harold's chagrin - thus his only recourse is to ask the Lone Wanderer to take his life. However, as always, there are competing interests at play. The leader of the cult wishes to keep Harold alive and safe, a secret for only Oasis, whereas his wife wishes for his gift to be shared and spread throughout the wasteland.

It is left to the Lone Wanderer whether to carry out Harold's wish of death or assist the cultists. A player with a high speech skill can convince Harold that he has a gift and his continued existence will vastly improve the lives of others. He will reconsider his wish for death and find a new reason to live. Of course, the Lone Wanderer can also just set about him with a flamethrower and bring him to a more painful and violent death than even he had hoped.

Harold appears in Fallout, Fallout 2, Fallout 3, and Fallout: Brotherhood of Steel. A ghoul named "Harold" with a tree growing out of his head appears in Fallout Tactics, although it is unclear whether this is actually the Harold.

Additionally, Harold was to appear in both Black Isle's cancelled Fallout 3 and Interplay's Fallout: Brotherhood of Steel 2. A cult called the Church of Harold is set to appear in Fallout Online.



Fallout 2


  1. Fallout Official Survival Guide
  2. In Fallout, asking Harold to "Tell Me About" 'Vaults', leads to his explaining that the vault he originated from failed due to an overabundance of vault dwellers and a lack of food to sustain their numbers. This actually corresponds to Vault 27, which was to be deliberately overcrowded by twice the sustainable amount, as opposed to No. 29.
