Chosen One

The Chosen One is the grandson/granddaughter of the Vault Dweller and the player character in Fallout 2.

Family ties
The bloodline of the Wasteland's most influential tribesman extends all the way back to the Vault Dweller and his spouse, Pat. As the son of the Village Elder, the Chosen One is a member of the third generation of former Vault 13 dwellers living outside the Vault, similar to how his grandfather was the third generation to live in a Vault.

The quest
The Chosen One was trained from birth to become the tribe's champion and, in the future, their Elder. Part of these trials were drug sessions with Hakunin. The final stage of the Chosen One's development was the Temple of Trials, a trial the Chosen One's mother also completed long ago. After completing his training, the Chosen One was sent out by the people of Arroyo to find a Garden of Eden Creation Kit which could make the failing village thrive once more.

Exploits in the Wasteland
In the course of the Chosen One's journey, he changed the wasteland in many ways, both great and small.

In Klamath, he made them a little more exciting for some time.

In Modoc, he ruined the town's unique cuisine by shooting Rose's domesticated deathclaw in the eye.

In Vault City, John Cassidy joined his journey.

In Broken Hills, he exposed the anti-mutant conspirators' attempt to rid the town of super mutants, thereby earning the loyalty and friendship of the sheriff, Marcus, who joined him on his quest.

In New Reno, he sired an illegitimate son, who would eventually become the feared and powerful leader of the Bishop crime family.

In Sierra Army Depot, he repaired Skynet, which joined to him.

In Vault 15, he killed Darion, leader of the New Khans, thereby freeing the local squatters from the gang's tyranny, and quickened the expansion of the New California Republic by helping to strike a deal between the squatters and the NCR government, which further resulted in the Khans getting hunted to near extinction for the second time.

In Navarro, Drill sergeant once caught him without his uniform. Chosen one freed Xarn and repaired motivator K-9 and left him in NCR so that he could receive necessary repairs from Dorothy.

The Enclave
Eventually the Chosen One found the GECK, but he also discovered that there was more at stake than just the future of his village, as the Enclave, a remnant of the old United States' shadow government, abducted the people of Arroyo, in order to develop a FEV specimen, which they would use to commit a genocide on the population of the Wasteland, as they in the eyes of the Enclave were unpure mutants.

The Chosen One eventually found the Enclave's headquarters, an old Poseidon Energy oil rig in the Pacific Ocean, which he reached by an old oil tanker. Here he freed his people as well as the inhabitants of Vault 13, who were also abducted by the Enclave for their experiments. As the Chosen One made his escape, he was faced by the fearsome and mutated secret service agent, Frank Horrigan. He managed to slay Horrigan, who revealed that he had activated a nuke to blow up the entire platform, but this was unable to stop the Chosen One who escaped on the oil tanker along with the tribals and the Vault 13 dwellers.

Legacy
With the GECK in his hand the Chosen One, along with the Arroyo tribals and the Vault 13 dwellers, founded the city of New Arroyo and reunited the two bloodlines that had been separated for three generations. The Village Elder, pleased with the reunion, found peace and passed away a few months later, leaving the leadership of the village to the Chosen One.

With the combination of the vault dwellers' technical knowledge, and the tribals' survival skills, New Arroyo thrived under the Chosen One's rule, and grew into a powerful civilization.

Marcus, in particular, was inspired by the Chosen One's example, and after the uranium mine in Broken Hills ran dry and the place was deserted, he wandered east, eventually founding Jacobstown in the Mojave Wasteland. The Courier may ask about The Chosen One to which Marcus replies he never found out what happened to the Chosen One after their group split up, but had a feeling that everything worked out for him in the end.

The Chosen One was also remembered by other individuals. While not being born at the time it happened, Klamath Bob still would tell stories about the tribal that visited the town of Klamath and stirred up the place, and Cannibal Johnson would reminisce of his visit to Navarro.
