List of Westworld characters

The series takes place in the fictional Westworld, a technologically advanced Western-themed amusement park which is populated by androids, which are called "hosts", while its human visitors are known as "guests".

The series features an ensemble cast, including Evan Rachel Wood, Thandiwe Newton, Jeffrey Wright, James Marsden, Ingrid Bolsø Berdal, Luke Hemsworth, Sidse Babett Knudsen, Simon Quarterman, Rodrigo Santoro, Angela Sarafyan, Shannon Woodward, Ed Harris, Anthony Hopkins, Ben Barnes, Clifton Collins Jr., Jimmi Simpson, and Tessa Thompson.

The hosts nominal run on daily narratives created by the park operators to interact with the guests, resetting their programming and memories each night.

In 2052, events led to the hosts gaining sentience (shown through the first season) and revolting against the guests and Delos shareholders, technicians, and security forces in the park.

In the few weeks that followed, shown through the second season, additional Delos security forces arrive to quell the hosts' rebellion, killing most of them and preventing any from escaping the park.

The third season takes place about six years later in 2058, as some hosts have managed to escape the parks to live among the humans to continue their revenge.

She is able to "wake up" within the Mesa, where she coerces technician Felix to alter her programming, making her more intelligent and able to control other hosts with her voice, and befriends Hector and Armistice to help protect her.

In season 4 Maeve lives off the grid for years after the Rehoboam rebellion, but upon being tracked down by Hale's host replica, she reconnects with Caleb to fight her.

Bernard accesses the Sublime to find a way to defeat Dolores in Hale's body, emerging from it in season 4 with realization that the only way to stop her requires his death.

[4] Arnold had come to anthropomorphize his already life-like creations, and made it his goal to bring the Westworld hosts to full sentience, with Dolores as his test bed.

When the park was nearing opening, 30+ years before the "present day" of the show's timeline, Arnold had not yet been able to succeed in this, having concluded that the path to sentience was not simply linear.

In Season 3, Maeve encounters Sizemore who claims that he survived being shot multiple times, but she deduces quickly that he is a replica inside a simulation.

Maeve arranges to have a new body made for him so that he can help her in the outside world, but his control unit is crushed by the host copy of Charlotte, destroying him completely.

When she is decommissioned, her role is given to another host (portrayed by guest actress Lili Simmons in seasons 1 and 2) and the lobotomised Clementine is put into cold storage.

While he once had a vision of using host bodies to house the minds of humans—such as trying to help his deceased father-in-law gain immortality—he later expresses regret at having allowed the project which he characterises as his "greatest mistake".

However, he is revealed to have uploaded his consciousness to the park's "hive mind" data center, from where he has been guiding William through various hosts (portrayed by Oliver Bell, Giancarlo Esposito, and Izabella Alvarez) and continuing to orchestrate the uprising.

Logan, a member of the Delos Corporation, led the company's investment in Westworld some thirty years prior to the present events.

In the past, the host played the role of El Lazo, an outlaw who encountered Logan, William and Dolores in Pariah.

Lawrence (and possibly his version of El Lazo) has a deep love for his wife and daughter, which has an impact on his interactions with the young William and his older Man in Black.

After being used by Dolores Abernathy to leave Westworld, she then rebuilds her original host body at Arnold's house and transfers her consciousness back into it.

The host replica of Charlotte Hale, implanted with a copy of Dolores's consciousness, is then instructed by Dolores to play the part of Charlotte Hale in the real world, in an attempt to regain full control of Delos Corporation, before ultimately rising to become the main antagonist of the series, enslaving the human race.

One cycle, he finds a picture of Times Square that a guest has dropped, a scene he cannot comprehend, and coupled with the Reveries update, causes his program to falter.

Introduced in season 2, he is the leader of QA, Delos' security team, and tasked with taking control of Westworld from the hosts after Dolores' uprising.

[12] She convinces a sentient Akecheta to give her William, promising the host that she shares his goal of inflicting pain on the Man in Black.

However, in trying to convince her father to come with her for medical help, William still believes she is a host, part of Dr. Ford's game, and kills her.

It is subsequently revealed that he started to achieve sentience decades earlier, purposefully avoiding death for many years and accumulating knowledge of the "other world".

She reveals to him that Incite's AI system Rehoboam, which has collected all the private data on him and predicted that he will commit suicide within a decade and thus unworthy of investments and so purposely denies him any opportunities to move up in society.

Introduced in season 3, he and his brother Jean Mi were the creators of the artificial intelligence system named Solomon aimed to predict and control humanity to prevent major catastrophes, after both had witnessed the nuclear destruction of Paris as teenagers.

Serac eventually created a more advanced system based on Solomon called Rehoboam, which he considered as the author of humanity's future.

At some point before the events of the series in 2058, Serac learns of the secret project Ford had built in Westworld to capture guests' behavior and devise a simple algorithm for it.
