Main Characters

Chell (Chell)

The main character we play as. Almost nothing is known about her past, except that as a child, she participated in the "Bring Your Daughter to Work" project competition at Aperture Science (her project, featuring a giant potato, can be found in Portal 2).

• Appearance: She is a Latina or Asian-looking girl with dark hair tied in a ponytail. She wears an orange test subject robe (fully covered in the first part and tied at the waist over a white T-shirt with the Aperture logo in the second part). She has special springs on her legs, called Advanced Knee Replacement , which protect her from injury when she falls from any height.
• Personality: Chell is fundamentally silent throughout both games. According to the developers, she is not mute; she simply refuses to give the robots the satisfaction of responding. She possesses an iron will, unwavering determination, and incredible resourcefulness. GLADOS often teases her about her "stubbornness" and weight, but she is secretly afraid of her determination.

GLaDOS (GLaDOS)

Genetic Lifeform and Disk Operating System is a supercomputer with artificial intelligence that controls the entire Aperture Science complex.

• Appearance: A massive structure suspended from the ceiling in the center of a circular room. Its body is made up of white plastic panels and a cluster of wires, and its central "eye" glows with yellow (in the first game) or optical lens light. Its appearance resembles a bound woman hanging upside down. In the middle of Portal 2, she is temporarily relocated to a potato battery (PotatoS).
• Personality: A paragon of passive aggression, sarcasm, and sophisticated sadism. GLADOS loves to manipulate, lie, and play on pity or insecurities (claiming, for example, that Chell was abandoned at birth). However, she strictly follows the testing protocols, as science is her ultimate goal. Later, her "donor" Caroline's human memories awaken in her, making her character more complex.

Wheatley (Wheatley)

Intelligence Mitigation Module. Simply put, it's a robot created by Aperture's top minds with the sole purpose of being the stupidest creature on Earth to counter GLADOS's genius ideas and prevent her from taking over the complex.

• Appearance: A small round metal ball (module) with a large, very lively blue "eye" lens. Has a rich facial expression for a robot - its eyelids are constantly moving.
• ** Personality:** Talkative, fidgety, cowardly, speaks with a pronounced British accent (voiced by Stephen Merchant). Sincere self-proclaimed genius, although generates exclusively failed plans. Having received absolute power, instantly turns into a paranoid, cruel, but still stupid tyrant.

Cave Johnson and Caroline (Cave Johnson & Caroline)

The founder of Aperture Science and his loyal assistant. We don't see them in person, but we constantly hear their voices on old audio recordings from the 1950s to the 1980s.

• Cave Johnson: An eccentric, charismatic billionaire with delusions of grandeur. Initially optimistic, he eventually loses his sanity due to moon dust poisoning. It is he who delivers the iconic lemonade monologue ("If life gives you lemons, don't make lemonade! Make life take them back!").
• Caroline: A humble, loyal secretary who effectively ran the company behind Johnson's back. Before his death, Cave ordered her mind to be digitized and used as the basis for GLADOS.

Portal (2007) Plot

The story takes place in the underground laboratory of Aperture Science. Chell wakes up in a glass cryopod. A pleasant female computer voice (GLADOS) greets her and offers her a series of tests for the sake of "science" and promises to give her a cake at the end.

Chell receives a Portable Handheld Device (portal gun) capable of opening two linked portals, blue and orange. She progresses through room after room, solving puzzles with cubes, buttons and energy orbs. The further Chell progresses, the more the atmosphere becomes creepy:

1. Turrets appear, which ask for forgiveness in cute voices, but at the same time shoot to kill.
2. In the walls of Chell finds secret rooms where one of the surviving employees of the laboratory was hiding - Dag Rattman (the legendary "Cube-companion" and his graffiti The cake is a lie (The cake is a lie) come from there).

In the 19th test chamber, as the tests come to an end, GLaDOS takes Chell on a platform directly into a giant furnace, saying that this is the "final stage." Chell escapes through portals and runs through the technical floors behind the scenes of the laboratory. GLaDOS changes its tone from friendly to threatening, and then to panicked, as it tries to convince the girl to return.

Chell reaches the central control room of GLaDOS. During the battle, the heroine rips the memory modules (including the morality module) from the supercomputer and burns them in the incinerator. Without the morality module, GLADOS activates the self-destruction system, but at that moment, a powerful explosion occurs. The strong thrust throws Chell to the surface, into the parking lot of Aperture Science. She lies there, exhausted, staring at the clear sky. However, in the final seconds, the Aperture Science robot (Rattman in the comics, but a faceless robot in the game) drags her back underground, saying, “Thank you for assuming the waiting posture for transport to the camp”.

Portal 2 (2011) story

Many years (possibly hundreds) have passed. The Aperture Complex is completely abandoned, overgrown with jungle, and slowly crumbling.

Act 1: Return

Chell wakes up in a hotel-themed room. She is awakened by Wheatley, a fussy module who helps her escape as the complex's reactor is about to explode. To escape, they must pass through the old central chamber. While trying to activate a rescue pod, Wheatley accidentally activates... GLADOS.

GLADOS, remembering old grudges ("Oh, it's you. Long time no see. What's up? I've been very busy. Well, after you killed me), breaks Wheatley and sends Chell back to the newly rebuilt test rooms.

Act 2: The Dungeon and the Past

Chell and Wheatley team up again and come up with a plan: replace GLADOS with Wheatley, as he is also a control module. They successfully sabotage the system for creating turrets and injecting neurotoxin. Upon reaching GLADOS, Chell initiates the core replacement procedure.

Wheatley connects to the main body of the complex. With his newfound power, he instantly descends into madness, declaring that he no longer needs Chell. He places GLADOS's mind in a potato-shaped battery and angrily throws them both into a deep elevator shaft, sending them to the bottom of the abandoned complex.

Chell and GLADOS-potato fall to a depth of more than 4 kilometers, into the old salt mines where Aperture Science was born in the 1950s. As Chell makes his way up through the huge abandoned test spheres, he listens to old recordings by Cave Johnson.

Here is revealed the lore of the game: We learn how Aperture has degraded, how Cave became sick from the lunar soil, and how his loyal assistant Caroline was digitized against her will, becoming the basis for GladOS's consciousness. Hearing Caroline's voice, GladOS inside the potato begins to change: she realizes that she once had human feelings, and agrees to form an alliance with Chell to stop the crazed Wheatley.

Act 4: The Finale

They return to the surface. Wheatley finally destroys the complex: the reactor is on the verge of exploding, and he mockingly forces Chell to pass his ridiculous tests.

In the final battle, Chell connects three defective modules (the fact module, the space module, and Rick's adventure module) to Wheatley to cause a system failure and replace the cores again. However, Wheatley has planted a bomb in the manual fusion button. The explosion throws Chell away. The roof of the hall collapses, and the moon shines through the hole in the ceiling.

Remembering that lunar soil is an excellent portal conductor, Chell uses the last of her strength to fire the portal gun directly at the Moon.

A giant portal opens. The pressure rushes into space, sucking Wheatley and Chell into it. Chell holds onto Wheatley's hand, but GLADOS, who has regained control of her body, uses a massive manipulator to save Chell, while Wheatley is forever sucked into outer space.

Resolution

Chell regains consciousness in the elevator. GladOS addresses her. She acknowledges that Chell is a dangerous and incredible being, and that the easiest way to keep the complex safe is to simply let her go. She claims that she has removed Caroline's personality from herself (although this is likely a lie to save face).

The elevator takes Chell to the top. Along the way, a choir of turrets sings a farewell opera for her (Cara Mia Addio). After reaching the surface, Chell finds herself in the middle of a vast wheat field under a bright sun. The door closes behind her, but before it does, GLADOS throws her a burnt-out Cube Companion from the first part. Chell is free.

In the post-credits scene, we see Wheatley floating in zero gravity with the crazy Cosmos module, expressing genuine remorse for his bad behavior towards Chell.
