I'll wait--I'll wait one hour, then I'll come back and, as soon as I can locate your dead body, I'll bury you. Alright? Brilliant! Go, team!... See you in an hour, hopefully! If you're not... dead.

The Intelligence Dampening Sphere, more commonly known as Wheatley, is a personality core of masculine programming and English West Country accent who appears in the single-player campaign of Portal 2.

He serves as the game's deuteragonist, guiding Chell through her efforts in escaping the Aperture Science Enrichment Center. However, half-way through the game he and GLaDOS switch roles as she becomes Chell's deuteragonist and Wheatley becomes the game's main antagonist.

Wheatley is voiced by British actor and comedian Stephen Merchant.


Wheatley was designed to be an Intelligence Dampening Sphere, one of the cores to be attached on GLaDOS in order to "generate an endless stream of terrible ideas" and inhibit her mental abilities. Although it was never explained, Wheatley was disconnected from her and given other jobs (it is possible that he was replaced by the Morality Core). Sometime before GLaDOS killed off the entire staff in the Portal 2: Lab Rat comic using neurotoxin, Wheatley had worked alongside staffs before he was put into storage with other cores seen at the end of Portal. After a few years, though under unknown circumstances, he was put into deactivation along with many other personality cores and kept in storage.

Thanks to Chell's havoc on the Enrichment Center via the destruction of GLaDOS at the conclusion of Portal, Wheatley and the rest of the cores were reactivated in order to maintain the facility. Ironically, this backfired as many cores appear to have been either killed off, gone insane (like the Space Sphere), or ran low on power.

Prior to the events of Portal 2, Wheatley was put in charge of maintaining the Extended Relaxation Center - which houses test subjects in long-term cryogenic stasis before and after they are put through the testing courses. However, what he did to actually manage the entire wing remains unmentioned. It was only until an unknown amount of time later that Wheatley decided to escape the facility. To accomplish this, he attempted to gather help from any remaining test subject that managed to last a long time after running out of cryogenic supply. Luckily for him, Chell was one of them if not the only one that lasted.

Wheatley's first appearance.

Wheatley is first seen during the very beginning of the game during the chapter The Courtesy Call, wherein he removes Chell from her Relaxation Vault and puts her into one of the old testing tracks, so she can find a Handheld Portal Device and help him escape. After she acquires the device, he meets up with her and detaches himself from his management rail to accompany her to the now-ruined Central AI Chamber, so they can access an escape pod to the surface. He uses his compatibility with the Enrichment Center's systems to allow passage through a testing chamber's backstage. When they reach the ruined Central AI Chamber and he tries to activate the lights, he accidentally reactivates GLaDOS instead. Wheatley is crushed by GLaDOS' pincers and tossed to the side and Chell is placed back in GLaDOS' testing tracks. However, he somehow survives and is placed back on his management rail, due to an incident involving a bird (Wheatley attempts to explain the events of this incident to Chell, but it is not heard in full).

Throughout Chapters 2, 3, and 4, Wheatley observes Chell from behind the scenes of the test chambers, trying to figure out a way to break her out. Finally, at the end of Chapter 4, he is successful and they both escape into the manufacturing section of Aperture, just before GLaDOS is about to kill Chell. He hatches a plan to sabotage GLaDOS' turrets and neurotoxin, then confront her, defeat her, and escape. They succeed in sabotaging GLaDOS' turret production line and neurotoxin generator.

Once this is done, Chell and Wheatley return to the Central AI Chamber through the Tubes to confront GLaDOS. The Announcer detects GLaDOS as a corrupted central core and offers a core transfer. A stalemate is reached between Wheatley and GLaDOS, and Chell has to push the Stalemate Resolution Button. Once Chell does this, the core transfer commences. GLaDOS' head is removed from her body and Wheatley is put in its place, putting him in control of the facility. He summons an elevator for Chell to escape to the surface, but just as the elevator is starting to rise, Wheatley grows corrupted with power and lowers it back down. He says spitefully that all Chell does is boss him around (Ironically, Chell never says a word in either game), but now he is the boss and she is at his mercy. Wheatley transfers GLaDOS' core programming to a small computer chip powered by a potato battery as an attempt to humiliate her. In her potato form, GLaDOS suddenly recognizes Wheatley's voice. She tells him that he is an Intelligence Dampening Sphere, "producing an endless stream of terrible ideas", essentially "designed to be a moron". In a fit of rage, he accidentally knocks both her and Chell into the bottom of the elevator shaft leading to the depths of the Enrichment Center, Old Aperture

The Enrichment Center during Wheatley's control.

After returning from Old Aperture, Chell and potato-GLaDOS learn that Wheatley's moronic actions are causing the facility's reactor to approach a nuclear meltdown because he consistently neglects the urgent warnings from the Announcer, instead preferring to think of ways to satisfy the testing addiction he gets from inhabiting GLaDOS' body, which he calls "the itch". One such (unsuccessful) endeavor is the creation of Cube/Turret hybrids, or "Frankenturrets" designed to autonomously walk onto buttons. When Wheatley discovers Chell and GLaDOS, GLaDOS attempts to overclock Wheatley's processors by forcing him to interpret a paradox, but the attempt fails as he isn't smart enough to even understand that it is a paradox at all, even his Frankenturrets understand this paradox, as they are seen twitching and sparking after the paradox is mentioned. When this attempt fails, Wheatley puts Chell and GLaDOS into his own testing tracks (most of them stolen from GLaDOS, and usually mashed together with other stolen tracks in a semi-failed attempt to make new chambers.) As they go through the testing tracks, he examines the rest of the Enrichment Center and discovers Atlas and P-body. Realizing he no longer needs Chell to continue testing, he sets a trap, with which he can crush her to death. However, Chell evades his trap, escapes the testing area, and prepares for the final confrontation with him.

When Chell arrives in Wheatley's chamber, Wheatley employs a four-part plan to destroy her: no portal surfaces, start the neurotoxin immediately, bomb-proof shields, and bomb launchers. This backfires, however, when Chell uses a bomb to shatter a pipe of Conversion Gel, then uses this gel to redirect bombs at Wheatley. Each bomb stuns Wheatley for long enough to attach a corrupted core onto him. Once this is done three times, Wheatley is corrupt enough for the announcer to initiate a core transfer. A stalemate occurs once more between Wheatley and GLaDOS, and Chell must press the stalemate resolution button to finalize the transfer. However, Wheatley had booby trapped it with explosives before the fight, as the fifth part of his plan, and Chell is flung from the button. The explosion dislodges part of the ceiling, exposing the night sky and the Moon. Chell shoots a portal onto the Moon, causing both her and Wheatley to be sucked into space, both of them holding onto the central core body in order to stay anchored on Earth. While they are suspended here, the core transfer is completed. GLaDOS returns to her original place as Central Core, knocks Wheatley off her body, and rescues Chell. Wheatley flies off into space, accompanied by the Space Sphere.

Wheatley is last seen in the epilogue after the end credits, with the Space Core orbiting him, where he wishes he could say he was sorry for all he did to Chell.


The Portal 2 aesthetic theme is showcased in Act 4 of the single-player campaign. It is characterized by either mass-scale destruction of the chamber, or a regular clean theme with the occasional behind-the-scenes peek, also including Monitors. The walls are torn apart and the player can see all sorts of things outside of the chamber: Gel pipes, Pneumatic Diversity Vents, other chambers, catwalks, and sometimes fire. Each test is monitored by Wheatley shown on a screen. Soundscapes include intense destruction sounds: metal wronks, banging, and groans. This is the last theme the player will encounter in the Portal 2 Single Player campaign. The large destruction of the chambers is caused by Wheatley's terrible handling of the facility. A main part of the map is the outside area, which is seen through the gaps and tears of the test, explosions are also common.

List of Wheatley-Themed Test Chambers


  • Textures - Black: Same as Clean, with black_wall_metal_006a-f.
  • Textures - White: Same as Clean, with checkered tiles (white_floor_tile_002b and white_floor_tile004b).
  • Checkered tiles are used on the floor\walls more often to point an important location (such as where to funnel, where the funnel ends, etc).




  • Appearance-wise, Wheatley appears to be a variant of GLaDOS' Intelligence Core (the one telling the cake recipe), with a blue "eye" and three dots, though Wheatley has dots only on his right side and possesses a white light as his iris instead.
  • Wheatley's Cockney accent heard in the Meet Wheatley video shown at E3 2010 uses a placeholder voice provided by Valve animator Richard Lord.[1] Due to very positive feedback, Valve considered at some point making the voice official.[2] Later Lord himself emphasized that his voice was temporary, saying that "theres no way you will be dissapointed with the final voice - i'm over the moon with who it might be." [sic],[3] until it was announced that Stephen Merchant would provide the final voice.[4]
  • During the 2011 Video Game Awards, Wheatley was nominated for "Character of the Year". He then made an appearance on the event which depicted him in space as he states that he would be even more honored for a space shuttle rescue.[5] Portal 2 then won the award for "Best Performance by a Human Male" with Stephen Merchant's portrayal of Wheatley.[6]
  • Wheatley makes a cameo appearance in an official plugin (Warning! May contain NSFW content), created by Bethesda and Valve, for The Elder Scrolls V: Skyrim, entitled Fall of the Space Core, Vol. 1. In it, he can be seen floating around the Skills menu.
  • In the developer commentary of Portal 2, it is revealed that he was originally intended to have tried escaping with other subjects prior to waking Chell up. This still remains in the game, as during the final boss battle, he says that he tried escaping with 6 people prior. However, due to his nature and the heat of the battle, it is unknown if he was lying or not.
  • When Wheatley speaks Spanish it translates to "You are using this translation software incorrectly. Please consult the manual."
  • Wheatley , alongside GLaDOS and Chell, appears in LEGO Dimensions; in the main story of the game, Wheatley attempts to aid the main characters Gandalf, Batman, and Wyldstyle obtain cake and later escape from a room-sized incinerator. Later, he reappears with the power of teleportation and again helps Chell overthrow GLaDOS by putting the Space Sphere in charge of the facility.
    • While non-canon to the Portal series, in his first LEGO appearance, Wheatley is still bound to railing (as he was in the early parts of Portal 2), whereas later he is free-floating; both he and GLaDOS reference the events of Portal 2's ending. This may imply that the two appearances are intended to take place at different points in time with regard to the Portal timeline.
  • When Wheatley is transferred into GLaDOS' body, his handles are removed. Oddly, when Wheatley is being sucked into space, the handles suddenly reappear despite still being connected to the main frame. This maybe an unintended story fault that the developers doesn't notice while developing the game
  • Wheatley's situational awareness is the same as his intelligence, very low. As shown when the duo wakes up GLaDOS in the Chapter 2, Cold Boot when Wheatley is "hacking" and doesn't notice GLaDOS is booting up, making the situation very comical or at least as you see in cartoons.
