The '''Weighted Companion Cube''' (often referred to as the '''Companion Cube''') is a recurring object in the ''Portal'' universe. It appears almost identical to the [[Weighted Storage Cube]] but with a pink heart replacing the [[Aperture Science]] logo.

In ''[[Portal]]'', the Companion Cube was given to [[Chell]] in order to aid her in completing [[Portal Test Chamber 17|Test Chamber 17]]. {{Spoiler text|In order to progress through the exit at the end of the chamber, the cube was dropped into the [[Emergency Intelligence Incinerator|incinerator]] to be "euthanized". [[GLaDOS]] used this moment to taunt Chell during their confrontation. However, the Companion Cube can be seen prior to the end credits next to the [[Cake]], suggesting that it survived.}}

The Companion Cube makes a prominent appearance in the ''[[Portal 2: Lab Rat]]'' comic, in which it speaks with protagonist [[Doug Rattmann]]. This appears to reference ''Portal'', in which GLaDOS states that the Companion Cube cannot speak and, if it does, its advice should be [[Media:GLaDOS_13_part1_middle-2b-2.wav|disregarded]].

In ''[[Portal 2]]'', {{Spoiler|GLaDOS briefly torments Chell by repeatedly destroying Companion Cubes in [[Portal 2 Chapter 2 Test Chamber 7|Test Chamber 7]]. It is at this point that GLaDOS claims that the Cubes are in fact [[Media:GLaDOS_sp_a2_pit_flings06.wav|sentient]], which suggests that they possess some level or rudimentary intelligence similarly to [[Turrets]]. The Cube also makes an appearance in the [[Co-op]] campaign but is inaccessible, preventing the player from interacting with it. After Chell leaves the facility upon completing Portal 2, a scorched Companion Cube is ejected after her. This Cube is not the newly-designed Portal 2 Companion Cube, but is the same as the cube from ''Portal''. Valve said that it's the exact same cube the player euthanized in the first ''Portal'', that is given back to the her <ref>[http://www.rockpapershotgun.com/2011/04/27/valve-on-portal-2-spoiler-interview-part-one/ Valve On Portal 2: Spoiler Interview Part One] on [http://www.rockpapershotgun.com/ Rock Paper Shotgun]</ref> .<br> The Companion Cube in ''Portal 2'' hums an excerpt of [[Turret Opera|Cara Mia]], which can be heard when it is nearby.}}
