Portal's Companion Cube is perhaps one of gaming's most memorable and lovable characters (items?). But is the Companion Cube another cruel test set up by GLaDOS? What sinister secret is hidden behind the Companion Cube's cute pink hearts? Like most other things in Portal, the cube may be more than meets the eye...

I HATE YOU AT THE END I SMASHED MY HEAD IN MY PHONE BECAUSE YOU SAID TO IF I WANTED TO WATCH ANOTHER VIDEO AND I DISLIKE
I miss the goofy, obscure trivia of OldPat's theories. The lore videos were neat at first, bit after like 4 years of nothing but that, it's lost the appeal

I have played P1 and P2 and dont recall loving the companion cube or attributing any sentient qualities to it . . . . . . I apparently dont have issues.

Dose anyone remember this intro
In the game "Terraria" a NPC called "Travelling Merchant" can sell a item called "Companion Cube" for 5 Platinum Coins, if you stay in lava with the cube for some seconds the cube will make a scream sound, some persons say the scream is the sound the boss "Lunatic Cultist" makes when you kill the boss, The Official Terraria Wiki says that when you and the cube are in total darkness the cube will "stab" you, dealing 3 damage. and the death message will be "[Name of Player] was stabbed" . . .

matpat should do remakes of all his old ones. because watching this in 2019 is a step down from his usual quality. Ah the old days

There was nothing inside the cube. If there was a full body, it would have uneven weight. If the body was chopped up to distribute the weight evenly, then it couldn't possibly talk. Fratricide could also be a reference to the fact that both Chell and the Cube were things made by Aperture as Chell is only a test subject for GLaDOS, thus making them "siblings".

Also I know im late but there is more evedence in terraria. When you get the companian cube pet and dip it in lava, it will let out a loud scream. Edit: What I think is that the cube is alive. When glados says they cannot talk there is proof she is lying :P

Rodrigo Costa (18 days ago)
you are wrong because 1- the fraticide quest is because you trat you cube like a brother 2- is implossible that they have people inside because in portal2 if you take the cube to the elevator the cube is destroyed 3- in the comic the rat is sick an the cube is an alucination

I have a little bit of extra evidence for this. At the end of portal 2 once you escape glados say "don't come back" once your outside the door shuts then opened and throws out the companion cube out then the door shuts against it throws the cube out because it doesn't want a dead YOU back.

If the companion cube is a person then how is Glados able to actually disintegrate it
darquedragonfyr e (26 days ago)
I think the reason you get the achievement fratricide is because the companion cube was supposed to be your companion

The ending of portal 2’s co-op portion proves this theory wrong when they are scanning test subjects and no skeletons or biochemical matter comes up when companion cubes are scanned on accident

I'm curious... Like so Matt can see. At the end of Portal Two GLaDOS sends Chell above ground in a field and then throws a companion cube with her. Now, perhaps its just your first companion cube and GLaDOS felt like giving you that memory. OR.... when you stop to consider that humans are inside the cubes, who is inside the cube sent up to the player's character? Could it be Caroline? GLaDOS's way of leaving a memento? Or perhaps Chell's parents? Therefore following through with her promise. I mean, the achievement for throwing your first cube into the fire was titled "fratricide." and the cube that spews up at the conclusion of the second game has burn marks all over it.
