WARNING: UNMARKED SPOILERS
The Tails Doll is a misunderstood soul locked up in the Companion Cube
because she figured he was dangerous (Like The Internet thinks he is). She said it
would never threaten to stab Chell as Self-Assurance.
Between both games, the Tails Doll broke out of the Cube and rigged GLaDOS
to come back to life if anyone other then Chell tried to escape. Namely, Wheatley
[Spoiler: At the end of Portal 2, GLaDOS
found him, trapped him in another Companion Cube and scorched it to make it look like the old one,
and gave it to Chell so it would kill her and whatever was left on Earth.
The Tails Doll breaks out of the Companion Cube and goes back down, has a massive battle
with the Turret Opera
, and is owned
Cue the Co-Op mode...
