He was voiced by J.K. Simmons in the final project.

Biography

In the original scripts of Portal 2, Cave Johnson was intended to have a different role. He at first was envisioned to be the protagonist, but this idea was scrapped. He was described as "being trapped in a computer" while controlled by the player.

Later, he was intended to be the main antagonist of the story line. He would initially serve as a sidekick to the player, but would eventually betray them, and confront them for their "crimes against their brothers-in-arms". He would also go mad with power and lose touch with reality. The archetype of this character would later be given to Wheatley. This idea however was scrapped in favor of a sequel, which published Cave Johnson as a posthumous character who served as comic relief.

Trivia

  • During the Perpetual Testing Initiative DLC for Portal 2, which sees the protagonist Bendy travel across a multiverse, there is universe that depicts a similar scenario in which Cave was successful in uploading his mind into a computer (in this case, Glados) and eventually becomes corrupted with power. However, it is unknown if this was intended to be a nod to the original draft of the plot for Portal 2.
