|~ Cave Johnson's infamous rant about lemons.|
Cave Johnson is a major character in the 2011 popular video game Portal 2 and (by extension) Portal, and the posthumous Greater-Scope antagonist of the franchise. Although he only appeared in video diaries, his eccentric and narcissistic personality makes him one of the important characters of the series as his actions lead to GLaDOS being created.
Cave does not physically appear in the first Portal game. However, pictures of him can be seen on the walls of Ratman's Dens with his face covered by images of Companion Cubes. His username CJohnson and password can also be seen scrawled over the walls.
More about Cave Johnson and his past is revealed after Wheatley's betrayal. It appears Cave was a natural leader who could easily put people at ease despite the fact more often then not his experiments were highly dangerous. After being exposed to moon dust his body started to shut down. Realizing he was going to die in the near future he put all of his efforts in gaining immortality by uploading his mind into a super computer. As a precaution should he die before the system was ready, he asked that Caroline's mind be uploaded in his place. As he died before the the system was complete Caroline was uploaded into the computer which created the AI know as GLaDOS.
A special stage in LEGO Dimensions reveals that Cave Johnson succeeded in transferring his mind to a computer, by placing his conscience in the body of a core that has been locked in old Aperture Science, he claims that "Being the genius I am, I managed to get myself in to a shiny core body and I've been locked in here ever since". It is unknown how he managed to transfer his mind into the core.
- Cave Johnson was voiced by J. K. Simmons, who also portrayed J. Jonah Jameson in Spider-Man films.
- While Cave Johnson was shown to have somehow transferred himself into a core in LEGO Dimensions, the events that happened in the game are considered non-canon to the Portal series of games.
- Since his actions led to GLaDOS being created, that could make him the Bigger Bad of the franchise (though it is possible that he never intended for GLaDOS to turn evil).
