|~ Cave Johnson about lemons|
It appears he 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 gaing immortality by uploding 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 making the AI we know as GLaDOS today. Its unknown how he managed to transfer his mind into the core from LEGO Dimensions.
- Although he doesn't physically appear in the first Portal game, his pictures can be seen on the walls with his face covered by companion cubes. His username CJohnson and password can be seen scrawled over the walls.
- Cave Johnson is also voiced by J. K. Simmons who always play as J. Jonah Jameson in Spiderman 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.
