Little is known about Gabe Jonson's past, other than that he was brothers with Cave Jonson and a student of Portal High School and came to be friends with the TEEN FORTRESS 2. Though, since the evil clones of the TEEN FORTRESS 2 refer to Cave as their leader, it is possible that Gabe is the leader of the good TEEN FORTRESS 2.
He first had an idea about portals after hearing about Robot and Roslalonde Lettuce. When he hears that a portal machine killed them, instead of a portal machine Gabe decides to build a portal gun.
When his girlfriend Caroline was shot by Cave, Gabe, in outrage, kicked Cave so hard he exploded. As Caroline died, Gabe decided to build a robot body for her, named GLaDOS after her mother Principal GLaDOS. For a while, Gabe and GLaDOS lived together, even after Assirram Strebor installed a virus into GLaDOS, making it evil.
About 13 years later, Gabe, now named Cave, had founded a shower curtain company Aperture Science, but didn't quite like it as he wanted to own the brand of Portal High School. As such, he and GLaDOS took over Portal High School and established Portal Labs. Gabe and GLaDOS also became the parents of two girls, Chell and Marrissa Roberts, via artificial insemination, but, due to a mishap, Ratman's DNA was sampled for Chell instead of Gabe's, making Ratman Chell's biological father.
Gabe died in AG 2041, after a mishap with one of his inventions, namely the three colors of paint. As such, first in ITS MY LIFE! he appears in Andord Hell. He immediately recognizes Chell and Marrissa as daughters, and becomes their friend.
Gabe's Andord Hell self is later killed by Marrissa, when she misuses her powers against GLaDOS. Chronologically, Gabe is not seen afterwards, but it is implied that he was resurrected by Wheatly's spell in the end of THE MARRISSA GAMES, as he appears, alive and well, in Marrissaverse Stories 2015.
- The reference to Gabe Newell was not intended by Doombly; rather, he played Portal 2 without subtitles, as he finds them distracting, and actually thought Cave Johnson was named "Gabe" at first.
