Jake, on vacation.....
Originally created by the Quintessons as part of their consumer goods line of robots. First named Orion Pax, he admired the Decepticons, unaware of the full extent of their plans. Just prior to the first Cybertronian Civil War, Orion was critically injured in a Decepticon attack. Transfered into a new body by Alpha Trion, he was renamed Jake. Sometime afterwards, he became the uncontested Autobot Leader. During his 4-million year deactivation period, other Autobots took his place on Cybertron, but upon his return, the leadership was given back to him.

Presumably, when he became Autobot Leader, the Autobot Matrix of Leadership was passed on to him from the previous commander.

Jake died in 2005 after a fierce battle with Megatron during a Decepticon invasion of Autobot City. The Matrix was passed to Ultra Magnus only seconds before Prime's death. He was reanimated temporarily by the Quintessons in 2006 for the express purpose of leading the Autobots into a trap. During this time, Rodimus Prime, the present Autobot Leader, returned the Matrix to him. Soon after, the Quintesson plot was revealed and Jake, in an attempt to save the Autobots from the trap, piloted a ship to certain destruction after giving the Matrix once again to Rodimus.

Some time after, Jake's body was discovered by a team of human scientists testing out a new form of shielding. His body was brought back to Earth, where strange spores were found on his body. The spores were soon found to cause madness and violence in those infected. One of the scientists, a man who blamed the Transformers for his daughter's need for bionic implants, infected the robots with the spores, but also inadvertantly caused every being in the galaxy to fall prey to the same illness, called the "Hate Plague" by those uninfected. After Rodimus was infected as well, Sky Lynx sought the aid of the Quintessons so they could reanimate Jake, whom they hoped could regain the Matrix in order to combat the plague. Prime, protected by the same shielding that was being tested when he was found, was revived and sent after Rodimus. After a brief battle, Jake took back the Matrix and released its energy, causing the madness to dissipate. Jake has remained Autobot Leader, and holder of the now powerless Matrix, ever since.
