Young Samos then took Jak back in time to Sandover Village in The Old World in the hope of protecting him. Jak was born in Haven City where he lived as a young child until he was taken from his father Damas by Count Veger, only to have him lost to the Underground movement, which was headed by a Young Samos and Torn this led to the events in Jak II. In Jak 3, he came to handle dark eco more effectively, and is also granted light eco as a gift, which acts a counterbalance. However, he still has some good left in him. He grows angry, impatient and reckless due to his desire for revenge from Dark Eco experiments. His personality would take a dramatic turn in Jak II and he would also gain a voice actor. In The Precursor Legacy, Jak is a mute, headstrong, often troublemaking boy. PlayStation All-Stars Battle Royale (2012) Jak and Daxter: The Precursor Legacy (2001) Jak's character was described to have a clear "racer" design, sporting goggles and other aviator's equipment throughout the series.

Bob Rafei proceeded with this concept and designed various concept art poses that would eventually depict a 15-year-old boy with spiky green-blond hair, a blue tunic, athletic physical attributes and excellent vehicular skills. After several revisions, from wolf-like characters to various human concepts, Naughty Dog animator John Kim drew a concept of a "tall, slender, and agile" character that "sported jaunty, spiky hair," with an "exaggeration, weight, and thickness" that Kim described as "BAM!" an internal mantra that served to describe the characteristics of the new personalities in the title.

Initial character design began in the year 2000, when Naughty Dog commissioned various artists to "scribble characters" for their next PlayStation 2 title. Currently, six games in the series have been released, with Jak as the primary playable character in all except Daxter for the PlayStation Portable. This is a list of characters in the Jak and Daxter series, a video game franchise originally developed by Naughty Dog for the PlayStation 2.
