Jak was the son of Damas, the former ruler of Haven City. At some point before the events of Jak II, he was kidnapped by Count Veger and subsequently lost. He was later found wandering around in the streets by Samos. Samos then placed him, along with his pet crocadog, into Kor's care. Later on, Samos planned to have Jak open the Tomb of Mar and retrieve the Precursor Stone, which could be used to stop the Metal Head's leader. However, the Tomb refused this due to his young age and Jak's older self completed them in his place.
Jak was then kidnapped by Kor, who intended on opening the Precursor Stone. After Kor's transformation into Metal Kor and his subsequent defeat, Jak and Samos were sent back in time to Sandover Village. Before leaving, he gave his older self the pendant around his neck. This pendant was the Seal of Mar, their ancestor.
After their arrival in the past, several years went by. Jak became the adopted nephew of a nameless explorer and Samos became the Green Sage. During this time, Jak befriended a boy named Daxter. As the two grew up, they went on many adventures together.
