Jak and Daxter's arrival to Haven City was a little bit "different" then they had expected. Jak was taken to prison by The Krimzon Guards, who unfortunately knocked him out as they took him. Jak was taken to the prison where they did about a dozen of experiments on him with large amounts of dark eco, causing things to change in Jak's body making in to a monster. He was in prison for two long years, Erol and The Baron decided this "experiment" was a failure. After leaving him alone, a light of hope came along as Daxter came on an elevator to save Jak. After Jak almost killing Daxter by mistake, He finally talks for once after returning to normal. At first, Daxter had to get use to the fact that his best friend had been poisoned. Daxter got comfortable in a few days as they made themselves home in the walls of the city. Once outside the prison, they meet an old man named Kor, and the Kid, a young child who resembles Jak and, fittingly, does not speak. Jak saves them from an approaching group of Krimzon Guards and, for the first time in public, transforms into Dark Jak. Kor is convinced that Jak could save the city. He advises them to see "The Shadow" who is the leader of the Underground. After meeting Torn, the highest rank man of the Underground, he sends the "Demolition Duo" to the Hip Hog Saloon. And this friends, is where the story shall begin. Jak and Daxter will be meeting people who will become big parts of their lives. And she would be standing right under his nose.
