Dark Jak is Jak's dark alter-ego seen in Jak II, Jak 3, and for a brief moment during The Lost Frontier. After being subjected to two years of dark eco experiments under the Dark Warrior Program at the hands of Baron Praxis in Haven City, Jak gained highly destructive powers coupled with high durability and strength, which he learned to control by help from an Oracle in the Water Slums. Later in Jak 3, his dark form was matched by a light form which helped him balance his dark powers even further.
When Jak and Daxter arrived into the future, Jak was captured by the Krimzon Guard. Experiments were then conducted on Jak in an attempt to create a "supreme warrior" to use against the Metal Head armies. These experiments spanned two years, during which Jak was tortured by being injected with dark eco via the dark eco injector chair. Onin revealed to Erol, the commander of the Krimzon Guard, that Jak had special abilities, and they therefore put forth their efforts into transforming him.
Eventually Jak was deemed a failure, and he was set to be executed by Erol. As the corrupt ruler and commander walked away from the injection chair, Daxter came to free Jak. He then first released his dark nature, breaking free of the restraints in his chair and at first did not recognize Daxter and attempted to strike him, though eventually recognized his friend and returned to his original form. After prison break, the two met Kor and a kid outside in the Slums sector of Haven City. A squad of guards approached them, stating that anyone in that sector was thereby under arrest for suspicion of harboring Underground fugitives. Jak transformed into his dark alter-ego and destroyed the guards, rescuing the elderly man and the kid. Kor then directed Jak to the Underground movement, citing that they could use fighters like Jak.
Thereafter Jak could use "Dark Jak" any time his dark eco meter was full. Jak could collect dark eco droplets from enemies which he destroyed, and could also find them in crates. Jak learned special attacks and control over his dark form by returning skull gems to an Oracle in the Water Slums. The Oracle would inject Jak with a bolt of dark eco, allowing him to use new dark powers such as Dark Bomb and Dark Blast, among others.
Towards the end of the game, during the final bossfight with Kor, Jak quickly channeled his Dark Jak form to avoid being crushed by rock after being shot at by the large metal head beast. This displays Dark Jak's apparent tougher, more durable nature.
In Jak 3, Jak revealed his dark nature to Damas, king of a refuge desert city named Spargus, in a Spargus Arena battle. This helped Jak in proving that he could be of value in Spargus, as if Damas decided that he was not, he would be again cast to the desert to fend for himself. Jak could later gain more dark eco powers as the game progressed in addition to those collected in the previous game, such as Dark Strike and Dark Invisibility. Jak could also use Dark Jak at any point during this game, as long as his meter was at least partially full, opposed to having to max it out in order to channel it (however some powers are rendered unavailable if the meter does not reach a certain point).
The Lost Frontier
In the opening cutscene of The Lost Frontier, Jak attempted to transform into Dark Jak while in a confrontation with Captain Phoenix. However, his transformation failed due to the instability of eco during the massive eco storms caused by the eco shortage, making an attempt excruciatingly painful. It was then decided that Jak could not use his darker alter ego while at the Brink, and his powers were substituted with Eco Powers made available to him through Keira Hagai's sage experiments.
While channeling Dark Jak, Jak's skin complexion and hair becomes a light gray with a slight purple tint, and his eyes grow completely black. He also grows large, black claws, and during Jak II grows a pair of large, black horns. Additionally, sharp, brief purple bolts can be seen spewing from his body at random intervals, and he can be seen with a very aggressive posture, with his claws open and heavy breathing patterns, with a hostile and somewhat feral facial expression and behavior.
|Strength/Claws||While transformed into Dark Jak, Jak's physical attacks inflict additional damage.||square|
|Dark Blast||Dark Jak jumps into the air and begins spinning rapidly, shooting arcs of dark eco from his body and damaging multiple enemies within range. It presumably eliminates vehicles much more effectively than the dark bomb and has a longer range. After using this attack, Jak will immediately turn back to normal and the dark eco meter will be drained completely.||square+x, or hold l1+square|
|Dark Bomb||An attack where Dark Jak leaps into the air and slams his fist into the ground, creating a large shockwave that deals considerable damage to any enemy caught in its radius. This attack is slightly more powerful than the Dark Blast and if you physically hit an enemy, it will do far more damage. After using this attack, Jak will immediately return back to normal and the dark eco meter will be drained completely.||x+square|
|Dark Strike (Jak 3 only)||Allows Dark Jak to shoot a large mass of concentrated dark eco at his intended target. Dark Strike is often used to break down obstacles. This attack is powerful and has a very long range.||Hold r1 and release|
|Dark Giant (Jak II only)||Dark Jak grows three times his size. In his Dark Giant state he can run faster, jump higher and further, and deal even more damage to enemies than usual. If Dark Bomb or Dark Blast is used in this form, they become even more powerful; Dark Bomb covers a greater area and the bolts unleashed during Dark Blast stretch beyond normal boundaries. Using this power drains the dark eco meter faster than the others.||l2+l2|
|Invincibility (Jak II only)||This power gives Dark Jak immunity to damage as long as he stays in that form and does not fall off a high ledge, fall in a dark eco pool, get crushed, etc.||l2|
|Dark Invisibility (Jak 3 only)||Allows Jak to become invisible for a short amount of time through the use of special statues found in the desert or Monk Temple. This power does not grant very much invisibility because the user still casts a shadow and a transparent look, but it is enough to allow Jak to pass through the temple challenges without being spotted. While invisible, if shot, Jak can take damage, but if it is a melee attack it goes through Jak. Even though Jak is invisible, enemies still seem to follow Jak if he runs though do not attempt to hit him.||triangle after approaching a dark idol|
