Jak

Jak (birthname Mar) is the main protagonist in the Jak and Daxter series, being the titular and playable character in all of the games in the series (with the exception of the spin-off game Daxter). From his debut in Jak and Daxter: The Precursor Legacy, he has undergone many changes in his body - both internal and external - and matured into a fully grown man.

Before The Precursor Legacy
At the end of Jak II, Young Jak, and Young Samos (Samos), leave through the Rift Gate to the past Haven City (more specifically Dead Town), which an unknown amount of years previously was Sandover Village. This was where Jak grew up until his teenage years and where Samos Hagai grew to be an old wise sage of Green Eco. Jak was assumed to be raised by the Explorer, and at some point between the time traveling and TPL, he became friends with Daxter. The duo ended up on many dangerous adventures, the only one seriously elaborated upon being the last, in which Daxter became an Ottsel and thus set off the events of Jak and Daxter: The Precursor Legacy.

The Precursor Legacy
In The Precursor Legacy Jak gets Daxter into a mess of orange fur, and hair balls by accidentally pushing Daxter into a Dark Eco pool when he is pushed by an explosion used on a lurker. He then spends the rest of the game trying to gain enough Power Cells to make their way to Gol and Maia's Citadel, so they can change Daxter back to normal. Jak and the gang later (while at the Red Sage's hut) find out that Gol Acheron and his sister, Maia, are the evil duo that have been setting off Lurkers and trying to consume the world in Dark Eco. Jak then goes on to fight the duo in their Precursor Robot. Near the end of their battle Jak discovers Light Eco, which can change Daxter back or Defeat Gol and Maia and save the world. They choose to save the world. After the battle, Jak opens the ancient Precursor Door at the top of the citadel, and discovers the Rift Gate and Rift Rider behind it.

Daxter
Jak only appears four times, once at the intro scene where he is captured, once in the cage of a Prison Transport zoomer while being moved through the Industrial Section, once when Daxter was flipping through the channels in the Krimzon Guard Fortress, and once in the ending sequence when Daxter finished telling the story of how he saved Jak. In the intro scene, he has his appearance from TPL but has green hair. In the prison transport, he is wearing his prison outfit and his hair is shorter than it used to be. In the fortress, his hair has been grown to how it appears in the second game. In the ending scene, he has his Jak II appearance.

Jak II
Between the end of The Precursor Legacy and the start of Jak II, Jak, Keira, Daxter and Samos moved the Rift Rider and the Rift Gate back to Sandover Village, where they activated both and traveled to Haven City. There, Jak was captured by Erol, the commander of the Krimzon Guard, on behalf of Baron Praxis. Over the next two years, Jak was injected with Dark Eco under the Dark Warrior Program in an attempt to create a super soldier capable of turning the tide against the Metal Heads attacking Haven City. Rescued by Daxter before he could be executed, Jak vowed revenge on the Baron and devoted himself to bringing down Haven's leader using whatever means necessary.

Over the course of the game, Jak works for a variety of characters, including the Underground, a resistance movement against the Baron; Krew, a smuggler and crime lord; Onin, a seer found in the Bazaar; and Brutter, a Lurker who runs a Fish Cannery. It was eventually revealed that Haven City is the future of Jak's world, and that he was in fact the heir to the city. After defeating Metal Kor, Jak's younger self was sent back in time to grow up safely under Samos's watchfull eye.

Jak III
Soon after the end of Jak II, a war erupted in Haven's streets. Surviving Metal Heads and KG Death Bots battled the Freedom League for control of the city, ruining most of it in the process. Metal Heads took over the western area, the death bots colonized the industrial area. The Grand Council of Haven City declared Jak responsible for the conflict because of his friendship with Krew, and banished him to the Wasteland, where he was rescued by Damas and taken to Spargus. Throughout the game, Jak is sent on dangerous missions to gain the trust and respect of the people of Spargus and their king (Damas) and eventually makes it back to Haven City, accepting missions from many different characters as the war in Haven escalates and other threats appear. Cyber Errol was revealed to be the mastermind behind the KG Death Bots as well as the surviving Metal Heads, but the greater threat was from the incoming Dark Maker Ship, which Errol seeks to control in order to destroy the planet

In order to destroy the ship, Jak tries to activate the Planetary Defence System by accessing the Catacombs under the ruins of the Mar Memorial Stadium. Damas answered Jak's call for help, but was crushed under their vehicle when a blast overturned it, inadvertently revealing that he was Jak's father as he died. Jak continued through the Catacombs, activating the Planetary Defense System and traveling to the Dark Maker Ship to stop Cyber Errol, who escaped in a Terraformer before the ship was destroyed. Returning to the WasteLand, Jak defeated Errol and his Terraformer. The Precursors, revealed to be ottsels, asked him to come with them to protect the universe. He apparently turned down this offer, claiming that Daxter wouldn't last a second without him. It is also revealed that Jak's birth name was in fact Mar leaving gamers to speculate on whether Jak is the actual "Mar" who built Haven city, or if he is just of the same lineage and named after the famous figure.

Jak X: Combat Racing
Jak travels to Kras City with Ashelin, Torn, Samos, Keira and Daxter in order to attend a reading of Krew's will. Poisoned along with the rest of his friends and Rayn, Krew's daughter, Jak is forced to race in the Kras City Grand Championship in order to win the antidote. When he finally triumphs in the final race, the antidote is stolen by Mizo, forcing him to chase and defeat the crime lord to retrieve it. When Jak defeated Mizo they find out that Rayn had not been poisoned and that they had all been played.

The Lost Frontier
During The Lost Frontier, Jak accompanies Keira on her quest to become an Eco Sage. Despite not being able to transform into either Dark or Light Jak upon reaching The Brink, he is able to defeat Duke Skyheed and the ACS Behemoth, restoring power to the Eco Core and ending the worldwide Eco shortage. When he first saw Dark Daxter, he didn't look surprised.

Playstaion Move Heroes
Jak and Daxter are invited to the galactic hero games, along with Ratchet, Clank, Sly Cooper and Bentley. At first things seem just like a simple competition, but the heroes soon realize something is wrong. They find that the duo who brought them there are up to no good, and try to defeat the menace. Through the course of it, Jak seems to have a rivalry with Sly Cooper due to their differing styles (Jak being more rash and head-on and Sly being more cautious and recon) causing arguments which are subsequently broken up by Ratchet. Though they eventually part on good terms.

PlayStation All-Stars Battle Royale
Jak, with Daxter on his shoulder, appears as a playable character in the fighting game. His moveset consists of various gun mods seen in Jak 3, as well as a few attacks from Daxter. He is given three "super attacks", which are the basis for victory in each match. His standard super is named "Precursor Legacy", in which Jak gathers blue eco from a blue eco vent and uses it to K'O opponents. In his level 2 super, Jak turns into Dark Jak and uses his signature Dark Bomb attack. He transforms into Light Jak for his strongest super, and is able to access all of his various Light Eco powers, except Light Regeneration. This game also marks Jak and Daxter's first appearance on the PlayStation Vita.

In Jak's story mode, he and Daxter have set out to find more Eco (meaning that it possibly takes place before The Lost Frontier), they fight their way through other competitors for the 'Eco' (actually a substance called AP) when they run into Ratchet & Clank, Daxter insults them which leads to a battle, Jak wins and moves on to fight Polygon Man. After defeating Polygon Man, Jak and Daxter obtains the new eco and returns home to see Keira and Tess.

Personality
Jak evolves drastically as a character over the course of the series. During The Precursor Legacy, he is presented as brave and curious, willing to throw himself into dangerous situations. In Jak II, after being subjected to Dark Eco treatments for two years at the hands of Baron Praxis, revenge is his main motive, and he has become angry and reckless - this is only exacerbated by the presence of the Dark Eco in his system. He also takes some enjoyment in killing Metal Heads and a fondness for guns. Nonetheless, Jak does retain some heroic personality traits. Jak 3, which sees him gain Light Eco powers to balance the Dark Eco, sees him become less angry and more mature; this was almost certainly aided by the death of his father. Jak X shows him has having relaxed somewhat (due to the balancing effect of Light Eco), though this final encounter with Mizo shows that the anger still exists under the calmer exterior. In TLF, he seems to be more carefree and happy. Despite some scenes hinting his anger (i.e. when he tries to turn to Dark Jak, seeing the Dark Warrior Program chair, etc.) he seems to be more cheerful, particularly around the time he finds out about Dark Daxter, and more like his old self from TPL.

Appearance
Jak's appearance varies over the course of the series; however, his outfits maintained the basic pattern of blue shirt/jacket and beige trousers. The armor on his left shoulder has remained in every game: presumably, this protects him from Daxter's claws. He has a lean and muscular build, as well as yellow-green hair and cerulean blue eyes. He has long and pointy ears, just like an elf. He wears a pair of goggles in every game too. He also has a metallic ring strapped to his chest, which remains here for all of the games excluding Jak X: Combat Racing, which is replaced by a similar strap.

The most noticeable change in Jak's appearance from game to game is often his hair, which has ranged from spiky and long to short and rough. Plus the appearance of his goatee as you can see in Jak II and a possible mustache and beard which can be toggled in The Lost Frontier. He gets taller in each game (In TPL he's 5'6, in Jak II he's 5'8", in Jak 3 he's 5'9" and in Jak X: Combat Racing he is 5'10". It is unknown whether or not he is any taller in TLF), and gains slightly more muscle tone throughout the series, more noticeable upper body muscle.

Whilst in Dark Jak mode, Jak's hair becomes grey, his skin also becomes grey except the blu-ish tint to his skin. He also grows horns (which disappear due to the Light Eco affecting him in Jak 3) and claws. Also Dark Eco in its lightning form streaks from his body. In Light Jak mode he gains an ominous blue-ish glow, whilst the majority of his body turns a glowing blue colour. He also gains wings (if used). His eyes also become a pure white. It is worth noting that while "channeling" Light Eco, like in The Precursor Legacy, he simply becomes a pure glowing silvery white color.

Romantic Interests
Throughout the series Jak has only 2 romantic interests, although one is more common than the other. Keira is the most common romantic interest throughout the series. Right from the opening sequence of Jak and Daxter: The Precursor Legacy they obviously have feelings for each other, as Keira calls him a "brave adventurer" and Jak blushes. These small things continue right through TPL until the end where they lean in to a kiss but Daxter interrupts them. At the very start of Jak II they have a small bit of back and forth but get separated through the rift gate. Keira becomes a race mechanic who is hidden by a curtain and as only Jak talks to her she does not realize it is them. Jak attempts to flirt with "the mechanic" but she tells them to go away. Later Daxter talks and Keira recognizes his voice and realizes its them. When Ashelin is around, Keira calls herself "Jak's very good friend". She and Jak have an argument about Keira thinking Erol is a good racer and Jak working with Krew. Things remain awkward for a short time but they make up. At the end of Jak II they again lean into a kiss but again Daxter interrupts. They flirt outwardly throughout Jak X and at the end for the third time they lean in to a kiss but this time Daxter interrupts and says "Will you kiss her already?" Keira pulls Jak into a kiss. They do not appear to have an outward relationship in TLF but they obviously care about each other still as Jak is protective when Phoenix flirts and at one time given the choice Keira chooses Jak's opinion over Phoenix's. At the end they kiss again and plan to go over the brink together.

During Jak II Jak's 2nd love interest forms. Ashelin, the Baron's daughter is helped twice by Jak and then appears to have an interest in Jak, however Jak does not appear to share these same feelings, but Keira gets protective at one point and obviously does not like the fact that Ashelin is interested in Jak. During Jak 3 Ashelin does not try to hide how much she wants Jak back in the city and how sorry she was he was forced to leave. At the end of Jak 3 they have an offscreen passionate kiss but they obviously do not share this fact for they are both still in their relationships in Jak X: Combat Racing. In Jak X: Combat Racing they no longer appear to be in a romantic state, and Jak kisses Keira at the end. But from Jak 3 onwards, Torn and Ashelin look like they might be interested in each other, but their hard ways hide it. In Jak X it becomes more apparent. In Jak 3 there is one secret you have to unlock and it is the Jak 3 model viewer. If you put it on Ashelin she admitted that she likes Jak.

Abilities
Jak's primary ability is his ability to channel various kinds of Eco, which is used to great effect in The Precursor Legacy. Jak II saw him gain the ability to transform into Dark Jak due to the two years of Dark Eco experimentations performed on him at the hands of Baron Praxis. In Jak 3, he was granted Light Eco powers by the Precursors, allowing him to transform into Light Jak and balancing the destructive influence of the Dark Eco already in his system. In Jak and Daxter: The Lost Frontier, Jak gains multiple eco powers from special Precursor Idols and can also purchase powers from Keira using Dark Eco.

He can't generate Eco (as that would mean it would recover over time), instead he absorbs it into himself, which he stores until he uses it to fuel his abilities until it either runs out or he stops using it, once he absorb all that he can, he can't absorb any more until he uses some or all of it up, his use of it varies, In TPL he can only use it for a short amount of time before it runs out. The more he picks up, the longer he can use it. In Jak II (either due to him maturing by 2 years or via the Dark Eco Infusions), he can store Dark Eco inside him, which he can use to turn into Dark Jak until it runs out (although to unlock most of his abilities, he needed the help of the Oracle in the Water Slums). In Jak 3, he can store more Dark Eco (and later Light Eco) than he could in Jak II (whether this was due to the Eco Crystals or he has been working on further controlling his Eco Powers between game, it is uncertain) and can choose when to stop using them and even change into Dark Jak and Light Jak forms regardless of how much of either Eco he has absorbed (although with much less use of the abilities of each form). In Jak and Daxter: The Lost Frontier, he is able to use Green, Red, Yellow and Blue Eco powers via smaller Oracle statues, which recharge over time, the reason for why he is now able to recharge his Eco reserves without absorbing it directly (it's possible that due to the Eco storms, he is constantly absorbing it, which is another explanation why it's dangerous to change forms in that game).

Other than this, Jak is also shown to have be athletic and acrobatic with much physical prowess. He can punch, spin kick, and even head dive hands-first to break most objects. If not enough, he can even leap from a rolling position to not only reach far distances, but can even plow into foes. He can also high jump from a crouching vault and even uppercut up the same height. Even with holding a gun in both hands he can still jump as high with only his legs from a normal crouching position. Another notable trick is that during the hand dive, Jak can bounce off from the force of the attack to bounce great heights, implying good upper body strength.

Jak is also a skilled racer, and races often features as prominent plot points in the series. It is also thought he can also activate precursor artifacts since in The Precursor Legacy when Daxter was holding the artifact did nothing but when passed to Jak it started to glow or when he activated the Rift Rider.

Equipment
Extra equipment is not seen in The Precursor Legacy; it was in Jak II, when Jak acquires the Morph Gun, that the games began to feature extra equipment. The Morph Gun is also seen in Jak 3; however, it is replaced by the Gunstaff in The Lost Frontier.
 * The Titan Suit, and its derivative, the Dark Maker Bot are used in Jak II and Jak 3, respectively.
 * During Jak II, you receive the Jet Board from Keira. The Jet Board is also used in Jak 3.
 * During Jak 3, you collect pieces of Mar's Armor which increase his health with each new piece that Jak obtains.
