That's it, I give up on finding Jason's app. I'll remake it.
Name: Jason Brody
Game of Origin: Far Cry 3
Appearance:

Morality: Semi-Chaotic Good
Weapons: Whatever he feels like pulling out of his ass.
Abilities: A skilled athlete, Jason proves himself numerous times throughout the game to be able to perform many physically demanding actions, such as sprinting and swimming for extended periods of time, skydiving, para-sailing, mountain climbing and snowboarding. He has exceptional upper body strength, and is able to climb ledges and hang from ziplines by one arm. Jason is a naturally talented firearms user, as mentioned by the flashback of Grant in Mushrooms in the Deep. As the game develops, his firearm skills develop further, and he also becomes a skilled archer. It is likely that Jason learned these skills from Grant who was an Army Reservist. Although perhaps not an expert, Jason develops some skills with explosives throughout the game, as he is seen using C4 explosives in numerous levels and also learns how to effectively use grenades.
Jason becomes a skilled melee fighter during the course of the game, as shown by his fights and victories over Hoyt, Vaas, and Buck, all of which had seemingly more combat experience than him (Vaas was formerly a Rakyat member and most likely an experienced fighter, and Buck served in the military). His skills as a melee fighter also make him an excellent assassin. Later in the game, he is capable of chaining multiple kills together and being able to perform aerial and ledge kills. Jason also becomes an experienced craftsman, hunter and herbalist, making all of his equipment from animals he hunts himself and being able to create a variety of medicines with differing effects as he gains experience.
Jason was given the Tatau by the Rakyat, a mystical tattoo which represents three totemic animals (Heron, Shark and Spider). The Tatau allows Jason to tap into his "warrior" nature and form a connection of some kind with the jungle of Rook Island. When Jason upgrades his abilities, the Tatau actually grows in size and complexity to reflect the totems that he is drawing upon. This tattoo likely explains how Jason rapidly changes from a terrified, ordinary young man with an adventurous streak to a deadly fighter. The Tatau's exact abilities are listed below, and explain why Jason has the edge over his opponents:
Enhanced Strength: The Tatau gives the user enhanced strength which make them stronger than the average adult. With this, Jason can lift heavy objects and exert himself for longer. As the Tatau grows, so does the increase in his strength.
Enhanced Speed: Jason has enhanced speed, which allows him to move very fast for a greatly increased length of time (hence the Tatau ability gained later in the game.) With this, Jason can possibly match even an olympic athlete.
Enhanced Reflexes: Jason has demonstrated on numerous occasions that his reflexes far outmatch others. Jason is even superior to warriors such as Vaas and Hoyt, even when the former had been involved with the Tatau, and as such has similar abilities to Jason, namely because of the latter's large Tatau.
Enhanced Intelligence, Cunning and Bloodlust: Jason, although not stupid before, gained great knowledge of how to assault enemy bases and general cunning. However, his willingness to fight was also amplified. These abilities do not increase with the length of his Tatau.
Personality: Before the events of Far Cry 3, Jason was originally an ordinary and immature slacker who lacks confidence. Now on the island, Jason develops into a brave, adventurous, smart, confident and dangerous idividual, but also disturbed, violent, and unstable. Jason's sociopathic traits become more obvious as the story progressess, with Jason quick to accepting the violence around him and even quicker to getting involved in killing, eventually admitting to Daisy that he found killing fun and felt like "winning". Despite that, Jason can be rather humorous and immature at times such as being excited when burning the weed field or causing mayhem towards his enemies. Jason is very cultured, using popular and famous references during his adventures such as "leap of faith" and "Use the force!" and also 'Would you kindly activate?' Jason is also very caring, protective and loyal to his family and friends, where his primary motives at the island are to rescue them. There is some evidence of his loyalty, such as swearing revenge to kill those who harm his family and friends (specifically Vaas for kidnapping the group and murdering Grant, Buck for raping and torturing Keith for his own pleasure, and Hoyt for shooting Riley and keeping him prisoner). Ever since Jason barely escaped Vaas's camp, he grew to become a famous hero amongst the island's residents, though he does not seem to care about his status. During his adventures, Jason would lend a hand to the residents.
Biography: Born on December 30th, 1987 in Los Angeles, California; Jason is the middle child of three siblings, Grant and Riley. In his early years, Jason was a skilled athlete and participated in events. At some point in his life, he meets Liza Snow and falls in love with her. After Riley earns his pilot license, Jason and his friends began to celebrate in Thailand. While partying at a nightclub, Jason's relationship with Liza begins to strain, mainly because of his party-focused lifestyle and immature personality. Also, Jason, Keith and Riley have a fight with a group of patrons which causes them to flee. At that time, the friends meet Doug, the nightclub DJ who convinces them to go to an "island where [they] can do anything...". What Jason and his friends do not know is that Doug is actually a spotter for Vaas Montenegro, the insane pirate leader.
As soon as Jason and his friends land on the Rook Islands, their whole lives change, leading to the events of Far Cry 3.
