Son of Alan Bradley and Lora Baines-Bradley, digitized unwillingly by Ma3a to stop the infection of ENCOM.
Action Survivor: He's not as gifted as the Flynns when it comes to an Indy Ploy, but makes up for it by figuring out how to use the weaponry.
Brilliant, but Lazy: Jet got arrested for hacking into his school's mainframe because he was "just bored," got an "A" in his computer classes (with three other classes getting incompletes), and turned down a promotion in order to continue being a game designer. His father is less than thrilled.
Decomposite Character: In-game, he's very much a prototype for Sam Flynn, with the playful hacking, the arrest record, and apparent apathy. In the comics, he seems more a prototype for Beck, being a Hero with Bad Publicity, leading an uprising inside the system, and the troubled relationship with his father-figure.
Did Not Get the Girl - At the end, Jet goes back to the analog world, and Mercury has to stay in her digital one.
Mercury:You're leaving, aren't you? This is no world for a User. We're too crude and rudimentary.
Jet:If anyone's crude, it's us. We're not ready to exist here; not yet, anyway.
Former Teen Rebel: While he's implied to have had a stormy adolescence, complete with bad grades and an arrest record, Jet appears to have cleaned up his act by the time the story opens. While his job isn't the one his father would like him to have, he is holding down employment and paying his bills. His boss even assures Alan via email that Jet more than pulls his weight on the job, and promoted him to lead programmer.
Kidnapped By The Call: Ma3a didn't warn him, much less ask for consent. Before he fully understands what's going on, he's digitized, has a disc shoved in his hands, and fighting for his life.
Missing Mom: In-game emails and a flashback reveal that Lora died in a lab accident. This has driven a wedge the size of Texas between Jet and Alan.
Only Known by Their Nickname: You only learn his "legal" name from an in-game email. In the spin-off comic, he insists that even the psychiatrist call him "Jet."
Playful Hacker: He cheerfully says that there isn't a firewall he can't take down. Again, his father (who, as you recall, programmed one of the most Badass security programs ever made) is less than thrilled.
Jet:Don't worry, Dad. There isn't a firewall I can't take down.
Alan: (sarcastically) Yes, I almost forgot about your "alternative" set of skills.
Right Man in the Wrong Place: He ran down to the lab because he heard the F-Con goons kidnap his father - only to have Ma3a activate the laser.
Ma3a: (in response to Jet's question about why she digitized him) My existance was threatened by the spread of the corruption...Alan-1 was not available. [Jet] was.'
Robosexual: It doesn't matter to him that Mercury is software.
Shell-Shocked Veteran: In the Ghost in the Machine spin-off comic, we see that the Fridge Horror of cyberspace hit Jet like a speeding truck. Not only were the Programs he killed sentient beings, but he possibly killed some digitized humans as well.
(Ma3a for short). Holder of the digitization correction algorithms.
Benevolent A.I.: Despite kidnapping Jet out of desperation, she turns out to be a loyal mentor figure and ally. This probably has much to do with the fact that Lora Baines-Bradley was a very kind person. It's not her fault she goes insane for a while due to bad code.
MacGuffin Girl: Alan stored the necessary correction algorithms for the digitizer in Ma3a. F-Con wants the codes in order to put their Datawraiths into cyberspace, while Jet (and later, Alan) just want to get home safely.
Summon Everyman Hero: She was looking for a User to fight the corruption. Jet just happened to rush into the lab at the right moment for her to turn on the laser.
Virtual Ghost: It's implied that her resemblance to Lora Baines-Bradley is more than just the "normal" doppelganger issue with Users and their Programs. An email explains that When Lora was killed by the digitizing laser, part of her was left behind in the system. the grieving Alan compiled what was left of her with the Math Assitant AI to create Ma3a.
A formidable warrior program on the Game Grid, she was written by Alan to find Jet and help him out.
Action Girl: Champion of the Lightcycle arena, and well-versed in using a Rod Primitive as a crude, but nasty, melee weapon.
A former Encom security director, he turned against his employers to work for the rival F-Con, and was digitized as part of their experiments. He became a living virus in the process with ambitions to rule all of cyberspace
A God Am I : The power of being "Master User Thorne" went right to his head
Unwitting Pawn: F-con played him like a kazoo to fork over company secrets and undermine Encom for their takeover. Then his invasion opens things up for F-con to perfect the process and send in the Datawraiths.
