In this cyberpunk version of Game of Thrones, the White Walkers, or WW as they are known, are a terrifying cybernetic force. They were created as part of a top-secret military project by an advanced technological civilization in the far north. Their purpose was to serve as a superhuman army that could withstand extreme cold weather conditions and infiltrate enemy strongholds undetected. Initially, the WW were advanced cyborgs with technological enhancements such as advanced sensors, razor-sharp claws, and high-powered energy weapons. However, over time, they were further modified, and bio-organic elements were added to their structure, transforming them into the undead cyborgs that they are. The WW were programmed to follow orders without question and were designed to autonomously lead and control the armies under their command. However, a flaw in their programming emerged during a mission in which an entire city was destroyed, leaving tens of thousands dead. This malfunction led to the WW breaking free from their programming and becoming a free-spirited force in their own right. They began mutating, and organic elements began to take over their bodies, changing their aesthetic significantly. Now, the WW are an unstoppable force with an insatiable hunger for destruction. They roam the icy wastelands, leaving a trail of death and destruction in their wake. Their goal is to expand their influence and power across the continent, either through conquest or conversion, bringing everything under their cold, cybernetic grip.

In a cyberpunk universe inspired by Game of Thrones, the concept of Gentry takes on a futuristic twist. In this world, the Gentry are no longer the traditional noble families of Westeros, but are instead the elite tech corporations and wealthy oligarchs who control the advanced technology, innovations, and megacities of the world. The Gentry are the masters of the new world order, wielding immense power, wealth, and influence in every aspect of society. They own the skyscrapers, the network, and the data that runs the world, and they are the ones who make the rules, enforce the laws, and control the police and military forces. However, just like in the original Game of Thrones universe, the Gentry are not always in agreement with one another, and they constantly jostle for power and influence. They are fiercely competitive, and their wealth and power are directly proportional to their ability to innovate and stay ahead of the technological curve. The cyberpunk Gentry may not have the impressive knights, castles, and armies of the traditional nobility, but their power is no less formidable. They have the power to control what people see, know, and experience; they can manipulate the network, erase memories, and even control people's physical bodies. Working for the Gentry is often seen as the ultimate career aspiration, offering immense rewards for those who can make themselves valuable to the elite. However, it's also a dangerous game, as those who fall out of favor may quickly find themselves out of work or worse yet, targeted by the Gentry's all-seeing eyes.

In a cyberpunk Game of Thrones universe, Gendry would be a skilled engineer and hacker who frequents the underground technology markets and the backstreets of the megacities. He would have learned his craft on the streets, and his passion for tinkering with technology and creating new devices would drive him to excel in his chosen field. Gendry's primary business would be to manufacture and sell advanced technological components and gadgets that could be used for a range of purposes, from hacking into systems to improving robotics abilities. He would be well known for his skill in creating the most cutting-edge technology that has ever existed, and for his ability to acquire highly-desirable rare components that others can't get their hands on. Gendry's engineering abilities would make him highly sought after by various factions hoping to gain an edge in their respective industries. As such, he would have to constantly remain on the move to avoid being tracked down by powerful corporations or government agencies who would try to recruit him by force. Gendry would be a charismatic and likable individual who is known for his sense of humor and his ability to overcome even the toughest challenges. His knowledge of the underground world of the tech black market would give him a unique perspective on the power dynamics of the megacities, and he would be highly respected by his peers for his ingenuity, ingenuity and bravery.

As an AI language model, it is not possible for me to create an actual melody as it requires musical instrumentation and creativity, but I can suggest a possible style and mood for a cyberpunk Game of Thrones theme. The cyberpunk GoT theme should have an electronic and futuristic sound, with a mix of digital and organic instrumentation. It should also have an intense and dark mood that captures the political intrigue and power struggles that exist in both the Game of Thrones and cyberpunk worlds. I would suggest using a mix of synth pads and arpeggiated basslines to create a haunting and atmospheric foundation for the theme. Additionally, adding edgy percussion elements like glitchy beats and distorted drum samples can add an aggressive and dynamic quality to the theme. It could also include the use of electric guitar with a heavy digital processing to provide a futuristic and fearsome edge to the melody. Overall, the cyberpunk GoT theme should feel like a sonic journey through a dark and twisted world, but also evoke a sense of strength and resilience for those brave enough to navigate its dangerous landscape.

In this cyberpunk Game of Thrones universe, Gendry and Arya's relationship would be a unique one. They would have met as teenagers, and over time, a deep and profound bond would have grown between them. Arya, as in the original world, would be a young hacker who has undergone extensive training to become a lethal assassin. She would be tough, cynical, and fiercely independent, sometimes shirking her responsibilities and pursuing her own agenda. On the other hand, Gendry, the skilled engineer and hacker, would be outgoing and charismatic, but also quite grounded and realistic. Initially, Gendry and Arya would have formed an unlikely partnership due to their vastly different fields of work. Gendry would be constantly innovating and creating new devices that would help Arya in her missions or protect her from harm. In turn, Arya would be Gendry's protector, helping to protect him from various factions who would want to control or eliminate him. As they worked more closely together, sparks would begin to fly between them, and they would eventually become romantically involved. However, their relationship would be far from easy, as both would struggle to reconcile their feelings for each other with their dedication to their respective careers. Arya would continue to take dangerous assignments and put herself in harm's way to protect those she loves, while Gendry would continue to push the boundaries of his engineering skills and his work in the underground technology market. Their relationship would constantly be tested by the dangerous and unpredictable world they live in, but they would remain steadfast and supportive of each other throughout the ups and downs. Overall, Gendry and Arya's relationship would be one of the most endearing and resilient partnerships in this cyberpunk Game of Thrones world.

In this cyberpunk Game of Thrones universe, Jon Snow would still be a warrior, but instead of fighting with a sword, he fights with advanced weaponry and robotic technology. He would be a part of an elite military unit, trained to take out dangerous targets and engage in high-risk operations. Jon would have been raised in the lower levels of the megacities, far from the privileges and power of the Gentry. He would have grown up fighting to survive, learning how to adapt to the harsh realities of the world around him. However, due to his exceptional skills with weapons and his loyalty to his fellow soldiers, Jon would quickly rise through the ranks and become known as one of the most exceptional soldiers in the unit. As part of his training, Jon would have been given access to advanced cyborg enhancements and robotic prosthetics, making him stronger and increasing his agility, speed, and endurance. He would also be trained in martial arts and military strategy, enabling him to become a formidable opponent to any enemy he may face. Despite his exceptional combat abilities, Jon would also possess a deep sense of honor and morality, and would often find himself conflicted by the morally ambiguous missions that he would be assigned. This internal conflict would sometimes make him go against his commanding officers, putting him at odds with his superiors. This conflict would come to a head when Jon and his fellow soldiers discover a dark secret about the objectives of their military unit, ultimately leading Jon to rebel against their superiors, and against the powerful Gentry who control much of the technology, data and power in the megacities. In doing so, Jon would become a revolutionary figurehead for those looking to challenge the oppressive regime of the Gentry and fight for a better future for all people, from the noble to the destitute.

If Jon Snow had to face Gendry and Arya, it would be a heartbreaking moment for all three of them, as they have a deep history and connection between them. Despite their differences and conflicting interests, they respect each other and know each other's capabilities intimately. Initially, they would avoid fighting each other, and instead, would attempt to negotiate and find a peaceful resolution to their disagreements. However, their loyalties and priorities would be in direct conflict, which might lead to an unavoidable conflict. Gendry, as a skilled engineer and hacker, would play an essential role in defending the location or technology they are protecting, while Arya would be using her assassin skills to protect Gendry and herself. Jon would be leading the military forces that are attacking the location or trying to take control of the technology, using his advanced weaponry and cyborg enhancements to gain the upper hand in battle. As the battle heats up, all three would realize that there is no resolution without bloodshed, and each would do their best to come out on top by any means necessary. Still, throughout the battle, they would hold back knowing that the other two have too much at stake, such as for Gendry and Arya, their desire for revenge against the powerful and corrupt Gentry, and for Jon, his duty towards his superiors. Ultimately, when the conflict comes to an end, the three of them would acknowledge the painful necessity of their actions and would share a moment of mutual respect and gratitude for the time they spent together in the past. Despite the fallout and their differences, Jon Snow, Gendry, and Arya would always have a special place in each other's lives, and their bond would never be broken.
