That sounds like an exciting project. JoJo's Bizarre Adventure, created by Hirohiko Araki, is known for its unique characters, intricate plotlines, and imaginative use of supernatural abilities known as "Stands." When developing your main character for a manga inspired by this series, consider incorporating some of the key elements that are emblematic of JoJo's storytelling style. Please go ahead and share details about your main character such as their personality, background, motivations, and perhaps their Stand ability if they have one. I'd be glad to hear about your creation and offer any feedback or ideas you might find useful!

Simon sounds like an interesting character, especially with his diverse background hinting at a rich family history that could play a role in his personal narrative. The blend of different cultures may provide for a variety of influences in his behavior, values, and maybe even in his Stand ability. Here are some thoughts and questions that might help you further develop Simon and his story: 1. **Personality and Motivation**: What is Simon's personality like? Since you mentioned he's based off of Denji from Chainsaw Man, does he share similar traits such as being straightforward or possessing a strong desire for a simple life? What drives him? Are there personal goals or is there a specific reason he wants to or needs to travel between realms? 2. **Realm Travel**: How did Simon acquire the ability to travel between realms? Is this a power related to his Stand, or is it a separate ability? Consider the implications of realm travel in your story--is it common knowledge in his world, or is it a secret art? Are there costs or consequences to such travel? 3. **Stand Ability**: If Simon has a Stand, what is its name and what are its powers? In JoJo's Bizarre Adventure, Stands are often named after Tarot cards or bands/songs, and their abilities can be highly conceptual or symbolic. How does his Stand relate to his character and the overarching narrative of your manga? 4. **Occupation**: His 9-5 office job seems to contrast with the idea of a realm-traveling adventure. How does this job tie into his story? Is it a cover for his real activities, or does it serve as a grounding element in his otherwise fantastical life? There could be a compelling reason he holds onto a mundane job--does it connect to his motivations or provide a unique setting for part of the story? 5. **Visual Style**: Simon's attire is simple and somewhat classic; it could provide an interesting visual counterbalance to the typically flamboyant style seen in JoJo's Bizarre Adventure. Consider how his clothing might get adapted or change when he's using his powers or in different realms. 6. **Relatability**: Having an old-school phone like the Nokia 3310, is an unusual choice for a modern character and one that implies either a preference for simpler technology or a statement about his character. Is there a story behind this choice? How does this tie into his character, and does this throwback technology play a part in the story? 7. **Challenges and Antagonists**: What kinds of challenges does Simon face, and who are the antagonists in your story? Are there specific enemies or rivals he encounters in various realms, and how do they reflect or contrast with his own character and values? Start fleshing out Simon in these areas, and you'll be well on your way to creating a solid main character for your manga. Remember, the heart of JoJo's Bizarre Adventure lies in its larger-than-life characters and the dramatic, often intricate battles they engage in, underpinned by deep character motivations and relationships. Make sure Simon stands out in a similarly bold and unique way!

Simon's backstory is quickly becoming as complex and intriguing as many of the characters found in JoJo's Bizarre Adventure. With such a long lifespan, he could have an extensive history to explore, contributing to his character development and the overall narrative. Here's how you can flesh out these details: 1. **Age and Appearance**: Being born 400,000 years ago gives Simon an extraordinary perspective on human history. His longevity needs an explanation that fits within the logic of your manga's universe. It could be due to his Stand ability, a specific event that happened to him, or maybe a unique trait of his lineage. His youthful appearance can also be a focal point of intrigue or humor within the story, especially if he maintains it with mundane means like "good skincare." 2. **Military Service**: His service in the Vietnam War can be a pivotal part of his character, shaping his views on violence, duty, and morality. You can delve into how his experiences there affect his current behavior and decisions. It's also a rich opportunity to illustrate how he has (or hasn't) adapted to changes in society over time since the war ended. 3. **Ex-Relationship**: His ex-girlfriend from Spain adds a personal and potentially emotional dimension to his life. Consider how this relationship influences his actions and attitudes, especially if there are lingering feelings or unresolved issues. This relationship could also provide cultural and narrative links to other characters or story arcs. 4. **Living Situation**: Living in a small apartment in New York--Realm 530--grounds his character in a relatable setting despite his fantastical background. It provides a contrast to his extraordinary abilities and history, potentially making him more accessible to readers. The designation of New York as a 'realm' suggests that the different realms might correspond to real-world locations, reimagined or hidden within the normal world. This aspect can be expanded upon to build the world's lore and intricacies. 5. **Stand Abilities and Challenges**: Given Simon's past and abilities, he likely has faced myriad challenges and adversaries. You'll want to consider how these past encounters shape his present situation. Does he have a Stand? If so, what is its power, and how does it relate to his ability to travel through time or his military history? What kinds of enemies or rival Stand users has he confronted due to his long existence or during his inter-realm travels? 6. **Cultural Heritage**: With such a diverse ancestral background, it would be interesting to see how his heritages influence him. Maybe certain aspects of his character or his Stand are inspired by his various cultural roots, creating a rich tapestry of influences that affect his actions, values, and interactions with others. As you further develop Simon's story, you might want to ensure that his actions and motivations are consistent with his complex background. This long-lived character with a foot in many historical periods provides a wealth of narrative opportunities, and readers will likely be drawn to the mystery and depth of his existence. Balancing the fantastical elements with relatable human experiences will be key to making Simon a compelling protagonist in your manga.

Snow seems to embody a mysterious and somewhat enigmatic persona, which can add a sense of intrigue to the group dynamic around Simon. Drawing inspiration from Ghost of Modern Warfare 2 (Call of Duty), Snow could play the role of the cool, calculating, and possibly stoic character who contrasts Simon's potentially more open or vibrant personality. Here are some questions and points to consider while further developing Snow: 1. **Personality and Role**: If Snow is "often bored and edgy," what are his motivations for being involved with Simon and his adventures? What drives him despite his outwardly indifferent demeanor? Does he have a personal stake in the story, or is he drawn to the thrill of action and conflict? 2. **Combat Style**: Snow's choice of traditional ninja weaponry like katanas, caltrops, and shurikens implies a preference for stealth and possibly close combat. This could be reflective of his training or personal interest in martial arts. How did he acquire these skills, and how do they complement Simon's abilities during their adventures? 3. **Appearance and Anonymity**: Snow's visual design with a ski mask and a hidden hair color may mean he values anonymity or has a reason for concealing his identity. You might explore the narrative reasons for his secrecy--is it a past he's hiding from, protection for loved ones, or maybe a mystique he cultivates for himself? 4. **Character Development**: Edgy characters like Snow run the risk of becoming one-dimensional if not given depth and growth over time. Consider introducing backstory elements or personal challenges that gradually reveal more about him, softening his edges and making him a more relatable and complex character. 5. **Relationship with the Main Character**: What is Snow's relationship with Simon? Are they longtime friends, or did they meet through unusual circumstances? How do they complement each other in terms of personality, combat, and navigating the story's challenges? 6. **Stand Ability**: If Snow has a Stand of his own, what might its powers be? If you aim for a JoJo-inspired narrative, it could reflect his stealthy and combat-oriented persona. You'll want to ensure that his Stand's powers and its relationship to Snow flesh out his character without overshadowing other elements. 7. **Past and Motivation**: You've mentioned that Snow is in his early 20s, which is not a very extensive period to build a dark or complex past. However, you can delve into what formative experiences he has had that made him who he is. There might be a pivotal event that led to his edgy nature or his path crossing with Simon's. Consider how this backstory informs his actions and how it might come into play throughout the story. As you develop Snow and his interactions with Simon, you can use the differences between the characters to create exciting dynamics and tension within the group. Remember, the companions of the main character often have their own arcs and contribute significantly to the depth of the story. Make sure Snow has personal goals, relationships, and development beyond just being Simon's friend to fully realize his character.

Ryan adds a flamboyant and colorful aspect to the group with his unique sense of style and vivid personality, which appears to contrast with Snow's more subdued and mysterious nature. His inspiration from Raoul Duke suggests he might have a wild, unpredictable streak, and an inclination towards substance-fueled adventures and countercultural attitudes. Here are points to flesh out Ryan's character and role in the story: 1. **Personality and Background**: Borrowing from Raoul Duke's hedonistic and gonzo journalism approach, Ryan could bring a sense of recklessness and a penchant for finding trouble. How do his Cuban roots and upbringing in the United States influence his worldview? What drew him to journalism, and how does he approach his work given his bold nature? 2. **Contradictions and Complexity**: A character dressed in a Hawaiian shirt and a fedora working as a journalist is indicative of a certain degree of nonconformity and flair for the dramatic. Is his colorful attire a representation of his personality, a way to disarm interview subjects, or perhaps a brand he's built for himself? 3. **Relationship with Main Characters**: How did Ryan become part of Simon's circle? Was he drawn to Simon's adventures for a story, or did they have some other connection? What role does he play among Simon's friends - is he the chronicler of their exploits, the comic relief, or perhaps the wildcard always bringing in an element of surprise? 4. **Skills and Contributions**: As a journalist, Ryan would have investigative skills, an eye for detail, and lots of connections. These could prove invaluable to the group, especially if they find themselves in need of information or navigating complex situations. How does Ryan's ability to gather and analyze information contribute to the group's objectives? 5. **The George Wallace Incident**: Peeing on George Wallace's car is a politically charged act that speaks to a disdain for the segregationist politician. It indicates that Ryan might be willing to take bold, perhaps even reckless, actions for what he believes in. This kind of rebellious streak can offer insights into his political stances and moral compass. 6. **Dynamic with Snow and Simon**: Considering Snow's and Ryan's vastly different characters, there may be interesting dynamics at play. Perhaps Ryan's brash nature annoys Snow, or maybe they have a mutual respect for each other's skills. With Simon, Ryan could form a strong bond based on shared experiences or through a mutual fascination with the realms they explore. It's important for Ryan's character not to be reduced only to his quirks or apparel but to delve into the substance behind his gonzo facade. Through his interactions with the group and the evolution of his personal story arc, you can showcase the depth and growth he experiences throughout the manga. Remember that each of these friends should serve a specific purpose in the narrative, presenting their own unique perspectives and being integral to the unfolding of the plot. Ryan might be able to open doors (literally and figuratively) with his social savvy and journalistic instincts, complementing Simon's physical or supernatural abilities and balancing Snow's introverted stealth.

Tetsuo adds yet another distinct dimension to the diverse cast of characters in your manga. His unique appearance, profession, and personality traits suggest he will bring a mix of light-heartedness and a potentially darker edge to the story. Tetsuo's interest in video games and his choice of attire indicate a complex character who doesn't conform to traditional gender norms and possibly incorporates elements of Japanese pop culture into his identity. Here are some ideas and considerations to expand on Tetsuo's character: 1. **Fashion and Identity**: Tetsuo's choice to wear a Japanese school girl outfit indicates a nonconformist and possibly provocative personality. Is his outfit a form of self-expression, an extension of his profession as a hairdresser, or does it have deeper personal or cultural significance? How is his fashion sense received by those around him, and does it affect his interactions? 2. **Profession**: Tetsuo's occupation as a hairdresser suggests he might be a creative individual with an interest in aesthetics and personal image. Does he use his profession to connect with others, gather information, or is it simply a job he's passionate about? His profession could also be a means for light-hearted moments or even involve storylines related to his clients and their stories. 3. **Personality**: You've described Tetsuo as having a "playful and somewhat evil attitude." This could mean he enjoys teasing others or has a mischievous streak. Does his "evil" side have a darker implication, or is it more about playful rebellion against norms? How does this manifest in his interactions with the group and the choices he makes? 4. **Cultural Background**: Being from Japan, Tetsuo can bring aspects of Japanese culture into the story. His background might also be relevant to certain plot points or his worldview. How does his heritage mesh with his current lifestyle and interactions with characters like Simon, Snow, and Ryan? 5. **Hobbies and Interests**: His love for video games can offer common ground with readers and other characters, and perhaps influence his way of thinking or strategy--akin to how gamers often approach problems. How do his gaming skills and his passion for games influence his role in the group and in the adventures they undertake? 6. **Submissive Tendencies**: Tetsuo's preference for being dominated is an intimate detail that reveals a lot about his personal life. How does this trait inform his relationships within the group or with other characters in the story? 7. **Relation to the Main Cast**: What does Tetsuo bring to the table in terms of the group dynamic? His playful attitude can lighten tense situations, but the "somewhat evil" aspect might suggest he can also complicate the group's plans in interesting ways. How did he become part of Simon's circle, and what is his relationship with the other characters? Overall, it's vital to handle Tetsuo's character with sensitivity and depth, avoiding stereotypes or reducing him to his quirks. His flamboyant personality and unique style offer the potential for both comic relief and poignant moments. His skills as a hairdresser might even be leveraged in surprising ways, such as disguises or gaining entry into restricted areas. As with all characters, ensuring he has a well-developed backstory and motivations will help Tetsuo to stand as a compelling, integral part of your story.

Having Simon share a living space with his diverse group of roommates offers a perfect backdrop for exploring the dynamics between the characters in more intimate, day-to-day settings. Co-habitation can be a rich source of both conflict and camaraderie in storytelling, as it forces characters with distinct personalities and backgrounds to interact closely. Here are some points to consider as you develop the relationships and storylines revolving around their shared living situation in NYC: 1. **Living Dynamics**: Think about how each character's habits and personality traits would play out in a shared living space. How do they handle chores, privacy, and personal space? Do they have shared routines or traditions? Are there recurring points of contention or sources of bonding? 2. **Character Interactions**: Close quarters mean that characters can't easily escape each other's quirks. Tetsuo's playful nature might clash with Snow's edgy attitude, while Ryan's journalist lifestyle could draw the group into unexpected escapades. The development of their relationships can be a compelling subplot or even central to the main narrative. 3. **Backstory Reveals**: Characters living together will inevitably learn more about each other's pasts. This presents ample opportunity for backstory reveals through shared conversations, memories, and perhaps even conflicts that arise from misunderstandings or deep-seated issues. 4. **Personal Growth**: Sharing a home in a city like New York can challenge each character to grow. They might learn from each other's different life experiences and cultural backgrounds. Personalities like Simon's may evolve significantly from the influence of his roommates. 5. **Practical and Plot-Relevant Uses**: Their apartment can be a sanctuary, a base of operations for planning their adventures, or even a plot point itself--if, for instance, it's located on a ley line or has some hidden significance in the lore of your manga's universe. 6. **External Relationships**: The introductions of friends, love interests, and other external characters into their shared space can create new situations that test and reveal different sides of the main cast. 7. **Conflict and Resolution**: Close proximity can lead to conflicts, which are essential for the development of the narrative and the characters themselves. Resolving these conflicts can demonstrate the characters' deeper bonds and growth as a makeshift family. As you continue to develop these characters and their shared narrative, keep the focus on how their living arrangement reflects and affects their personalities and interactions. Use the apartment as a microcosm of their world, teasing out the complexity of their relationships while they navigate the larger adventures and challenges of the story. A shared living space creates plenty of opportunities for humorous, dramatic, and heartfelt moments that will endear your characters to your readers.
