I'm not sure specifically as I haven't read the 'Mr Carson the Real Man novel'. But he could be the main character, perhaps a complex individual with his own set of values, dreams, and flaws.
As we don't have a lot of information, Lance could be the main character. He might be an ordinary person caught up in the chaos of the vice city or someone with a special mission.
Lance Vance is a key character in the game. He is likely involved in various criminal activities and plays an important role in the storylines set in Vice City.
The protagonist of Pokemon Yellow is an obvious potential ally. They are on their own journey to become a Pokemon master and could easily team up with Lance. Another could be Professor Oak. He has a vast knowledge of Pokemon and could provide valuable information and resources to Lance. Also, the Gym Leaders in the Pokemon Yellow world could be allies. They are all skilled trainers in their own right and could join forces with Lance when facing a common threat, like an evil team trying to disrupt the Pokemon League.
There could be his best friend, who has been with him through his journey of self - discovery. This friend might be someone who is also part of the same community and understands Carson's feelings and experiences.
Whether Ben Carson's story is true is a complex question. It involves looking at multiple factors such as the reliability of the sources reporting it, his own statements, and independent verification. In some cases, it might be a combination of truth and exaggeration.
