In most cases, when we say something is 'based on a true story' in the context of fictional works like 'future man', it means that the creators have used real - life elements as a foundation. The 'future man' is probably not a real individual but rather a composite or an idealized version created from the truths and ideas within the true story. Maybe there were real people who had certain visions or actions that led to the creation of this 'future man' character in the story, but he himself is not a flesh - and - blood real person that exists in the exact form presented in the story.
Well, Future Man is not a graphic novel. It could potentially be a film, a book series, or something else entirely, but definitely not a graphic novel. Maybe you're confusing it with a similar title?
'Future Man' was not a true story. It was a work of imagination in the realm of fiction. The creators crafted a unique and entertaining storyline that didn't draw from actual events.
