The main character is surely the last man alive. But it's possible that the graphic novel also has some non - human characters, like animals that he interacts with. These could be important in showing his relationship with the remaining elements of the world. Maybe there are also 'characters' in the form of inanimate objects that hold special meaning to him, like his old house which represents his past life.
Most likely the main character is the eponymous last man on earth. However, depending on the plot, there could be secondary characters who are no longer alive but are remembered by the main character. For example, his family or friends from before he became the last one. Their memories could play a significant role in the story.
Since it's about the last man on earth, the main character is probably that last man. But there could be other characters in flashbacks or hallucinations he might have.
The main characters include Jack Sullivan, a brave and resourceful kid. Quint Baker, who is very intelligent and helps with various inventions and strategies. Dirk Savage, who is tough and good in a fight. And June Del Toro, a strong - willed girl. Each of them brings different qualities to the group and they all work together to face the challenges in the post - apocalyptic world of the graphic novel.
There's Jack. He's a brave and resourceful kid who often takes the lead. Then there's Quint, who is really smart and helps with coming up with plans. June is also a main character, a tough girl who can hold her own in a fight.
I'm not sure specifically as I haven't read it. But it's likely the last man himself is a main character. There might also be some characters from his memories or hallucinations if the story has elements of psychological exploration.
There is Jack, who is one of the main kids leading the group.
Batman is the main character, of course. He is the central figure in this post - apocalyptic world.
Jack Sullivan is one of the main characters. He's a brave and resourceful kid. There's also Quint Baker, who is smart and good at inventing things.
There's Jack Sullivan. He's kind of the leader among the kids. He's brave and always ready to face the monsters.
The main character is surely the last man standing. However, depending on how the stories are written, there could be some other 'phantom' characters. For example, the voices he hears in his head which could be remnants of people he once knew. These might not be real characters in the present but play important roles in his mental state.
There may be the last man standing as the central figure. He could be joined by a mentor - like figure early on in the story who gives him some wisdom or skills to help him in his fight for survival. Additionally, there could be an evil overlord - type character who is the cause of much of the chaos in the world of the graphic novel and is the main antagonist for the last man standing.
Given that the title is 'last man stanging graphic novel', the most obvious main character would be the man who is the last one remaining. But it's also possible that there are other entities that play significant roles, such as an antagonist that the last man has to face, or perhaps a guide - like figure that appears to him in his solitude, though this is all speculation without actually reading the work.
