Ares himself is a main character. And Aphrodite often features as she had a relationship with him. Also, other gods like Zeus, his father, and Athena, who was also associated with war in a different way, could be important characters in ares stories.
As I don't know the exact 'ares graphic novel', but likely Ares himself would be a main character. There might also be other gods like Zeus or Athena if the story involves the Greek pantheon's politics or conflicts.
In the 'ares original story', Ares is of course the central figure. Then there are his divine counterparts. Aphrodite was his lover in some stories, and their relationship added a different dimension to his character. Hermes also had some dealings with Ares. Among mortals, there were those like Achilles. Ares' influence on Achilles' life and actions in war was significant, making Achilles an important character in relation to Ares' story.
There could be Clarisse. Since she is Ares' daughter in the original Percy Jackson series, she might play an important role. She could be either jealous of Percy getting her father's attention or become a sort of mentor - like figure to him. Another character could be Annabeth. She might be worried about Percy being adopted by Ares and try to rescue him or at least check on him regularly.
Since I don't know the exact 'ares infinity stone fanfic', it's hard to say for sure. But likely Ares would be one of the main characters. There might also be other characters related to the Infinity Stones' lore, like Thanos if it's in a Marvel - inspired setting. Or perhaps characters who oppose Ares in his pursuit of the Stones.
In addition to the original Naruto characters, there could be new characters introduced related to the concept of Ares. For example, there might be a mentor figure who knows about Naruto's connection to Ares and helps him understand and control his powers. There could also be antagonists who are either against Naruto because of his relation to Ares or are trying to use him for their own evil purposes.
I assume the sons of Ares would be the main characters. But without reading it, I can't say for sure if there are other important characters as well.
Ares would surely be one of the main characters. There might also be other gods like Zeus, Athena, or mortals who interact with Ares.
The main characters are probably the leaders or key members of the Sons of Ares. They could be the ones driving the action, making the decisions, and leading the fight against whatever opposes them in the story. Maybe there are also some characters from other groups who interact with the Sons of Ares and become important in the narrative.
I'm not entirely sure, but it's likely to feature characters related to the Sons of Ares from the 'Red Rising' series.
I'm not sure which specific novel 'Luna Ares' is from. It could be a character created by an indie author or from a relatively niche piece of literature. Without more context, it's hard to say exactly who this Luna Ares is in the novel.
