The main character in the Artemis story is Artemis herself. She is a central figure as the goddess of the hunt, moon, and chastity. Her brother Apollo also plays an important role in some aspects of her story. And there are the nymphs who are associated with Artemis, often accompanying her in her travels through the forests and mountains.
Artemis Fowl is the central character, a brilliant and somewhat conniving young boy. Another important character is Holly Short, an elf in the fairy world. She is a strong and capable female character. There is also Butler, Artemis's loyal bodyguard. He is highly skilled in combat and protecting Artemis. These characters play crucial roles in the story, with their interactions driving the plot forward.
Since I haven't read 'artemis the graphic novel', I can only speculate. If it's a modern take on the Artemis story, there could be a human character who somehow gets involved with Artemis. This human could be a key character in the story, perhaps acting as a bridge between the world of the gods and the human world. And of course, Artemis herself would be central, and there could be other mythological creatures like centaurs or nymphs that play important roles.
The two main characters are Percy and Artemis. Percy, who is likely to have his own set of skills and powers in the fanfiction world, is beaten by Artemis. Artemis is a powerful figure, perhaps in this fanfiction she uses her archery skills, her leadership among her hunters, or her divine powers to overcome Percy. It's all about the interaction between these two characters that makes up the core of this fanfiction.
In 'Artemis Fowl the Graphic Novel', the key character is Artemis Fowl. He is a young prodigy with a sharp mind. Then there are the fairies. Holly Short is one of the prominent fairies. She is part of the fairy police force and has her own set of skills and values. Another important character is Foaly, a centaur who is a technological genius in the fairy world. These characters interact in ways that drive the plot forward, with Artemis often causing trouble and the fairies trying to deal with it.
There could also be other mythological figures who make an appearance. For example, Apollo, Artemis's brother, might show up in the story. He could bring some conflict as he has a different view on things compared to Artemis. And don't forget about the various creatures in the forest that the hunters interact with, which can also be considered important characters in a way.
The main character is the son of Artemis, who is usually depicted as brave and having a strong connection to nature. There could also be antagonists in the fanfics. These might be new mythical creatures created by the author, or perhaps an evil demigod who wants to use the son of Artemis' power for their own dark purposes. And his mother Artemis may also make appearances in some fanfics to guide or test her son.
Obviously, Percy and Artemis are main characters as they are the parents. Percy, with his heroic deeds and his connection to Poseidon, brings his own set of skills and personality traits. Artemis, the virgin goddess of the hunt, moon, and chastity, has her own set of powers and a very strong - willed personality. Their baby is also a central character, though it may start as a helpless infant but gradually develop into a character with its own agency and abilities.
Artemis Fowl is definitely one of the main characters.
