List of characters in the Camp Half-Blood series
Hera/Juno - The Queen of the Gods and the Goddess of Marriage. Hera plays a small role in The Titan's Curse but is one of the gods who help Percy and the others in their quest in The Battle of the Labyrinth. At the end of the book, Annabeth and Percy offend her because she did not care that Luke was gone or that Daedalus and Pan were both dead. She especially dislikes Annabeth and curses her like how Ares cursed Percy in the 1st book. She thought Luke, Pan and Daedalus were better off gone. Cabin 2 at Camp Half-Blood is dedicated to her, but is perpetually empty; as the goddess of marriage, she has not given birth to any demigods. In spite of this, Hera meddles with the affairs of many demigods. In The Last Olympian she has a minor role where she congratulates Percy on his victory rather disdainfully and says that she would have to let him and Annabeth live a little longer. She returns as Juno in The Lost Hero in which Percy Jackson has disappeared. She has been kidnapped by Gaea and contacts Jason Grace, the new protagonist and asks him to help her. It is then revealed that as Juno, she snuck out of Olympus and exchanged Percy and Jason to try and unite the Roman and Greek demigods. She goes against the wishes of Zeus in this regard because she wants to save everyone – gods, demigods and mortals from the new evil. Juno also admits that she is bitter towards heroes and demigods because she does not have any of her own. Juno, Hera's Roman counterpart, is more warrior-like and more disciplined and rebellious. Juno even states that Hera would not have disobeyed Zeus, but Juno would.
