Otrera

Otrera is a daughter of Ares and the founder and first Queen of the Amazons.

The Son of Neptune
Otrera was one of the people Gaea revived from the Underworld using the Doors of Death. Otrera began turning Amazons over to her side and planned on taking the throne from the current queen, Hylla. Otrera planned on challenging Hylla to a fight to the death for control of the Amazons as half of them had already sided with her. With the Amazons on her side, she would help Gaea and the other giants when they went to destroy Camp Jupiter. It was around this time that Percy, Frank, and Hazel found the base of the Amazons. Otrera wanted to kill them right away, but Hylla said that wasn't the Amazon way and had Frank and Percy put in cells, but Otrera had her followers guard them. Hylla came up with a plan to help them escape and at the same time make Otrera look bad (as her guards were guarding Frank and Percy). After they escape, Otrera challenges Hylla for the role of queen. Hylla manages to defeat her, but she came back to life the next day as the Doors of Death were unprotected by Thanatos, who had been captured. Hylla beats Otrera two nights in a row before Thanatos is freed from his chains and manages to keep Otrera from crossing into the land of the living ever again.
