Hera

The Queen of the Gods, who switched Percy and Jason to unite the Greek and Roman demigods.

Hera, known as Juno in her Roman form, is the Queen of the Gods in Rick Riordan's Camp Half-Blood Chronicles. As Juno in The Lost Hero, she is kidnapped by Gaea and contacts Jason Grace to rescue her. Earlier, she had sneaked out of Olympus and switched Percy Jackson and Jason, wiping their memories, to try to unite the Roman and Greek demigods as part of a plan to defeat Gaea, going against the wishes of Zeus.

Lore & Background

Her cabin at Camp Half-Blood is Cabin 2, the second biggest in the camp; because she does not have demigod children, it is empty. In The Battle of the Labyrinth she helps Percy and the others on their quest. In the 2010 film she is portrayed by Erica Cerra, and in the Disney+ series by Ming-Na Wen.
