Joanna Greenleaf is a character in RWBY and a member of the Happy Huntresses. She made her debut in "Pomp and Circumstance". Joanna has a stoic and confrontational personality, being silently aggressive towards Atlesian personnel such as Marrow Amin, showing disdain towards them. Joanna is the first to attack the specialist after Tyrian Callows' massacre at the political party. Nonetheless, like the other Happy Huntresses, she has a mind to aid Mantle above all else. After the events of Volume 7, Joanna takes charge of the group and spearheads the mission to evacuate Mantle in Robyn's stead, also helping Ruby's Group find cover and rest. Despite this, she still expects the group to help Mantle in turn, showing a disliking towards laziness. Around the Happy Huntresses, Joanna shows a supportive personality, assuring Robyn about her political campaign, to the point of being willing to use both legal and illegal means to accomplish her goals. Later after Fiona falls to despair and breaks down in tears after hearing Ironwood's ultimatum Joanna is quick to join May in comforting and hugging her.
