Wild Leona, known as "Orochi Leona" or "Awakened Orochi Blood from the Darkness Leona" in Japan (ヤミノナカオロチノチニメザメルレオナ, Yami no naka Orochi no Chi ni Mezameru Reona), is the name attributed to Leona when the Riot of the Blood is activated within her. She first appeared in The King of Fighters '97.
When Goenitz came to ask Gaidel for help to resurrect Orochi, Leona was there. Goenitz activated the Riot of the Blood within her and she murdered her family and the entire village. Years later, in 1997, near the finals of the '97 tournament, the Riot of the Blood once again was triggered and Leona went berserk, attacking her team mates, Ralf and Clark, but she was eventually defeated. In 2003, the Orochi seal was damaged once again and she entered the Riot of the Blood, badly injuring Ralf and Clark.
During this state, Leona goes berserk and will attack anyone she sees, friend or foe. She also tends to vomit blood prior to entering the Riot of Blood. Her hair changes to crimson red (or rose magenta) as opposed of the usual blue.
Beginning with The King of Fighters '99, her personality now remains unchanged with Leona in control of the Riot of the Blood, as long as Orochi's presence is kept safely distant from her.
- Slashing Hands - Leona can cut or pierce with her hands.
- Cutting Aura - Leona can create a cutting aura around her hands and feet.
- Cutting Ball - Leona can create a ball of energy surrounded by several energy blades.
Her fighting style remains unchanged, but she becomes faster and more brutal. Unlike Iori, her actions seem to be more primal in that she has a new walking animation and even a new running animation that enables her to run under mid-level projectiles.
