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. During the finals of the '97 tournament, the Riot of the Blood is triggered and she attacks her teammates, Ralf and Clark, but she was eventually defeated. In 2003, the Orochi seal is damaged and she entered the Riot of the Blood, badly injuring Ralf and Clark.
Leona's hair turn red/dark pink. Her pupils are completely white like Wild Iori's (though in some artworks, its appear to be glowing red or glowing yellow or sometimes retains as normal).
During this state, especially with Orochi's heightened presence, Leona goes berserk and will attack anyone on sight. Beginning with The King of Fighters '99, as long as Orochi's presence is kept safely distant, her personality remains unchanged while in control of the Riot of the Blood.
- 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, but akin to Iori's state, she may be more difficult to control and may take more damage as a trade-off compared to her normal version.
Unlike Iori's version of this state, 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. Also unlike Iori, there are often times where Leona in most games can access this state of her own will but at a possible cost (such as half of her current health in 2002; which most likely has spawned fan-made versions of Iori that can do the same).
