Riot of the Blood



The Riot of the Blood (の, Chi no Bōsō, lit. Rampage of Blood) is a fictional physical and psychological transformation that appears throughout the The King of Fighters series fighting games. It was first shown in The King of Fighters '96.

Overall
The Riot of the Blood is a circumstance that affects individuals with partial Orochi ancestry in their bloodlines. This condition happens when outer influences or an event makes the Orochi blood in a person resist their normal blood. In most common instances, those afflicted go completely berserk, and will continue to do so until the user is either knocked out or comes back to their senses.

Those with full-Orochi blood, including those who are already insane as Ryuji Yamazaki, are not affected by this uncontrollable state and in some cases, instead boosts their strength and energy without ill effects. Orochi and his followers can directly trigger this within themselves and others.

As evident in The King of Fighters Side Story: The Origin of Flame - Shingo Travels Through Time! Let's Go! on what happened to Shingo Yabuki between The King of Fighters XIV and The King of Fighters XV events, the energy unleashed from the Riot of the Blood can also leave a fragment effect of sorts with Orochi's curse upon victims that they scar. Such a presence can be easily sensed by others as a result.

As an attack
For Iori, it's been used as 2 of his Super Special Moves, as his normal version's Exceed in SvC Chaos and one of his supers in Neo Geo Battle Coliseum.

For Leona, she akin to the lore, has been able to enter this state manually, mainly in KOF 2002, NeoWave and 2002 Unlimited Match (though at the cost of her current HP amount). Though it is in XIII she can briefly trigger it for a single attack.

Users

 * Note: All the Hakkesshus can activate the Riot of the Blood anytime and awake the power in other vulnerable people to this blood, due to his condition of Orochi's servants and by their resistance to this power.
