Vice

Vice (バイス, Baisu) is a character who debuted as a member of the Iori Team in The King of Fighters '96. Both she and Mature are descendants of Orochi with her being the "cruel" one of the duo. Both women were still being developed during location testing and were likely finished near the end of the game's production schedule.

Story
One of the Hakkesshu, Vice joined forces with fellow Hakkesshu, Mature so as to serve their master, Orochi. The two often took orders from the superior Hakkesshu and one of the Four Heavenly Kings of Orochi, Goenitz, though she didn't like him. Goenitz ordered her and Mature to keep tabs on Rugal Bernstein; a man who desired to wield Orochi's power and had been granted some by Goenitz. They posed as his secretaries to keep a close eye on him and kill him if required. When Rugal kidnapped Saisyu Kusanagi at some point during or before The King of Fighters 1995, Vice was ordered to brainwash him. She succeeded, though not without difficulty due to his resistance to the process, for which she developed a grudge against him.

After Rugal died at the end of the KOF '95 from being unable to contain the Orochi power, Vice and Mature's duties were switched to keeping an eye on Iori Yagami instead, due to his Yagami heritage of the Orochi power. They were to bring him to the King of Fighters 1996 tournament. At the tournaments conclusion, Goenitz arrived and their identities were revealed. When Goenitz was defeated by the combined efforts of Kyo Kusanagi and Iori, Vice and Mature were called upon by Goenitz to help. However, the two betrayed him, deciding to use Iori to attempt to awaken Orochi, having liked his company and hated Goenitz all this time. Their plan backfired however, as with Goenitz's vengeful warning before passing away, Iori entered the Riot of the Blood and the two discovered he was unable to control the Orochi power. Before the two could do anything, they are killed by him. Although dead, the two can take the form of solid shadows in the living realm.

The two continued to haunt Iori in his dreams and eventually revealed themselves to still exist in the mortal realm before the beginning of The King of Fighters XIII. Claiming to not hold a grudge against him, they agree to entertain themselves as his teammates in the latest tournament. The women want to prevent Orochi's power from being stolen by Ash or Those from the Past and convince Iori to join with the lure of confronting Ash.

After the climax of the KOF XIII tournament, Iori's magatama returns to his possession and the weakened Orochi seal begins to strengthen itself once more. She and Mature ask if he truly wants to accept the magatama and the Orochi blood once more, offering him a final chance to completely eradicate the cursed fate from his bloodline. When Iori refuses their offer, the women fade away. They state they will meet him again in his dreams.

Personality
She is a violent person, taking great pleasure in killing others and seemingly immune to their pain. For instance, her grudge against Saisyu began due to his stubbornness to submit to her during his brainwashing. Additionally, it should be noted that she and Mature are not precisely friends, but instead help each other in order to free the power of Orochi.

Despite her brash nature and murder at Iori's hands, she and Mature, quite unexpectedly considering their natures, seem genuinely concerned for his well being and respect his wishes. They were also quite astonishingly concerned more about his well being rather than freeing and helping Orochi when he received his sacred treasure back in KOF XIII. It is hinted their dislike of Goenitz meant they are uninterested in the affairs of the Hakkeshu and in connection, the Orochi as well.

Fighting Style
She is one of the first female grapplers for the series, using a variety of throws to corner and interrupt her opponent's advances. During fights, Vice will often harshly berate her opponent, either by sarcastically remarking the damage she will be doing or by commanding her foe to submit. At first she was able to use more slashing moves, but in further appearances of her, she uses more punches and fierce attacks like body slams and shoulder charges.
