Jane Doe is a high-ranking Spanish member of the School of Democracy. She is Big Mouse's wife and seemed to serve as a guinea pig of sorts for his biological experiments. After Big Mouse and Grundla Saha, she is the third SOD member that Ivan encounters in the single-player campaign, making her the game's fifth boss.

She is voiced by Andrea Savo in English and by Hiromi Suru in Japanese.


The only substantial bit of background aside from her marriage to Big Mouse is that she (along with Ivan) was trained in the assassination arts by Isaac Kumano. She did not participate in the city attack that resulted in Ivan abandoning the SOD.

Though she has no definitive role in the SOD, she has an army of ninjas that she sends to dispatch the Delta Force upon their arrival in her village. Judging from Ivan's comments about them, she may have trained them herself.


Mission 5:[]

Jane only made an appearance in Mission 5 of Devil's Third. Through out the mission Ivan believes that Jane was calling him with her singing. When Ivan meets up with her, she greets him in a seductive manner before screaming to turn off the lights and be extension "perform better." As they both fight Jane give out tidbits about Big Mouse's project on a transgenic formula, stating that she and the other test subjects are no longer human, but monsters.

After the fight, Ivan asks her where the S.O.D base is, but she only gives a hint: find the prisoner in the Rhenium Plant. She then tells Ivan that C4 was among the S.O.D. members experimented on before going on to say how much she idolized him. In one last attempt to kill Ivan, she pulls out a knife from her breasts and slowly approaches him. Ivan quickly disarms her and slashes her eyes out, neutralizing her.



Befitting her appearance, Jane is extremely seductive, further proven in her wearing a erotic dress, revealing a lot of her skin and back, even showing quite a bit of cleavage as well as a g-string for bottoms, almost fully revealing her buttocks with some long, see through socks as a battle outfit. She has a cold disregard for others, even to her own husband if her calmness when Ivan encounters her is anything to go off of.

She has a strong taste for traditional Japanese music and clothing, as she is shown in a geisha-like attire and playing a shamisen when Ivan finally discovers her. She is implied to be the woman singing in the background during the second half of Mission 5, thus proving she is also fluent in Japanese.

She also tends to laugh or moan when she grapples Ivan as if she is taunting or mocking Ivan when she puts him in an erotic or sexual hold, fitting her battle outfit and her personality. She tends to try to put Ivan off guard by trying to distract him with her body or tease him about their former relationship, making her a very good seductress. Although this does not work, she can very easily entice and backstab most people she comes across making her very dangerous along with her training that she has received.


While competent with a rifle, Jane is very nimble and is a deadly close-range fighter. During her boss battle, she will attempt to perform powerful kicks upon Ivan that can easily knock him backward and away from her. She will also attempt to grapple him with her legs. She has 4 special grapple animations. The first being a simple frankensteiner, the second being a reverse frankensteiner but instead of her putting Ivan's face near her hip, she plants his face under her butt in a suffocation maneuver until she throws him. Her two final animations can kill Ivan instantly! The first being where she does a spin onto Ivan's head, (as if she is riding him) and then pulling him down onto the floor and begins to put him into a head scissor hold. If you do not get out in time she will snap Ivan's neck and get up. Like other bosses in the game, she will instantly kill you if she gets this attack on you. The attack starts when she goes low to the ground and then starts running. Once she gets close enough, she will lunge and try to do a jumping body scissors, and if connected, she will mount your body, push her hand on Ivan's face, forcing him to the ground, smacks him with her rifle, and then fires at his head.

It seems the Chimera virus gives her increased visibility in the dark and how she set up her battle with Ivan to give her an advantage by causing it be a very low light situation. This is further supported by how after she is defeated, her eyes are visibly different, most notably with her the iris of her eyes now being either a white, or pale yellow color.

Like with Saha, weapon fire is practically useless against her, and due to her fast physical attacks, melee weapons aren't nearly as effective as they normally would be. It's recommended to fight her bare-handed (or with melee weapons), dodging her attacks and waiting for an opening to strike. Fighting her henchmen should be done with the tree between Ivan & Jane Doe, to shield Ivan from her weapon fire. Although the gunfire isn't the best way to deal with her, if you hit her with around 20 bullets in one burst, she will get knocked down for a short while, allowing you to do significant amount of damage. But any melee attacks will make her stand up and fight as normal, so you should continue firing when she is knocked down.


  • "Hello, Ivan. It's been years since you've come to my bedroom." -to Ivan prior to the fight against her
  • "I know you like the lights on... but I move so much better in the dark."
  • "Do you like my eyes? A gift from the Soviets."


  • The name Jane Doe and its male equivalent John Doe are used in several cases for a person whose names are withheld or otherwise unknown. One such circumstance would be a dead body that has yet to be identified.
  • Curiously, Ivan does not kill her after defeating her in battle. He instead slashes her eyes out after she weakly approaches him with a knife. Combined with her quote regarding Ivan coming to her bedroom, it is hinted that she and Ivan may have had an intimate relationship behind Big Mouse's back.
  • Jane's Japanese voice actress, Hiromi Tsuru, is well known as the voice of Bulma in Dragon Ball Z and Naomi Hunter in Metal Gear Solid.
  • She is probably the one speaking to the President of the United States during the epilogue, as she is the only known remaining member of S.O.D. left.
  • She tends to be one of the most famous of the bosses due to her appealing outfit and battle tactics with most videos having the thumbnail of her revealing her battle outfit.
