Disgaea Wiki

Mao is the main character of Disgaea 3: Absence of Justice. Mao is the #1 Honor Student and son of the chairman at Evil Academy. His goal in life is to defeat his father, the Overlord.



Mao is a demon with pale skin, red eyes, pointy ears, round glasses, and incredibly scruffy white hair. Mao's outfit resembles that of a school uniform, with his jacket being worn more like a cape than what it actually is. His shirt is black and long-sleeved, with four golden buttons arranged 2 by 2 at the end of each of them. His jacket is red with 4 golden buttons on each side of its front opening, and is linked together near the collar by silver chains. The ends of the jacket's sleeves are black with a black pattern just above the ends, made up of a large centered circle and a rectangular band around the rest of the way. The inside of the jacket is colored magenta, and the popped collar has small, rectangular golden studs near the front. Mao wears black dress shorts underneath white shorts that flare exaggeratedly wide towards their openings for his legs. He has a black colored belt with a golden, typical-looking belt buckle. He has black socks and wears large, cartoony red shoes that resemble high-topped basketball shoes with black shoelaces and some white patterning. The bottoms of his shoes are black, and he has one gold button on each side of his shoes' exaggeratedly wide tops, coming to four in total.

His eyes typically appear to be angry, and his resting facial position tends to be a scowl. When Mao is excited or intruiged by something, his glasses will fog up and appear totally white, which is a common trope for characters with glasses in anime.


Mao is a typical Demon: he does not care about the problems of others, will often take what he wants, and uses force to rule over others. His blatant disregard of rules earned him the spot of #1 Student in the Academy as he has not once shown up in class, nor has he ever participated in any school activities, such as homework or volunteering. He keeps more secrets in his Heart Bank than any other demon in the Netherworld Academy, making him the #1 Honor Student. Mao apparently has an "Evil Quotient" of 1.8 million, which he is especially proud of. With his high Evil Quotient, he loves experimenting and studying subjects to gain new information from whatever he finds interesting. Whenever he finds a subject for experimentation his glasses fog over as he starts breathing heavily and drooling, a habit that tends to disturb the "subject" and other people around him. This tendency and the bizarre nature of his research has caused many to label him as a creep and total pervert which he hopelessly protests.

He is willing to do whatever it takes to defeat his father, even if it seems stupid or is something he hates to do. Despite his hatred for humans and heroes, he continually studies them, even keeping an observation journal to record his data. He believed that by learning about them, he can find a method to overthrow his father and take the title of Overlord for himself. Mao's hatred of his father hides the respect he truly has for him deep down, similarly to Laharl (this is noted in the Netherbattle Tournament in Disgaea 4).

When Mao stole Almaz's "Hero" title, it began slowly manifesting within him causing his speech to become more normal and "human like". As the story goes on, he slowly turns towards good, and considers the other people around to be friends, but never admits it.


Disgaea 3: Absence of Justice[]

Spoiler warning: Plot and/or ending details follow.

Mao is the #1 Honor Student and son of the chairman at Evil Academy. His goal in life is to defeat his father, the Overlord. To defeat him, he decides that since heroes are the ones who are able to defeat Overlords, he needs to become a hero to be able to defeat his father. When the unfortunate hero fanboy Almaz von Almandine Adamant arrives, Mao challenges him and succeeds in stealing Almaz's title. Mao decides to challenge his father and after defeating his hand, the hand regenerates and defeats both Mao and Almaz with Mao being surprised at why he lost.

Wondering why he lost, Mao states he should have won due to him having Almaz's Hero title. It turns out that Almaz was actually an ordinary guardsman and not a true Hero, and upon learning this, with Mao decides to return his hero title to him. They go to the Heart Vault and inside Mao's Heart, another Mao named True Heart Mao who tells them they need to open Mao's heart in order to obtain Almaz's hero title. Back outside, Mao decides to go the old classrooms in search of a Legendary Dragon Egg. Mao believes that eating it sunny side up with hot sauce will open his heart up.

Raspberyl decides to tag along with Mao and Almaz stating that it is dangerous to go by themselves to the abandoned classrooms. As they arrive there, they easily obtained the Legendary Dragon Egg and Almaz notes that it was too fast. However, they cannot crack or cook the egg, requiring the help of the Legendary Chef. Inside a cooking kitchen, Mao meets Mr. Champloo who tells him the ways of demon cooking and how he will cook the egg if Mao defeats him in a "cooking battle".

It is eventually revealed that his father is already dead, killed by Super Hero Aurum 200 years ago, when Mao told him his weak points to get back at him for breaking his video games. Mao blames himself for his father's death, and wants to defeat his father's ghost, in order to help him rest in peace.

He tries to return Almaz's "hero" title early in the game, but is unable to because he needed to "open his heart" to do so. He only manages to do this when Almaz dies in the seventh chapter. He then manages to return the title, bringing Almaz back to life and making him human again.

Mao finally decides to go after Super Hero Aurum to take out his anger on him. He goes to his home, the Overlord's Castle and sees that it is all clean, thanks to Aurum. Aurum asks Mao why he is not in the Human World and how Almaz is alive. Deducing that he returned the Hero title to Almaz, Aurum dismisses Mao of not being a worthy opponent and leaves his minions to him. Later on, when the party confronts Aurum again, he states that demons should relish solitude and fights Mao with the help of 3 Diez Gentlemen. Thinking Aurum was defeated, Mao celebrates an early victory until Aurum reappears to them. This infuriates Mao into unleashing his dark powers until all of his friends go into a group hug and manages to calm him down. Aurum is surprised why Mao is not using his dark powers when Mao tells him he has a bigger power, the power of his friends. Impressed by the display of Mao's newfound power, Aurum tells them that they will settle this in the next area.

At the final area, Mao tells Aurum to prepare for death when Almaz senses something is wrong. Aurum then transforms into his true form, a six-winged being with the powers of multiple demons and Overlords. He tells them that he sealed multiple foes into himself so that he can gain more power. The entire party is disgusted by his look but Aurum tells them that a hero should have power when Almaz tells him back that heroes should have courage and love. Mao announces that it is the final battle and fights Aurum's true from.

In the normal ending, Aurum tells the party of what he'd wanted to accomplish and how he had a heavy burden of being a hero. He tells Mao to finish him off and at the last second, Mao decides to spare him and use him for his experiments. After taking Aurum to his lab, the party visits Mao's Dad with Mao noticing he is passing away. Mao has one final conversation with his dad before passing away and decides to become a greater Overlord than him.

In the Super Hero ending, Mao decides not to kill Aurum with him being surprised at why he does not want revenge. Then Mao's Dad speaks to him, saying that Mao has matured and that Aurum is already dead. He goes on to say that the next Overlord will be Mao. The Super Hero mocks Mao, stating that demons must be evil, not soft hearted. Sapphire intervenes and tells him that he raised Mao for 200 years and Almaz states that he should have changed being with Mao. The party convinces Aurum to become Mao's butler once again with Aurum accepting his fate. The scene changes with Aurum, now playing the role of Geoffrey, giving Mao his first task as Overlord.


Main article: Overlord Spawn

Mao using Vasa Aergun in Disgaea 5

Mao's class is initially called Overlord Spawn, but is later retitled Hero, among other things and Overlord in Post Game. He has high Attack and Intelligence aptitudes, as well as decent HP and SP, making him a rather powerful character. He also learns Ice spells up to Giga (Tera in AoD) making him similar to a Magic Knight.

He starts out with a Sword and can also use an Axe, Spear or a Staff. His Signature Evility is Violent Courage which increases his Attack power by 3% times the number of Enemies there are on the field.

His Unique Attacks are Blast Finger, Shine Beam and Vasa Aergun.

Blast Finger can attack a single foe and has a range of 4 (straight). During the move, Mao throws his weapon up in the air, covers his hand in green energy, and jumps over towards the foe. He then grabs the foe and unleashes the energy in a pointblank range blast. He then jumps back and grabs his weapon on its way back down. It is learned at Level 8.

Shine Beam attacks the three spaces directly a head of Mao. During the move, Mao throws his weapon up in the air and covers his hand in blue energy. He then unleashes it into several rays of energy that come at the opponents from various directions. The energy rays then rapidly change directions and grow in size, effectively shredding at the enemy until the rays cover the screen. Once it fades back, Mao catches his weapon and the enemies plummet back down to the ground. It is learned at Level 32.

Vasa Aergun has an X-shaped Area of Effect, meaning it can hit up to 5 enemies at once and has a range of 4 along with it being a Star-based attack. During the attack, Mao is covered in a white aura and rises up off the ground. Eventually, it begins to zoom out off of Mao and has him transform into a gigantic monster. In his new "Monster Mode", Mao then fires 4 streams of lightning at the foes (1 from each of his hands, and 1 from each wing), causing them to rise up off the ground. Monster Mao then begins charging energy into his mouth and then fires out a massive energy blast which incinerates his targets. The attack ends back on the map with Mao normal once again. This skill is obtained after completing 6-2 in the storyline after Mao awakens his true powers in the Heart Vault.


Disgaea 6: Defiance of Destiny[]

  • My new Internet video channel is a big hit. Today, I plan to respond to a request by uploading a video of a Prinny dissection.
  • I spare no expense when studying heroes. I'm developing a device to capture reincarnated heroes when they transfer to a new world.
  • Hey, let me modify that Juice Bar machine. Heh heh heh... Oh, I won't cause any harm. I just want to make it spit out dark matter.
  • I was excitedly panting as usual when some brat asked me, What breath is that? So, I clearly responded, 'Tis my breath!
  • *huff* *huff* Super Reincarnation is very intriguing. I'd love to experiment with it, but I don't have a proper test subject...

Other Appearances[]

Disgaea 2: Dark Hero Days[]

Mao appears in Disgaea 2: Dark Hero Days as a playable character. To get him, you must pass a bill in the Dark Assembly and beat him. His bill is unlocked by unlocking both Mr. Champloo and Raspberyl, as well as having access to the Land of Carnage. During the battle, Mao is level 3200 and has 6 Kurtis Robots with him. Mao is also found in the Item World, where the player can ask him to grant the Magichange 2 ability onto a single monster class character. This saves trying to pass a bill for this which costs mana.

Disgaea Infinite[]

He also appears in the Disgaea Infinite visual novel, having been forced into working as delivery boy by Raspberyl. This leads to a continuity error, as he knows who Laharl, Etna, and Flonne are if he sees them, but when they appear in Disgaea 3, which takes place several years later chronologically, he doesn't recognize them at all. Although, due to the main character Prinny's interference, his recognition of the trio could have been a change in the timeline. The Trio's fame in the area of the Netherworld, in which the novel takes place, could also have caused Mao to know them.

Disgaea 4: A Promise Unforgotten[]

Mao was released in Disgaea 4: A Promise Unforgotten as a DLC character. In his DLC cutscenes, he apparently has taken an interest in Desco for his future experiments. However, he is constantly beaten up by Fuka (and at one time, Vulcanus) for his actions. There is also a Pirate Ship named "Getter Mao" which Mao constructed for dissecting people and is somehow powered by Super Hero Aurum.

Most of Mao's skill were changed from Disgaea 3, with the exception of Shine Beam, which added in a 'hero crown' during the initial animation, which makes him look even more like the Leo Knight in Saint Seiya. He has two different skills, replacing both Blast Finger with Evil Modification, and Vasa Aergun with Evil Transformation ; this last move is a reference to the demon fusion in the Shin Megami Tensei games.

Disgaea D2: A Brighter Darkness[]

Mao appears in Disgaea D2: A Brighter Darkness as a DLC character. He was released on May, 30th 2013 in Japan along with Raspberyl and Salvatore. He retains his three specials from Disgaea 3 with a visual upgrade to all of them, and no longer has a hero crown when using the skill Shine Beam.

Disgaea 5: Alliance of Vengeance[]

Mao returns in Disgaea 5: Alliance of Vengeance as a DLC character in a pack, along with Raspberyl, Salvatore, Almaz, Sapphire and Mettalia. He was seen in a DLC story along with Raspberyl and Salvatore "Field Trip".

He retains all of his skills from both Disgaea 3 and D2, with his skill animation Blast Finger returning back to its original animation from Disgaea 3 although he doesn't throw his weapon in the air (that's not a fist weapon) before executing the skill. He has an overload skill Astaroth Reform, which modifies all the player characters' weapons to have an increased stat of 50% for three turns.

He can execute a combination attack with Raspberyl called Ultimate Bookmark, which was one of the original skills she had in Disgaea D2.

Disgaea 6: Defiance of Destiny[]

Disgaea 7: Vows of the Virtueless[]

Disgaea RPG[]

Mao appears as an obtainable character. Alternate variations of Mao can also be obtained.


“He's the current Dean of Evil Academy. He has an EQ of 1.8 million and loves conducting evil research. He's also a remodeling maniac who loves to drizzle soy sauce on omelets.”

  • In Disgaea 4, the player can purchase paint schemes from the Character Painter for Mao that have the same color palettes as his heart residents such as Savvy Mao, Mao who says Dad, and Dark Mao.
  • Mao's mother is never revealed..
  • During the Post-Game, Mao's stolen item, which he constantly calls 'that' is actually a Super Hero Aurum action figure.
  • In Mao's concept art, it's shown that he has a crescent-shaped scar on his forehead. It can be assumed that this is a parody on Harry Potter, considering both characters share round glasses, a school environment, and an affinity for magic, but it's not always visible due to his hair and has never been mentioned. The scar is slightly visible in his default portrait in story cutscenes, his character icons in Disgaea 4 and Disgaea 5, his Makai Wars artwork and every one of his cut-ins from his debut in Disgaea 3 to his most recent appearance as a DLC in Disgaea 5.
  • Mao is the only character in Disgaea 3 that unlocks their final skill through the story instead of leveling for it (similar to how Yukimaru, Fuka and Killia obtain their final skills).
  • Mao is the only DLC character who previously appeared in Disgaea 4 or Disgaea D2 to have a different Cut-in Image in Disgaea 5, looking almost like the one from his original game, except with an evil grin.
  • Mao's skill "Blast finger" is a reference to the Shining Gundam from Mobile Fighter G Gundam this is evident by the green color scheme of Mao's attack which is similar to the green hand of the Shining Gundam.
  • Mao is a cat lover, whilst disliking dog lovers, confirmed from a quote he says in his lab in Disgaea RPG.
    • This may be a nod to Mao meaning cat in Chinese (猫 māo).
  • In Japanese, Mao’s personal pronoun is “ware” (我), a very old-fashioned and formal personal pronoun normally used when speaking on behalf of a company or group.
