Appearing in Multiple Games
An unfortunate constant throughout the series, Monobear's appearance always heralds the end of the students' normal lives and the start of another mutual killing game. The Mastermind behind the Bear changes with each game; however, his personality remains as unpleasant as ever.
- Anyone Can Die: Not only is he willing to execute innocents if that's how the votes fall, he will even let the Mastermind die if they're targeted as a victim or nailed as a culprit, continuing to act out their plan so long as the students don't correctly guess the Mastermind's identity.
- Bears Are Bad News: If you thought he wasn't already cruel enough in canon...
- Break Them by Talking: Many of his speeches are all about trying to sow discord, distrust and despair among the students.
- Cruel and Unusual Death: His favorite form of punishment. Executions normally provide a twisted take on the culprit's SHSL talent, draw upon their biggest fears, or mock the very things they enjoyed in life.
- Curb-Stomp Battle: Whenever pulling a Hostile Show Takeover on Usami's territory, he gives her one of these.
- Dissonant Serenity: Another trademark of his; to everyone else, a killing game is a horrific experience that leaves most of the participants dead by the end of it, and there's no guarantee the survivors will be well in the head after they escape. To him, it's a delightful display of bloodshed and despair.
- Evil Has a Bad Sense of Humor: Cracks plenty of cruel jokes at the expense of the students.
- Evil Laugh: "Upupupu... Dahahahaha!"
- Exact Words: LOVES this concept. Whether it's rendering a reward from a successful motive effectively useless, twisting the students' words around on them, or using Jedi Truths to continue claiming that he "never ever lies," expect a lot of this from him.
- And there's at least one case where he seems to have outright broken a promise completely, although to be fair it was somebody else's promise rather than Monobear's own, but don't read the following spoiler unless you want an entire game spoiled: in Doubt Academy White, in return for being the Mastermind, Katsuya was promised by Doctrina Artifice that after the mutual killing game was over, Katsuya would be allowed to return back to headquarters and go home. But Monobear overrides DA's promise and decides that it would serve DA's purposes even better if Katsuya was executed. Understandably, Katsuya is royally freaked out upon hearing this.
- Faux Affably Evil: He's a pun-loving, plush teddy bear running a Deadly Game.
- Foe Romance Subtext: He makes flirty jokes about and towards several students and claims to be on dates with them, with reactions ranging from "playing along" to "annoyed" to "too dead to react". Ultimately, however, they're just jokes.
- Hanging Judge: As per the usual form, though he's far more ruthless here than in canon, being more than willing to execute innocents if the other students' votes don't pin down the killer.
- Killer Teddy Bear: To the extreme.
- "The Reason You Suck" Speech: Loves to deliver these, especially after a misvote condemns an innnocent scapegoat to death or the students fail a Mastermind vote.
- Red Eye Take Warning: It'd be strange if Monobear didn't have his trademark red eye.
- The Revolution Will Not Be Civilized:
- In White, Monobear is a member of Doctrina Artifice, a group fighting against The Collective. In order to expose The Collective's true nature to the world, he helps arrange the mutual killing game, and gleefully kills his partner as part of this.
- In Alpha and Omega, he appears to be under the control of the Masterminds, who are working on their own to destroy both groups and anyone else they deem corrupt, supposedly to lead society back into a pure state (although one Mastermind seems all too happy with the violence and injustice the game caused).
- Rule of Three: Big on this. Unlike the original games, he expects would-be graduates to kill three students without being caught. They also have three chances to try and pinpoint the Mastermind... but if they use up all three, that's his victory!
- Sadistic Choice: Many of his motives function this way, especially in Black and White. Also in Black and White, there's one entire-game-spoilering sadistic choice he offers:
- In Black: The survivors are told they can save the data of their dead friends, keeping them 'alive' on hard drives... but doing so also means preserving The Collective's research. Alternately, they can destroy The Collective's research along with their dead friends.
- In White: The survivors also get the option to save their dead friends as data, preserving vital evidence against The Collective that can help bring them down... However, doing so also means supporting Doctrina Artifice, the revolutionary group that started the mutual killing game in the first place. Or they could destroy the evidence, screwing over Doctrina Artifice... but this also means deleting the last traces of their dead friends and protecting The Collective, who brought them to Bright Side as test subjects.
- Schrödinger's Gun: In White and Black, Monobear serves a very slightly different, entire-game-spoilering role: in Black, Monobear is an agent of the Collective, and his goals are the Collective's goals. In White, however, he's part of Doctrina Artifice, an organization whose goal is to destroy the Collective.
- Series Mascot/Villain-Based Franchise: Simply put, there's no Dangan Ronpa without its killer stuffed animal host.
- Shipper on Deck: In Alpha, with how he words some of his answers to investigators, it would appear that he ships Yuu Sagara and Emiko Shiromura.
- Slasher Smile: On his darker side.
- The Sociopath: Arguably even more so than he already was, no less.
- Timed Mission: Only gives the students a certain amount of time to investigate before ushering them all into the courtroom. Trials also have a (real-time) deadline; if somebody fails to cast a vote before time runs out, he counts that as a vote for themselves. Also, the endgame is a timed mission, since in both games, Monobear gives the survivors only 15 minutes to retrieve their stuff and/or their dead friends' data before Monobear blows up the place. In both games, all of the survivors successfully escape in time.
- Took a Level in Jerkass: In Alpha and Omega. For one thing, in both games he personally shoves or throws (depending on the game) Saki and Eikichi to their deaths when they stand up to him. Then in Alpha, he repeatedly impersonates the first victim's corpse, and this was after he kicked said corpse repeatedly. Then he impersonates the second victim's corpse as well, although without the prior kicking this time.
- Torture Technician: What he lacks in straight combat ability (uppity students notwithstanding), he more than makes up for manipulation and psychological warfare against the students.
- Villains Never Lie: If nothing else, Monobear is pretty honest...even when he twists his words to better suit his needs.
- Will Not Tell a Lie: Which is pretty important, given how the investigations hinge on the students asking him questions to help point them towards evidence and other clues.
Appears in every game except Doubt Academy 1, Doubt Academy 5: Mizu, Doubt Academy 5: Kaze, and Doubt Academy 6: Tora
A strange rabbit who appears to be the mascot of whatever area the students find themselves locked into: Magical Miracleland in Black or Bright Side Spa & Resort in White. Unfortunately for everyone involved, she's quickly usurped by Monobear.
- Adaptational Villainy: In Tora.
- Baby Talk: The degree to which she speaks this way depends on the writer.
- Break the Cutie: Her life gets much, much worse once Monobear shows up.
- Brutal Honesty: In White, she very bluntly informs the students right from the start that they'll never be leaving the resort, though she refuses to explain why.
- Bunnies for Cuteness: Some of the students even view her this way themselves.
- Curb-Stomp Battle: Winds up on the wrong side of this when Monobear shows up.
- Hates Being Touched: In Alpha, she refuses an attempt by one of the students to comfort her after being deposed by Monobear, out of fear that it will cause him to harm them.
- Kill the Cutie: In Rot/Rubble, both Monomis are thrown into the aftermath of the mod characters' execution, as both Monobears get sick of their outrage over the twin students' deaths.
- Magical Girl: Magical Miracleland is even based around her character.
- Meaningful Rename: After defeating her, Monobear dubs her 'Monomi'.
- Not Helping Your Case: Whether it's by refusing to explain her side of the story, or, in White's case, bluntly telling the students long before Monobear ever shows up that they'll never get to leave the resort, she really doesn't do herself any favors.
- Slightly mitigated in Alpha and Omega, where she openly tries to defend the students from Monobear and gets beaten up for her trouble. Throughout the rest of the game, it's showed that Monobear will stop her if she tries to give out too much information about the current murder cases or the setting of the game, or if she tries to let the dead contact the living without doing the trials set up in the Isolation Ward, thus explaining why she has to be vague and unhelpful at times.
- Rules Lawyer: About the only times she can effectively stand up to Monobear are when she uses his own rules against him in ways he can't wiggle his way out of.
- Schrödinger's Gun: Her nature is slightly different depending on the game: in Black, she's just a virus that somehow gained sentience, which is why she's completely opposed both to Monobear's mutual killing game and locking up the students in the park. But in White, she used to be human, but the Collective turned her into their agent; as a result, she fully supports locking up the students as the Collective wishes, but is opposed to the mutual killing game that Monobear starts up.
- Transforming Mecha: In Alpha and Omega. She is forcibly changed from a Robot Girl into her rabbit form when Monobear appears; Word Of God compares them both to Transformers.
- Was Once a Man: In White. After The Collective finished experimenting on her, she looked the way she does now.
