The Monokuma Kubs, or "Monokubs" for short, (モノクマーズ Monokumāzu lit. Monokumarz), also known as the "Children of Monokuma", are a group of five child-like robots that claim to be the children of the malicious robotic bear, Monokuma featured in Danganronpa V3: Killing Harmony.
They're all incredibly one-dimensional, especially when compared to the rest of the cast (though this might have been intentional).
They serve little to no actual purpose to the story.
Speaking of that, the only purpose they do serve?
Scenario 1: A body is discovered, and before anyone can start wondering what happened, the Monokubs show up to take up some minutes of screen time for unfunny jokes and pointless shenanigans.
Scenario 2: It's the middle of a Trial. Something major has happened, something that will influence the rest of the story, and then the Monokubs show up to take up more minutes of screen time for more unfunny jokes and more pointless shenanigans. Heck, they even do this during the final trial, right when the Mastermind is revealed!
It gets to the point where even Monokuma is fed up with their bantering and decided to kill them off one-by-one, along with the students in the executions.
More often than not, they only exist to be unfunny comic reliefs, as most of their dialogue tries to be funny, but ends up coming off as painfully unfunny. Not to mention it often ends up getting in the way of major events (which on top of the mastermind's reveal suffering from this, Shuichi and the other students' reactions to witnessing the Kaede Akamatsu's execution are also briefly cut off by them rambling on about Monokid's death, who even they considered annoying in spite him being their brother).
This applies in-universe as well, as the audience watching the Danganronpa reality TV show finds the kubs annoying as well. Even Shuichi Saihara (who keep in mind is one of, it not the, most kind-hearted and selfless characters in V3) doesn't seem to care when they get blown up in the final trial. And when they engage him in a Rebuttal Showdown to save themselves, he coldly reminds them that none of the deceased students wanted to die either (save for Ryoma Hoshi).
They're all brought back near the end, only to be killed, AGAIN.
He's a clumsy and incompetent leader (though he can be a minor exception).
He's pretty dumb and even outright admits he doesn't pay attention sometimes.
He can be pretty gross at times, as he seems to have an odd fixation on his butthole. He's also weirdly interested when Tsumugi Shirogane says she went to restroom, asking whether she took a firm or a soft dump.
He's is a bear with rocker motifs who never shuts up.
He's a cruel bully towards Monodam, the most likable of the group. Almost all the time Monokid spends onscreen is him mistreating and abusing the latter.
The rest of his time onscreen is dedicated to him annoying his siblings. So much so that even they hate him and Monophanie outright says "Screw him" when he dies (despite them all being shocked at first after he was killed).
He manages to be least intelligent of the Monokubs, and is either too stupid or too out of it to do anything other than screaming, swearing and picking on Monodam.
Speaking of swearing, his vulgar behavior gets annoying pretty fast.
She's literally just Monomi from Danganronpa 2, but with a ton of disturbing fetishes.
She's seemingly the nicest and most even tempered of the Monokubs, and apparently dislikes violence and gore, often suggesting that the killing game be changed to something more peaceful. But despite this, she still cooperates to keep the game going and makes no real effort to stop it, which is just hypocritical.
She tends to puke a lot, onscreen (and in multiple colors as well). Which is just disgusting.
She acts waaaayyy too happy when being licked by Monokuma, and has more than once shown an interest in Monotaro, who need we remind you, is her BROTHER.
He has an obsession with money, frequently suggests ways of making money, such as making merchandise of the Exisals.
Hypocrisy: During the penultimate Rebuttal Showdown, he tries to defend Tsumugi Shirogane by saying that bad guys never wear glasses, when he himself wears glasses.
He doesn't show any gratitude for Monodam whenever he defends the former for his slip-ups. This ultimately results in his destruction.
He's the most robotic of the five (though he's also the most likable).
As aforementioned, Monodam is the most popular and well-received of the group, due to the fact that he doesn't speak as much, and kills Monokid and Monosuke. Even people who especially loathe the Monokubs often agree that Monodam is the most tolerable.
Monotaro can also be a slight exception as well.
Thanks to issues brought about by his mounting memory problems, Monotaro decides to cast the rules aside and join the investigation during Chapter 4. Unfortunately, he's reprogrammed back to "normal" by the time of the class trial, though.
The concept of a family of Monokuma-like A.I. is pretty interesting and creative, even if the outcomes ended up being annoying and unlikable.
It's hard not to feel at least a little bad for them when Monokuma destroys them one by one for making bad arguments, especially when Monotaro and Monophanie begin crying and begging Shuichi to let them win so they can live.
Some of the voice actors for the Monokubs also voiced other anime and video game characters : Patrick Seitz (the voice actor for Monokid) voiced Dio Brando in JoJo's Bizarre Adventure , Sean Chiplock (Monotaro) voiced Natsuki Subaru in Re:Zero - Starting Life in Another World and Natalie Hoover voiced Sonia Nevermind in Danganronpa 2 : Goodbye Despair , Catarina Devon from One Piece and Yolko from Sword Art Online.
