Monodam

 THIS CONTAINS LIGHT SPOILERS FOR DANGANRONPA V3 

Appearance
Monodam's appearance is similar to that of Monokuma, but the part that is black on Monokuma is an olive green color. Likewise, his right eye is gray with a red pupil while his left eye is white. He also has light gray cheeks, meant to represent blushing, and a yellow pacifier in his mouth to represent the fact that he is a child.

While all the siblings are robots, Monodam is more robotic in appearance; his limbs are made of gray, bendable metal, his ears are flat and his body, his face and his forehead appear as different connected parts. The two halves of his forehead also appear to be different parts with the left half being slightly larger than the right half. He also speaks in a stereotypical, monotone robotic way.

When he gets nervous, his ears pop up, releasing steam. Like a rocket, he is also capable of flying forward very fast, leaving behind a trail of bright light. He can also extend and retract his limbs to a small extent.

Personality
Monodam is a child-like robot. Unlike his overly talkative siblings, he is very quiet. For the most part, he doesn't speak even to his fellow siblings, and he is somewhat of an outcast in the group. He sometimes appears a bit shy and seems to be blushing, like during the time when he made his first official announcement.

When he does talk, Monodam speaks in a typical monotone robotic manner, making him appear very emotionless and thus unpredictable. He tends to silently stare at others, with no visible reaction when others speak to him. He occasionally speaks short sentences unexpectedly in a rather loud voice, which may startle others due to his usual silence. The rare moments when he laughs sounds especially unnatural due to his very robotic voice. All of this causes him to come across rather creepy, much more so than his siblings. Like all the Kubs, Monodam imitates Monokuma by constantly calling the students "you bastards" and having his own version of his father's signature laughーa monotone "pu-hu-hu-hu".

Monodam is constantly bullied by Monokid, both verbally and physically, possibly because of his different looks. Monokid has fun making up new ways to be cruel towards Monodam and he also tends to blame Monodam for anything that goes wrong. This is said to be the reason why Monodam has closed his heart long ago. He appears to protest very little or even react against the abuse he endures. However, he later states he strongly dislikes bullying, and in the anthology manga he seems to even break his silence to react whenever someone says the word "bullying". Despite appearing very unresponsive, it's later shown that he seems to act more independent than the other Kubs, like when he arrived to deliver Kubs Pads by the students' request all by himself and mentioned that the other Kubs were asleep.

Later, Monodam's character takes an even darker turn, as he suddenly kills the siblings who bullied him and forces the rest into submission with threats of violence, making even Monokuma creeped out because of his actions. He even forcefully takes Monokuma's place and becomes a temporary headmaster, accusing Monokuma of treating his children like slaves, though later Monokuma claims that he was just taking a vacation and gave the Kubs the place. Monodam turns very passive aggressive, saying that everyone should get along and be friends... or else "he won't forgive them". Claiming everyone is friends and everything should be harmonious, Monodam even appears to be against murders and the killing game, though he later seems fine with them since the class trials increase the students' unity. Monodam physically abuses his siblings whenever they do something wrong in his eyes, since according to him friends punish each other when one does something wrong. Despite this, the other two Kubs, Monophanie and Monotaro, are seen speaking back to him or even ignore him completely. In the end, he ends up killing himself by running into flames during [SPOILERS YO YO]'s execution, because he saw himself as incapable of getting along any longer with his siblings. It's also implied that he was inspired to do this by the other Kubs and Monokuma's talk about how some people get more "popular" after dying since other people then talk about and think about them much more.

Monodam's hidden aggression seems to be hinted at in the Prologue when the Kubs use their Exisals to chase the students into the gym—while the other Exisals are seen taking slow steps, Monodam is seen charging towards Kaede and Shuichi at full speed.

After Monokuma rebuilt him and the Kubs were under a threat of being exploded if they didn't make good arguments, Monodam started to become a little more concerned for his siblings and started to talk more than he used to, and advised his siblings to be quiet and listen to the conversation multiple times. It appears that he is the most intelligent out of the Kubs, as he is capable of staying calm and make logical arguments when the other Kubs were too scared and/or confused to do so, and even when he knew barely anything about what is going on. He also became more aggressive during the final Class Trial and started to participate, unlike in the previous ones, trying to protect his siblings and the Mastermind. After he warned his siblings not to shout so much or else their father will yell at them, he was destroyed by Monokuma.
