Monotaro

Monotaro (モノタロウ Monotarō) is one of the antagonists featured in Danganronpa V3: Killing Harmony.

He is part of a group called the Monokuma Kubs and also its leader. He is the brother of Monosuke, Monokid, Monofunny and Monodam. The group assists their father, Monokuma, during the New Killing School Life and they patrol inside the Ultimate Academy for Gifted Juveniles.

Appearance
Monotaro's appearance is similar to that of his father, Monokuma, but the part that is black on Monokuma is red on him. Likewise, his eye is black, contrasting Monokuma's and he has bright pink cheeks.

He also possesses a long gray scarf with a silver star pinned to it and a yellow pacifier.

Personality
Monotaro is the leader-esque figure of the Monokuma Kubs, a group of child-like robots. Unlike his siblings, he keeps control of their conversations, though he gets sidetracked a lot.

Despite being a leader, he is the most clumsy of the siblings, giving him a childlike charm.

Compared to Monokid and Monosuke, Monotaro is relatively mild-mannered and less openly hostile towards the students. He also seems considerate of Monofunny and overall appears to care about his siblings despite their constant fighting. Nevertheless, he is evil, just like all the siblings.

Monokuma
Monokuma is the self-proclaimed father of Monotaro, Monokid, Monosuke, Monodam and Monofunny. He calls them his "adorable children", but apparently he also has a tendency to punch them if they annoy him. Considering himself the Headmaster, Monokuma seems annoyed if his children try to steal the show.

Monokuma Kubs
Monokid, Monosuke, Monofunny, and Monodam are Monotaro's siblings. He is their leader.

Trivia

 * Monotaro's name may be based off of Momotarō, the hero of a popular Japanese folktale. Much like Momotaro, Monotaro is the leader of his own group.
 * The Japanese name Tarō literally means "eldest son". Fittingly, Monotaro is the leader of the siblings.
