Monophanie is a child-like robot with a feminine personality and the only sister of all the Monokubs. Her personality appears much more gentle than her brothers, which seems to make her somewhat well-liked by her father and siblings, though it can also annoy the other bears who are more openly "evil". In general, Monophanie is considered "the cute one", with a tendency to do cute things like trying to solve the killing game via rock-paper-scissors, or suddenly falling asleep, and liking flowers. Furthermore, she is mentioned to dislike nasty things like gore and bugs. She also appears to be one of the more sensible and intelligent Monokubs, being often shocked and confused by her brothers' crude and confusing remarks. When the siblings begin their usual fighting, she often plays the mediator and seems to dislike arguing, but in the end, she always ends up joining in the fight. While often seeming very gentle and sensitive, she also has a tough side. Despite her kind demeanor, she can speak in a mean and vulgar manner just like her father and siblings, and has a ruthless side. She tends to say things with somewhat mixed messages, beginning her sentence with kindness and then ending it with cruel indications. She may express worry towards others but ultimately seems quite cruel like her other kind.

NOTE: Only reason I put her as child is because they're child-like robots but they have no real ages.
