Bonbon's overall design stayed the same for the most part when compared to his old sketch. Just upgraded to look better and with more details overall.

Bonbon is the older sibling out of the two and raised Cupcake since he was a newborn. He is 13 years older than Cupcake, whom he calls "My Little Cupcake" even if the Monster is in no way little anymore.

He is a very motherly Monster. He honestly acts like everyone's Mother to the point where nearly everyone calls him "Mama Bonbon". He will even act motherly (scolding, cleaning faces, cooing at, etc) towards enemies while fighting and people who could break him in half if they truly wanted to. It's just how he honestly is. However do not like this fool you, he is not someone to take lightly.

He mainly creates candies and sweet treats, and his magic is based around that and his cooking utensils. He can enlarge and shrink kitchen tools and items to fight with and/or hide away. He can also turn people into cooking ingredients or something sweet, them having an EFFECT/ILL to them depending on what they turn into. He tends to use them in his baking. His food also either has an EFFECT or ILL to them - him using his baking as a means of assassination when needed or healing up others or giving them a nice EFFECT to fight with.

Despite knowing one can die from his cooking depending on if he wants you dead (as all his treats look delicious and taste it too no matter if it is deadly or not) his treats and candies are very sought after.

Bonbon is apart of the Illicit Faction and is Pernicious Desire's (Underlust!01!Papyrus - Second in Command of the Illicit Faction) right hand you could say.
