Cupcake is the younger brother to Bonbon - whom he sees as more of a parent than just an older brother because of being mainly raised by him. He even calls him "Mama Bonbon" like others do. He is apart of the Illicit Faction as well.

His appearance is bright and sweet - and his personality is very child-like. Everything from his wide grin to how he acts is childish. He is pretty much dependent and obsessed with candy and sweet treats as well. This is because of a verity of reasons and not just because he is a Candy Monster.

Cupcake here, despite how he looks and acts, is built. Very muscular and tall as you can see in the picture. It makes more than one person just meeting him do a triple take because of how at odds this can be to them. It's pretty funny that Bonbon still calls him "Little", but that's because of always see Cupcake as his little brother/might-as-well-be-son (as Bonbon sees Cupcake as more of a son than a brother, just as Cupcake sees Bonbon more of a parent than a brother). As his body would tell you, he is physically strong.

His magic mainly deals with candy and sweets. He can enlarge, enhance and shrink down candy and sweets to fight with. For example; he can take a lollipop, enlarge it and enhance it to make it more sturdy and use it as a broad sword or as a war hammer of some kind. He can also add EFFECTS/ILLS to his candy too. For example; adding a EXPLOSIVE EFFECT to some round, small candies and throwing them, turning them into a type of bomb. It all just depends on his creativity and how much magic he wants to use.

Having said that he is very creative - he fights and does impossible things like a child who was never told what was impossible and a child whose creativity was encourage to high degrees.

Although very child-like in terms of antics and personality, he can and will get serious if a line is crossed. Nearly no one has ever seen him without some sort of childish face on (grinning, smiling, pouting, whining like a child pretty much) and he usually always has this wide grin/smile on his face - however once he loses it, it can and will unsettle and feel so wrong to everyone. The swirls in his eyes stopping for once - he is not a Monster you want to make mad.
