Ok, but the answer's going to shock you.
Soda Popinski dropped his left testical during the dead of a russian winter while shipping out crates of vodka in nothijg but a hat and a thong.
This testical scientists discovered and decided to run tests on it, before they knew it the testical and become a living breathing life form... with infinite power. Eventually this testical was dubbed Krazy Intelligent Russian's Ball Yandere.
This K.I.R.B.Y became so consumed by glutoney it began to consume the entire establishment he was at. Eventually gaining so much power he engolfed the entire atmosphere causing earth to freeze. (Hence ice planet in that kirby game i forgot the name of)
Then it came out that papa sakurai of smash brother's fame was the mad scientist who created him.
Basically kirby is a japanese made russian vodka mascot.
The same guy that included joker in smash
