Not many people think too deeply about Cherubi. After all, what's there to notice? It's an unremarkable pokémon, just another grass-type. Little do they know that behind that easy-going smile there's a merciless cold-blooded murderer.

For some bases, let us first review Cherubi's breeding method. Cherubi like all pokémon is born from eggs. However there's an interesting fact about the eggs of these pokémon: they always result in twins. There's actually a 1/1000 chance of triplets being born, but the fact is, every egg will result in two Cherubi. However where is the second twin? You guessed it: it's that little fella hanging around.

The egg contains a limited source of nutrients needed for normal growth and development. It's simply not enough for both, so even before they are born, the twins engage in a tug-of-war for the delicious nutrients. The winner becomes the dominant Cherubi, a jolly old fellow with tiny but powerful legs, developed eyes and a plump nice body. The loser however suffers a much worse fate. It's almost always blind due to not having the eyes properly developed so it keeps them shut all the time. The digestive track didn't develop either, so they can't eat or drink anything, and thus must rely on their twin to give it enough to get by through the stem. The legs don't develop either. The result is a little ball-shaped underdeveloped Cherubi that wouldn't last 5 minutes alone.

A question that plagued scientists for decades was "Why does Cherubi keeps its failed abortion of a brother with it?". Kind of curious since the twin is a first sight nothing but a burden.
