Manganese 

The fictional inhabitants of manga (hence the name) and anime, who are for some reason almost exclusively Caucasian in appearance, despite the fact that most of them must be Japanese by ancestry.

The Manganese have many abilities that other human beings do not. They can dramatically vary the size of their facial features as well as generate a massive drop of sweat when they encounter suitable emotional stimuli.

Potassium Manganate VII 

When in solution, this particular compound gives an absolutely gorgeous pink-purple colour.
As a solid, it is black, but sparkly black!
It has therefore endeared itself to many a Chemistry A level student!

It is also known as Potassium Permanganate.

"What's your favourite colour?"
"Potassium manganate VII in solution..."
"???"
*sigh* "PURPLE"
