hey u know i be drawing The Black with no tail and the size of an normal Alicorn,
that their weak form, in this pic has The Black in their Strong form and they are horror it self,
and in that form they kill everything i mean EVERTHING!, oh and they have a CM too, it a Red Yin with a blue dot,
it only comes out in their strong form, and they have slit eyes in this form. and the bleed dark purple ,gray blood too.
and don't worry Black isn't going to hurt Lilac their close friends and The Black only kills ponies they don't know.

as in this pic Lilac Tears was walking in the forest (aka the forest were all the dark/creepy/ghost ponies live) and with the 
light from her tears, to see a dying flower ,after she had help the flower with her special tears, she then saw drips of 
blood on it and to look up and see her dark and red misted friend, jumping a bit at their state, but they seem different 
they where taller, they eyes glowed brighter and had a light red slit in them, then she saw that their mouth was 
covered in blood and their mouth usually kept close was smiling with big, sharp, red teeth in a twisted grim that went past their eyes,
and seeing some dark open wounds on their shoulder, which ooze dark purple ,gray blood, and where was no tail was a long, black flowed tail that 
touched the ground and on their flank was a red glowing mark it was yin, with a tiny blue dot, it have to do something with their opposite contour part,
as Lilac stared back at the glowing eyes and horn stained in blood, in a deep, low scratchy voice, they said " Hey Lilac!".

so what u think, i'll do a difference sheet of The Black And The White and their minions too 
so i hope u enjoy!
