A request from snowdragongal a shocked Death Dancer.
This was the day when the Autobot burned her home and killed her sparkmate the Decepticon Death Blade. Her name was Dainty Dancer until that day, but after that... she named herself Death Dancer, in memory of her mate.
I hope I drew her well.

I don't own Transformers Prime, but I own Death Dancer concept.
