The Heartfilla Bloodline (FairyTail)
The world of Earthland had much evil that evil taking over. Fairy Tail and Sabertooth the last Hunter clans left in the world. In a dark period of time a weapon was made but could only work with a certain bloodline that died out not long ago. To save the world the scientist Jude Ashley was asked to use what was left of the DNA needed to make two clones from it. From that moment no one foresaw what these weapons would turn into and what really came from that experiment.
