lightning the mythological demon!!!

Lightning hated Herculeses' little sister Evie ,she was different to her family, she could transform into different mythological and crazy stuff, she could transform into anything she wants. Lightning's favourite thing to do was to scare people. Lightning was as strong as 1000 strong men. At night she haunted people as they tried to fall asleep in fear; her red eye's started glowing in the pitch black night, and she was ready to jump on the inoccent people ,to drink their blood ,and eat the rest of the stuff from the body parts ,and she through the heart in her lava bin! Lightning had a sword that is more powerful than anything only Hercules has been able to get it but then Lightning magically got it back with her thunder and lightning power. Evie has been trying to get the sword for such a long time to keep her family safe but her parents don't let her and she always does what her parents tell her to do! No one has ever defeated Lightning ,but no one knows how she died could it have been Evie?
