Lucifer - King of hell,
Lucifer was there when the girl was hunting him down, with a grin he appeared behind her, seeing sam and Dean where not close enough to help her, he grinned and said,
"Well hello Little girl, Lost?" his voice was so icy, so cold that you could have sworn your soul was frozen in place at his voice, a male with dark facial expression stood there a grin on his face, you could hear some hellhounds beside him growling softly, but Lucifer made them fall quite and grinned back at the girl his eyes flashed with hellish fire for the hunters. He grinned walking closer,
"Hello Miss Huntress it's odd to see a huntress here, mostly guys take up such hard work guess your different, lets see just how different you are" he laughed harshly the room seemed to spin slightly as his eyes flashed black and red color.
