Gryphon (No, not a gryphon. gryphons have the head of an eagle. If this mythic creature had a name- I believe it might be "Flion") Not a manticore, manticores have human faces.<<< This amazing mythical creature is a Shedu.
This monster from Greek mythology is called a hydra and is significant because it is the antagonist in many Greek myths including the Second Labor of Hercules. The hydra is a serpent like monster that grows multiple heads in the absence of the first.
