Name: Chimera, chimaera, chimaira
Features: Three headed lion that could spew flames
Source: Greek Mythology
Habitat: Greece, City of Lycia
The Chimaera had the head and body of a lioness and was capable of spewing flames.
Her tail was scaly and had a snake’s head at its tip. At the centre of her spine was the head of goat.
Seeing her was an omen for storms, volcano eruptions and shipwrecks.
When she was full grown she killed many people with her powerful three heads which were able to attack independently of each other.
She was able to resist many attempts on her life until she met her fate - a poisoned spear thrown by Bellerophon.
Of course he was riding Pegasus at the time which, I am sure had plenty to do with the final outcome of this deadly quarrel.
