A little extra info on Pyron.
Pyron
Alien
Boss of the first two Darkstalkers games and self-proclaimed Lord of the Living Flame, the all-powerful Pyron is a malignant entity from the distant planet Hellstorm. Omnipotence eventually led to boredom, so Pyron traverses the cosmos looking for sporting opponents and interesting new worlds to add to his "collection" -- and guess which planet he's just landed on? Seeing a potential challenge in the Darkstalkers, Pyron assumes a humanoid shape to conform to the laws of terrestrial combat and gets ready to throw down. He makes a nasty endboss, I'll give him that much. His first appearance is on par with M. Bison and Rugal, but he gets increasingly toned down with each consecutive game.

If Pyron had stayed in his true form, he probably would've f**ked Demetri up, big time.
I think Pyron is almighty, he just lost cuz he was arrogant and fought on the Humans and DSers terms.
