Pyron

Pyron is a malicious alien being that serves as a boss character from the Darkstalkers video game series. He is an extremely powerful cosmic entity with a body made of blazing energy. His sole reason for being is to destroy and consume whole worlds.

Background
An alien from the planet Hellstorm, whose size largely surpasses the Milky Way. After evolving over many years, he became an extremely powerful cosmic being whose orbital span stretched over 400,000 light years and counting. Over the span of 200 million years, he sought to collect beautiful planets and other celestial objects by consuming them. After traveling across the universe at speeds well beyond light, he lands deep within the Atlantic Ocean to wait for the right time to consume Earth. Originally, he came to Earth 65 million years ago and created the army of Phobos to destroy life on Earth. It is unknown why Pyron didn't consume Earth back then.

Powers and abilities
Pyron has shown faster than light travelling speed before to consume planets in such short time. He's made of pure energy so he can't be hurt by normal means of attacks and especially not by energy attacks which he can absorb. After assimilating planets into himself he adds them to his own orbital path of 400,000 light years. Basically he controls his own private galaxy. He also has super strength, speed, durability, flight, shapeshifting, size manipulation, teleportation, energy manipulation, heat generation, cosmic awareness (He was aware that Earth would have strong fighters), energy absorption, matter transmutation, gravity manipulation.
