Chaos Masters

Chaos Masters are powerful, eldritch abominations of unimaginably vast power. The Chaos Masters come from the Great Dark Beyond, another Multiverse, outside this one. These beings of immense power had in mind to conquer this universe, by simply corrupting and infecting it, and afterwards destroy it, and from its shattered pieces rebuild a new one. They were going to infect Terra-6 universe first, and from it infect everything there is to be infected, however they were stopped by the full-force Phoenix a.k.a. the true form of Ronhin/Cataclysm

Primordial Era / Creation Era
Althouth the Masters have never shown themselves during this era, even then, they were planning to conquer the universe, but they knew it wasn't the right time to strike. To this day, it is unknown why they postponed their conquer.

Old Eon
After many millions of years, Chaos Masters decided that it was right time to strike. The Masters first tried to infect Terra-6 universe, and the group of aproximately 10 of them, worked and succeeded on a ritual and opened a portal to Sortigo multiverse, albeit making their path to infection more clear. However, by the time the ritual lasted, some heroes gathered and assembled to fight them off. Seven heroes stood against them, when they tried to conquer the universe, the heroes failed horribly, Ronhin a.k.a. Cataclysm, as one of them. They entered the Multiverse and defeated heroes effortlessly, leaving them half-dead, and transformed into octopus-like beings and used their giant tentacles to gather up planets and destroy them, drain them of their energy. Ronhin, one of the heroes, half-dead, the host of the Phoenix Force, woke up in a pocket realm, and to him was standing the Strangeress, the woman introduced herself as the "Spirit of Independence" and uttered that he must let go and allow the Phoenix's avatar to enter his soul and body. She said "Unlock your soul, find your... potential", and from which he emerged and summoned the Phoenix's avatar, who enhanced him with incredible powers, and made him nigh-omnipotent and omniscient. After this, the planet on which he was standing was half-burnt because of his reunion with the Phoenix, however, it was said that he received wings, angelic wings, and that those wings blinded everyone who would look directly in them. After this, he was in full control of seemingly infinite ray of powers and abilities and once he spread his wings and embraced the Chaos Masters, they were burnt to ash and banished from this Multiverse. Shortly after, the Phoenix left Ronhin and New Multiverse was made.
