"Are you familiar with a type of being called an "Omnikeizer"?"
"...Superbeings with untold abilities and indescribable power. It happens to be, that we are both Omnikeizers." - The ProtoVordartrian Sovereign Commander reveals to Xenon Sparks the connection between them, both lines spoken by him.
The Omnikeizers are very strange beings. There are only two such beings, both with different origins, one of them completely unknown; and both are extremely formidable. Their powers are said to be incomprehensible. They both share a purpose: to protect the Universe from danger. They have on many occasions worked closely with the Guardians on difficult tasks related to such.
