Mastermind

With the appearances of Void Gatherers and scalable consciousness, Guardians somehow ascend themselves to a greater species. Mastermind is suitable for their next ascension. Their name symbolizing that they are the smartest and most clever species beyond every theory and astronomical scale. Now, they can understand what is infinity and how it's worked. Even the void, or everything that greater beyond the omniverse has been mastered properly. But there is only one thing that they can never know: Gods - who create everything, including themselves. With their ascension, they reach Type VIII on the Kardashev Scale.
