Here's my backstory for Evolto that combined his canon backstory with MCU Thanos': Evolto was born as the younger brother of Killbus, the king of the Blood Tribe, a race of energy-absorbing godlike beings who were descended from the original Time Lords. Evolto loved his people unconditionally, and when Planet Blood was facing danger due to overpopulation, Evolto requested to kill half of them to give the planet more free spaces. His idea was initially rejected, but eventually his brother went mad for unable to control overpopulation and thus destroy planet Blood for a deal Killbus made with Bill Cipher, forced the survivors, including himself and Evolto, to absorb planets' energy to grow stronger. Thus Evolto not only due to this goal but also wants to "clean the universe" committed mass massacres on several planets, up until when he wiped out the population of Mars, Queen Vernage of Mars sealed him inside the Pandora Box, forced him to wander on Mars for several millenia to come.

Eventually when Rassilon wants to destroy Gallifrey, he made a deal with Bill and Bill told him to open the Pandora Box to unleash Evolto... and the rest is what you know. And then, when Evolto and the Master establish the Magister Corp. on Earth, unlike the regular Time Lords who got human disguises, Evolto has none, thus he possesses several humans over centuries in order not to raise any suspicion.
