Doomsday

Doomsday was a weaponized beast created by Darkseid, using Superman's Kryptonian DNA and Solar Energy that was possibly extracted by Desaad during the invasion of Earth. He was then sent to Earth via Boom Tube.

The creature was first unleashed onto Krypton, only to be repelled by Colonel Zod using an ancient Kryptonian warsuit. This conflict became known as Remembrance Day, a solemn occasion mourning those who died during the calamitous battle. It became something of a mixed occasion for Kryptonians following Zod's exile to the Phantom Zone. Doomsday would later be exiled to the Phantom Zone, but appeared sporadically in the material world, eventually breaking free altogether. Decades later, the creature would come to Earth, wreaking havoc.

Doomsday can be described as a pure incarnate of killing, bloodlust, and destruction as the only purpose his existence is to kill any lifeform that he encounters regardless of whether it is dangerous to him or not. He demonstrates anger and rage in certain situations like when he is insulted. He also is shown to be aware of his abilities and being able to use them precisely.

While murdering any and all life he encountered, he appeared to instinctively aim for the strongest opponent, as when fighting Superman, he ignored other people. Though should Superman take a break from exhaustion, he would revert to killing every sapient life. Here, you can take the role as a superhero, a civilian, etc.
