YMMV / Superman/Doomsday: Hunter/Prey

• Complete Monster: Bertron was an alien obsessed with creating the so-called "Ultimate". Every day he exposed a newly cloned child to the harsh environment of prehistoric Krypton; when the child died, Bertron would incorporate its memories into the next child, which would be exposed the following day. Bertron continued this process across the course of his lifetime, slaughtering, in his own words, "thousands upon thousands" of children in an effort to achieve the result he wanted. The creature he finally created was, unsurprisingly, completely insane, and sought to destroy everything it encountered, butchering all the life on ancient Krypton, including Bertron himself, before moving onto the rest of the galaxy. Its name was Doomsday, and in it, all of Bertron's malice would live on, devastating all that it encountered.
• Tear Jerker:
  • Superman is rattled to the point of near-paralyzing fear that he has to go up against a creature that killed him and is even more powerful now. Crosses over with awesome in that he refuses to let fear stop him from doing what's right.
  • Doomsday's backstory, which shows how countless, horrific deaths over the course of several years and a perfect recollection of every single one have made him an irreparably-traumatized little boy in the body of an invincible monster. Doubles as Nightmare Fuel. The only moment of relief is when he is finally able to take revenge on his abusive creator.
