Titus won't cave DD's face in, and you've obviously been triggered by your hatred for the Doomsday character. First off Doomsday was adapting while fighting Superman. Superman even noticed a strength increase while in battle with him. I have no idea where you're getting this bullshit that has Titus caving DD's head in, but it's wrong. Doomsday would be the one caving Titus' skull in. Guess which one of these guys don't have internal organs? Not to mention that there is a more recent appearance of Doomsday in Action comics, and he was stronger than Superman.
