Doomsday vs Reality warping / Space time manipulation?

Let's say someone with reality warping abilities or space time manipulation wants to eliminate Doomsday forever.

1.Reality warping - He blinks doomsday out of existence.

There are forums where ppl think he will come back,but how can you come back from nothing?What do you think?He will stay dead or adapt?

2.Space time manipulation - He travels back in time and space on Krypton and kills Bertron .What will happen?

In both rounds Doomsday is gone forever . I dont see how he could come back from that kind of death :O

@Bo88gdan: That's what i think too but i wanted to hear more opinions

Because of time.

So yes, he will stay dead after he's died and completely warped out, but There are other Doomsdays in other realities and time.
