To answer some earlier questions in the thread, if they have already been answered than ignore this:
Waverider isn't an energy being. He is a Linear Man...someone who exists outside of time and makes sure no one screws with the time stream. This is why he didn't simply go back in time and kill doomsdays creator or anything like that. He has the potential to be one of the most powerful beings in the universe, in fact he is, but he doesn't screw with time, he preserves it. He was in fact overstepping his boundaries simply by helping Superman find Doomsday in Hunter/Prey. Also, he wasn't the one who took Doomsday to the end of time, Superman did. He just brought them back.
When he was getting the feedback from Doomsday, he was trying to find somekind of central nervous system or anything he could shut down in order to kill him. But the result you saw in the previous scans.
Many people are under the impression that Doomsday is just a big dumb rock that's really strong and don't give him enough credit. Doomsdays real power is he can sense his opponents weaknesses. You could argue that that's why he was marching towards metropolis in the Death of Superman arch...if he hadn't, Superman wouldn't of had to get into a close up brawl with him and he could have won. But Doomsday knew that Supermans weakness is his friends and family...supes had to get down and dirty with him in metropolis to save Lois, Jimmy and everyone.
He did the same thing in Hunter/Prey. When he was on Calaton, he was marching straight for the central reactor to destroy it. Again, Superman had to get down and brawl with him to keep him from destroying the reactor. And he would have won that fight hands down too if it weren't for Waverider's bracelet being used.
