First of all, let me say thanks for the props everyone.Second of all, everyone who's a big DC fan, should get ready to HATE me(if you don't already), because I've discovered something that's going to PISS you off. However it will also explain how the Anti Matter Universe, was able to expand and become more powerful, while retaining it's original size(which I already covered in my last post). Just remember, I didn't come up with this stuff, I'm only pointing it out.
Now we'll start with the beginnings of the DC Multiverse(I've included the first two pages of it's origin for anybody who doesn't know it, but the important stuff doesn't start until the third scan)...

This one's a little more important, which is why you get a thumbnail for it(even though I already posted it)...
Now the reason I say that the third scan is more important, is because it shows the universes overlapping to a degree, without actually interacting. Why you ask? Because the universes that made up the DC multi-verse, weren't laid out side by side, they were kind of stacked within the same space, and were separated by vibrational wavelengths that kept them from actually interacting with each other. This is first mentioned on the first page of the first book...
See at the bottom it says that the universes were vibrating and replicating. Now I would also like to bring your attention to the part(in the same narration box), that says "what should have been one became many", because that's about to be important.
So what does all this talk about the universe fracturing and the resulting universes being separated by vibrations have to do with anything? Well I'll get to that after I show you these scans, which point out something important about the multi-verses origin...
This is from the first book. Look at what it says in the upper right hand panel. "The universe once divided into many parts...Each one different, independent, yet somehow WEAKER than the whole". What does this mean exactly? Well to put it bluntly, it means that even though DC at the time was a multiverse, it was a weak multiverse that only contained as much power as a single universe. And before anyone tries to call BS on the fact, here's the Monitor saying the same thing in the forth book...
"The universe was split apart at the dawn of time...each part WEAKER than the whole it was meant to be". He also says that the universes are separated by by vibrations and time.
When all of this is taken into account, here are my theories on the matter...
About AM's power increasing with the destruction of the positive matter universes... Well his universe obviously didn't grow outward and actually become larger(because of the dimensions given for it and because of the impossibility of an infinite number of universes being placed side by side). It would be more accurate to say that it grew in DENSITY(it's the best word I could think of to describe it). It became more real, and more like the ORIGINAL universe in overall power.
This also means(and THIS is what's really going to piss some people off), that even at the height of his power, AM wasn't even as powerful as a SINGLE intact universe(because there were still 5 universes left out to complete the whole). So not only could he not take Multi Eternity, he probably couldn't take the universal aspect of Eternity either. His power falls just shy(5 mini universes to be exact).
Before everyone starts attacking me as a "DC hater", let me just say that I've spent the past three days going over all this stuff, but there IS a chance I missed something. So if anyone has any evidence which goes against all this, feel free to bring it to the table, and I'll address it. Also, I have no idea, on how powerful DC's universe is NOW. All this stuff relates only to the power of DC during COIE. I'm not saying that Marvel's universe is STILL more powerful.
