You can beat some ... but it seems that there would be an endless stream of immensely more powerful Guardians coming for you after each one is beaten ... so it does seem impossible to get through them all ... on the other hand, they do say that "there's always someone stronger out there"
If i understand, the M'kraan Crystal is the point where all the universes (and pocket-universes) are pinned together to form the Multiverse ?
Oh my : The Multiverse is a children play...
Well, if the guardian need to have the power to repel all possible attack in EACH universe, possibly more than one at the same moment (infinite number of universe : Heavy risk), they need the power to do that.
But we don't know if a guardian exist on each universe simultaneously, or if each universe has his own guardians.
And we don't know if the guardian speak true. Why all vs debaters alway think when a character say something, it's not only true, but the exact thing ?
Abstract ? I don't think abstracts WANT to attack the crystal guardians : They are IN the Multiverse. Even Eternity/Death/Oblivion/Infinity are part of the Multiverse (if we forgot the "death out the universe" shit in The End. I have already talked of my theory). If the universes are destroyed, abstracts too.
If we follow the second guardian hint, the third guardian is one million time more powerful than the first, and the first is already more powerfull than Gladiator, who is more powerfull than a X-Man (but it's possible he attacked Gladiator in a sneaky way).
The problem is : I don't think the "1000 x more powerful" is other thing than character talk. For me, the guardian just say "i'm a lot more powerfull than the first, and a lot less than the third".
But well, say "one million" more powerful that a being who is more powerful than Gladiator...
I don' t know the powers of a guardian, but...
First thing, Guardians are not tactical genius : Attack intruder with one guardian after the other is just... classic Mad Scientist Weakness. Sneaky or intelligent characters can overcome them easily, maybe even without battle them.
Two, they are perhaps "one million powerful", but not on all their skills. For example, the second guardian is slow (X-Men can hit him easily, and he miss them).
I don't know the exact number of guardians, but if the third is the last, i think of :
1° Superman One million ;
2° Ion ;
3° Batman ;
4° Magneto ;
5° Prof X ;
6° The Flash ;
7° Mandrake (first incarnation. Think to the original Strange who know how to use magic without limit to crimson band and blasts).

Jamie Braddock would also curbstomp the Guardians, which ever one may come.
Jamie's power is, that he has power over you and everything about you. (He controls Quantum Strings in the absolute sense.
Quantum Strings are what everything is made, and when I say everything, I mean EVERYTHING! Even the Guardians are made of something, and when you break them down to their finest point, you'll find Quantum Strings, and Jamie is the overlord of the Strings.
He may well be the most powerful mutant ever. (I've only recently reached this conclusion)
Too bad that theory is pretty much been called bullshit by every other scientist in the world. It's not even a theory, it's a wild guess. There's never been a single shred of proof that the String Theory is correct or even on the right path to being correct.
Without any proof or any attempts at proof, it doesn't even rise to the level of being wrong.
