All standard powers for beings if those type as far as I am concerned.
I never got to read anything with him in it, so I have zero knowledge just to be clear, but it's a pretty safe assumption that the most powerful celestial would be somewhere in the abstract ballpark himself. Unless he just happens to be slightly stronger than a regular one, but they don't usually portray beings like that, I'm assuming he is quite a bit more powerful.
Where in either of your analogies is there an alternate universe version of a mainstream character? Magneto and Batman are from different realities, yet are two totally different characters. No one is referencing a showing by an alternate reality Batman in order to establish something for mainstream Batman. Your analogy is bad.
In Planet Hulk, Hulk withstands a nuclear explosion that disintegrates Caiera. A What If issue shows that she had protected Hulk from the blast using her old power instead of protecting herself and changes it to her protecting herself and Hulk being disintegrated. It is then later revealed in continuity that Caiera only uses her power to protect her unborn child and Hulk withstands the blast on his own with no issue.
So in a What If where the characters should be identical to mainstream, Hulk’s durability is changed significantly.
The Mad Celestials are weaksauce. Sue nearly takes one’s arm off with her force field whereas against mainstream Celestials, she can’t even nick one until she achieves a frequency that allows her to punch a hole in one two small for the Celestial to even notice. You supimpoy can’t use them as proof of what can be done to mainstream Celestials.
Antimonitor bleeds energy. Do you give Imperiex the win over him?
If you want to use semantics, the alternate Reed says “when Celestials bleed energy”, which can be taken that this is not always the case. And referencing alt characters goes against the often cited rules right? Can you cite an instance of an entropy blast harming a 616 Celestial?
And being that OAA is the top Celestial, feats by the others should be the least of what he can do.
In that case, Magneto will be unable to rip the blood from Thomas Wayne, Flashpoint Batman even better. Thomas Wayne will just use guns and shoot Mags out of the sky - his guns and bullets are all alt. universe, so he's immune to Magneto. Thanks for the help in firming up my analogy.
