So back in 1982, there was an arc that spanned Wonder Woman issues 291, 292, and 293.
In it, this all powerful being arrives to judge the Earth across every reality in the multiverse, with the power to erase all of them at once in but an instant should it so choose. So this being called 'the Adjudicator' created a series of trials which had Wonder Woman, Madame Xanadu, Zatanna, Supergirl, Phantom Lady, Power Girl, Huntress, Black Canary, Raven, Starfire, and Wonder Girl working to combat this foe.
It was this epic storyline with Wonder Woman facing one of the most overly powerful beings in the DC universe yet I don't see many people talking about it.
