These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Magnificent Bastard: Darkseid orchestrated the whole pact in such a way that Scott Free/Mr. Miracle would escape, allowing him to go back to war with New Genesis. He's also responsible for corrupting many characters in manipulative ways.
Mainstream Obscurity: While the New Gods aren't exactly mainstream, many in both the American comic book industry and fanbase often refer to how influential the series was. Yet one gets the impression many of those people never actually read it, especially since a full collected edition of Kirby's series was only published in 2007-2008. Notable examples include Jim Starlin (Anti-Life as depicted in his Cosmic Odysseydoes not work that way!) and Grant Morrison (who admitted to this in his introduction to Jack Kirby's Fourth World Omnibus Vol. 1!)
Moral Event Horizon: Darkseid has crossed it many times. Granny Goodness is guaranteed to cross it at least once anytime she appears.
My Real Daddy: Paul Levitz is widely considered the guy who made Darkseid a big name villain with the Great Darkness Saga. Similarly, Giffen and De Matteis are credited for making Oberon and Big Barda cool (as well as bringing Mr Miracle out of obscurity), while Walt Simonson made Orion cool.
In Final Crisis, when Granny Goodness's reduced to an evil spirit, who possesses a Green Lantern and creates centipede energy constructs.
Her capturing Batman also counts, as far as Granny not only single-handedly defeating Batman but also her speech where she exclaims how completely and utterly screwed Batman is now that she has him prisoner.
Most of Apokolips counts, but specifically Granny Goodness. Dear God, Granny Goodness. What to say about someone whose entire purpose is basically child abuse?
