1. Lobo eating a city always leaves me confused as hell. I would get it, if it was pure toon force (reality warping)... but that's not really what Lobo is about as far as I know.
2. Hulks pants surviving nukes.
3. Superman lifting the Earths weight for 5 days. I've always hating this to a point, where I don't even acknowledge it. To me it's not about the weight itself. Couldn't care less about it. To me it's such a disservice to the character. To think that THE SUPERMAN would waste 5 days worth of time somewhere in a bunker, instead of being out there and saving people... it's just... it's such bad writing.
Any abstract, cosmic, or universal level being in comics. They all are able to be continuously beaten by people they could blink out of existence and just generally remain dumb, petty ****s for billions of years despite having untold power and intelligence that should be well beyond even the likes of Reed, Room etc. That's gotta count for something
Monica Rambeau's neutrino form makes no f***ing sense whatsoever. Her power is to turn into any type of electromagnetic radiation. The force-carrying particles of the EM field, i.e. photons, are (exactly-)massless spin-1 gauge bosons whereas neutrinos are weakly-interacting almost-massless spin-½ leptons. Completely different thing! It's like Beast Boy suddenly shapechanging into a rock, or Colossus turning into water form. F*ck that illogical sh*t.
