- Red Hulk raised Thor's hammer by jumping into space. Also punching out The Watcher, killing the Grandmaster (who is explicitly immortal) and choking the Silver Surfer (who doesn't need air).
- Green Lantern:
- The Guardians of the Green Lantern corps made sure that it would be physically impossible for a lantern to kill one of them. When Hal Jordan kills Krona they are shocked and afraid.
- Bleez was The Starscream before she regains her intelligence. While the other Red Lanterns are growling, "Kill, burn, stab, eat, hate, rage" she was going "Kill... Atrocitus....". In other words, while wearing a ring that turns its host into a mindless berserker, she held onto enough intelligence and focus to choose a specific target.
- Simon Baz using his Green Lantern ring to bring his sister's husband out of a coma. B'dg explained that Green Lantern rings cannot cure illness or bring back the dead, but Baz does the former anyway.
- Then, remembering that incident, he then goes even further in Green Lanterns Issue 3 and Takes The Third Option, choosing to and succeeding in curing the Red Lantern Bleez of her rage - implying by default that he broke the connection with the Red Ring, which is emphasized by her declaration that she can't hear its "noise" in her head any more - and in the process manages to heal her body so thoroughly that her previously-destroyed wings grow back completely intact. He does this using a Green Lantern Power Ring and entirely by himself, despite the fact that by all previously-established rules in the comics, none of it should be possible without also having someone there wielding a Blue Lantern Power Ring. Why or how he's even able to do this is completely unaddressed, other than he very much wanted to.
- Italian comic Sturmtruppen and the Epic Fail of its firing squad tries to execute a prisoner. They managed to miss him and hit the wall behind him while he was holding their rifles pressed directly against his chest.
- Captain America: Breaking the captain's vibranium shield is usually defined as Beyond The Impossible. The few who have done it tend to have "omnipotent" on their resume: Doctor Doom with the power of the Beyonder, the Molecule Man (who described it as weirder than either Thor's hammer or the Silver Surfer's board), Thanos wielding The Infinity Gauntlet, or Odin's big brother, the Serpent. Ultron apparently did it too in Age of Ultron, though we never see how and it all gets changed by time travel in the end anyway. Considering this was Cap's Shield AFTER it was rebuilt in Fear Itself and further reinforced with magical Uru metal, this REALLY says something...but then again, it's ULTRON.
- In the Brightest Day Mera uses her hydrokinetic powers to pull the whole tide away from the shore. Lampshaded by her sister Siren.
- Marvel Zombies: Galactus is eaten by the zombies and while this sounds impossible, considering who this guy is, you have to remember the kind of tactics the zombies use.
- Superman once famously lifted a book that had an infinite number of pages, and thus infinite mass. He also picked up a guy who weighted the same as "eternity".
- In Krypton No More, he and Supergirl fly way faster than light, even though the narrator notes that it should be impossible.
- In Warworld Clark is astonished when he sees the titular weapon satellite is bigger than a star. He can hardly believe something artificial can be so big.
Superman: It's Warworld! I've spotted it — only a couple of light-years away! It's about to pass in front of that white dwarf star and... and... Great Rao — It's not possible! Nothing artificial could be that huge! Warworld didn't pass in front of the star — It passed behind it! And the dwarf star's overwhelming gravitational pull had absolutely no effect on it!
- Later in that storyline Supergirl goes missing, and Superman is determined to find her. He pours on the speed... to the point he shatters the barriers of the reality. Again, he cannot believe it. The Spectre was even called into the fray because of the sheer impossibility of this feat.
Superman: In sanity's name, what have I done? Supergirl couldn't have traveled this far — It's impossible!
- Supergirl: Red Lanterns die if they take their red rings off. However, in Red Daughter of Krypton Supergirl does something no one had ever done before: she took her Red Lantern Ring off and survived, even though it was supposed to be impossible.
- Contest of Champions: In the third series, the contestants are kept in crystalline prisons until their summoners have use of them. When Ares is put in one of these, he manages to break out, to everyone's shock. Of course, Ares is a full-on god.
- Doctor Manhattan's origin story in Watchmen involves Jon Osterman, an ordinary human, getting disintegrated and then putting himself back together particle by particle just by sheer force of will.
- Laff-A-Lympics: Shaggy's yodelling can attract several pigs including a piggy bank.
