Crosses the Line Twice: A lot of the website's humor comes from the many Silver Age comic book covers depicting various petty, cruel, and disturbing acts committed by the World's Greatest Superheroes.
Ensemble Dark Horse: The "Super-Pope-Hat" that Superman is shown wearing on one cover, so much so that one of the site's running gags is the site creator lamenting its absence.
Funny Moments: You can thank Superdickery for earning Superman his very own spot on the Villains Wiki, long before the page was eventually deleted.
Harsher in Hindsight: One proposed Superdickery cover suggests that the reason Superman is a dick is because his father Jor-El was one as well (for wanting to shoot Krypto into space while baby Kal-El cried for his doggy). Well, the Smallville version of Jor-El would years later prove to be not quite such a nice guy himself (even if he ostensibly wanted to protect Clark). Nor would the modern-comics version, who went by the name Mr. Oz.
One entry on a Rex the Wonder Dog comic has him commenting on "the gloriously complete futility of giving a dog a gun". Two years later, Rocket Jump would make a John Wick parody called "Dog Wick", where John Wick's dog uses a gun to excellent effect.
The website's persistent efforts to insist that "Batman's not gay, dammit!" have become a lot funnier since Kevin Conroy, who's voiced the Dark Knight in numerous works, came out as gay in 2016.
Some readers suggest that Superman is this, since in the Silver Age he had to constantly put up with Lois trying to manipulate him into marrying her and Jimmy Olsen trying to learn his secret identity for a quick buck. Add to that all the times the dickery gets turned on him causes some to think that Supes has a massive Freudian Excuse.
It's hard to blame Supergirl for her jerkass actions when her only living relative sent her to an orphanage, was permanently holding her back and telling her what to do and exiled her to space. So... This, this and this? He had it coming. And turning her boyfriends to stone sounds terrible until you remember that most of her so-called boyfriends were dicks and creeps who abused her, insulted her or cheated on her. Seeing as she could simply disintegrate them or throw them in a black hole, she was actually being nice.
Not to mention Batman, who's interpreted as a borderline pedophile but is tormented so much by Superman that it's impossible to not feel bad for him.
Memetic Psychopath: The portrayal of Superman in a lot of these covers led people into thinking this of him.
Moral Event Horizon: According to the site Superman spent the entire Silver Age leaping across the Moral Event Horizon with glee.
Batman, Wonder Woman, Supergirl, Lois Lane and even Jimmy Olsen all have their moments. When they're not getting killed/maimed/having their lives ruined by Supes, at least!
So Bad, It's Good: The cover of Charles Barkley vs. Godzilla invokes this description.
The Woobie: Jimmy Olsen really can't catch a break with all crap he gets put through, Superman's dick moves and all.
Wait, I have a better idea! Let's return to Superdickery! The first troper there gets to live...for a while anyway! Mwhahaha!
