I see there are several "atypical" types of Kryptonite that go, as yet unmentioned:
One of these is the "brain drain" variety of Kryptonite that Major Disaster invented, which steals only Superman's mental/intelligence abilities (and presumably other powers that operate based on his mind, like Super-Hypnotism and Super-Aim). Its first and only appearance was in ACTION #509.
There is also Anti-Kryptonite, which killed Kryptonians that don't have powers (and was responsible for the death of the Argo City survivors). Lots of people have speculated that Anti-Kryptonite and Slow Kryptonite may be the same substance.
Alternate universe Kryptonite types:
Earth-3 Kryptonite gives Earth-3 Superman additional powers. Where it comes from is a mystery because...on Earth-3, Krypton didn't explode.
In the Morrison Earth-2 story, Antikryptonite gives Ultraman his powers. We learn also in Busiek's "Syndicate Rules" that Ultraman wisely keeps microcapsules of the stuff, time-released, under his skin.
Black Kryptonite makes so much sense, I am surprised they haven't come up with it earlier
To be fair, the idea of splitting Supergirl into good and evil halves is a very old idea: there was a Silver Age Legion story where Red Kryptonite split Supergirl in two: Supergirl and Satan Girl. Satan Girl fought to survive far longer than the 24 hour period a Red Kryptonite effect could exist.
This brings up a point: as interesting as some of these Kryptonite types are, they're not entirely necessary because of Red Kryptonite, which is a "catch-all" for any kind of transformation and effect (since literally, the stuff can do just about
anything to Kryptonians).
This one's here because my friend Jesus thinks it's hilarious.
The Son of Man?

Bonus effect, it makes Superman a belligerent drunk who menaces children.
If there's one faction in our society that isn't beaten enough, it's children.
But there is an immediate effect, as evidenced by Superman stealing and wearing Lois' hat. And then a feathered turbin. And then the hat of a Guard of Buckingham Palace. And Napoleaon's hat. And a crown. It doesn't take long for folks to start thinking Supes has gone a little eccentric. And by "eccentric" I mean "out of his rabbit ass mind."
He's still saving the day and what not, but he's doing so by acting in character of whatever hat he's wearing.
What a fascinating and riveting plot. Superman wears strange hats. WHY?
I hate Mort Weisenger. Hate, hate, hate.
Anyway, I'm reading this guy's blog, and some of this is pretty cool. C'mon, the guy dislikes Chuck Austen. +1!
...Wait! Of all of Chuck Austen's many, many flaws, he points out that Chuck "dislikes women." Like every boring blog in history. -1.
Oh, and this is a -2:
http://sayitbackwards.blogspot.com/2007/09/i-bet-otto-binder-was-green-acres-fan.htmlGod knows I'm hardly a prudish or uptight person at all, but this sort of thing bothers me. "Look, those people are rural and economically disadvantaged! Let's laugh at them!"
Also, the accent? There's a reason most contemporary writers don't "write out" accents. Because if you write "wuz" instead of "was," it shows you look down on the character. There's no reason to write out an accent. If you have an ear for dialogue, their speech can suggest their origins in other ways.
I was just reading Thomas's 100 greatest things about Superman, and it reads like a hall of horrors.
He actually had the SUPERMOBILE on the top 100 things he loves about Superman. -5,000,000!
Even Cary Bates, who wrote the story, hated the Supermobile. Marty Pasko regularly proposed ideas to destroy it.
Marty Pasko was asked about the Supermobile, and his exact words to describe the company that forced him to cram it in? "Those loathesome parasites."
I could tell you the rest, but that about says it all.
Beppo the Super Monkey.
I can understand Krypto being on this list. He's had great moments. And maybe even Comet, because of his tragic love affair.
But
Beppo?
Of all the Super-Pets, he was the absolute worst. He added no relationship, and was officially the moment they went too far.
When he punches giant robots.
If I could go in depth here on why Thomas is wrong...
Superman doesn't "punch" things. That's not his M.O.
How would he beat a giant robot? He'd use his x-ray vision to melt wires, or use superspeed to turn a flagpole in a supermagnet.
Superman's a supergenius that makes inventive uses of his powers. A story where Superman throws a punch is a massive failure of the imagination on the part of the writer.

KILL! KILL! KILL!
As the portion of my brain inherited from my reptile ancestors just activated, I can conjure no rational thought at this point save the urge to kill.
Except one: Edmond Hamilton, the Planet-Smasher, had more talent in a
toenail clipping than that embarassing fool Binder had in his entire body.
