So, I was talking to a friend of mine the other day (Yeah Rachel, I'm looking at you!), and she was telling me she hates Superman, because he's too... SUPER. And I can understand where comments like this come from: Superman is all-powerful and a goodie two-shoes. That's all good and well, sure. But there's a lot you probably don't know about the Big Blue Boy Scout that might pick up your interest. So without further adurrrrr, let's begin.
10: Superman is NOT the last Kryptonian
A lot of Superman's media will have you believe that Kryptonians are in short supply. We all know about Zod (for those who don't, watch Superman 2 or Man of Steel), but there are plenty of space-gods out there most people are totally unaware of. First and foremost is Superboy, a Supes clone whipped up by Project Cadmus to serve as Superman's replacement "should he turn evil", but was woken up about 20 years too early, and ended up a member of the Teen Titans. Christopher Kent, Superman's adopted cousin, is actually the son of Zod, and being born in the Phantom Zone gives him some pretty nifty additional ghost powers. Kara Zor-El, Superman's ACTUAL cousin, was also jettisoned from a dying Krypton as Superman was... but got lost in space long enough for her to develop sex appeal before crashing to Earth, having all of the standard Kryptonian powers. And that's just to name 3, but there are a bundle more. Which actually reminds me...
9: Superman has a cyborg doppelganger!
Hank Henshaw was a researcher in on a LexCorp space instalation, until cosmic radiation messed with his mojo and his body decayed away. He was, however, able to transfer his mind into the Birthing Matrix, the shuttle that brought baby Superman to Earth, containing the DNA sequences necessary to create new Kryptonian life. Henshaw used this to create himself a fresh new body in Superman's likeness, and has since become a major villain.
After the New 52 reboot (DC's attempt at streamlining their universe to make it more accessible to n00bs), Cyborg Superman was reimagined as Zor-El. If that name sounds familiar, it's because I mentioned this character's daughter already. This one, oddly enough, is more of an antagonist to the Green Lantern Corps rather than Superman himself.
8: Superman is solar powered!
Superman's Kryptonian physiology allows him to absorb radiation from Earth's yellow son to convert into energy. Sunlight is what grants him his crazy powers, and also what makes him mostly invunerable. The supervillain Doomsday almost succeeded in killing Superman, after his reserve of radiation was almost depleted. When Superman uses his powers, he exhausts some of his solar energy. Using too much won't kill him, or turn him human, but it will significantly weaken him.
7: Kryptonians are actually very similar to humans.
On Krypton, Kryptonians have very similar physiologies to humans. This is because while radiation from our sun turns them into, well, Supermen, radiation from a red sun (such as one on Krypton), their cells absorb and process it much in a way that us good ol' humans do. Superman does have his work arounds, of course. In a battle against Solaris III (more or less a living red sun), he made a suit which could repel radiation. This allowed him to retain solar energy he had already absorbed, and prevented him from losing his powers in Solaris' light, but stopped him from regaining power from our sun.
6: Superman does not poop.
Superman, despite being an alien, has all the same organs as a regular human. The only difference is, his lungs and digestive system serve no purpose on Earth, as all the nutrition he needs he can gain from the sun. So yeah. Superpoops, not a thing.
(He can also breathe underwater, so take that Aquaman!)
5: Superman used to be WAY more overpowered.
In the early 50s and 60s, Superman's writers had way more creative license to do whatever the hell they wanted. His current array of powers are his heat beams, cold breath, flight, super strength, super speed, x-ray vision, and invunerability (among a few other, less important traits).
Superman HAS had, however:
Friendship rays, rainbows fired from his fingers that dispelled conflict
Shapeshifting
Time reversal
Force fields
Could learn new languages from watching people's lips
Control over electricity
Supersonic screams
Mind reading
Mind control
And could use his heat vision as a Bat Symbol.
If you don't like Superman before, just frickin' imagine how unhappy you'd be in the 50's. You might just have to mozy on down to the malt shoppe in your jallopy for some sasparilla to forget your problems.
4: Batman could drop Superman like a fly.
Batman is a master tactician, and despite Superman being one of his only friends, he still recognizes that Superman could very easily become a threat. Batman carries a Kryptonite ring stashed away in a lead-lined pouch in his utility belt at all times. And Superman is ok with this! He is fully aware that he could crack Earth in two without breaking a sweat, so he trusts Batman to stop him in the event he ever goes out of control or becomes compromised.
3: Superman isn't the only Superman
We've already been over how Superman isn't the only Kryptonian you should care about, but did you know Kal-El isn't the only Superman to have held the title? During the Death of Superman arc, Luthor whipped up a clone to replace Superman who would be loyal to him, and him alone to do his dirty work. The afforementioned Hank Henshaw also paraded around claiming to be Superman reborn, specifically to harsh his reputation. All the while still, Superboy showed up claiming to be the new improved Superman, and was actually the closest thing to it, other than having anger control issues. We've also had Steel and Eradicator (a surprizingly nice guy given his name) fill in for Superman. In an event where Superman himself could not or did not want to publicly appear in press conferences, Batman, Eradicator, and Martian Manhunter have filled in for him at times. Originally Supergirl tried her hand at the hero business bearing the S logo, but at the time was completely unendorsed by Superman. Also worth mentioning is Bizarro, one of Lex Luthor's earlier attempt at cloning Kal-El, that went super wrong.His powers are basically the exact inverse of Superman, with ice lasers from his eyes and magma vomit instead of cold breath. Kinda silly, but fun to read, for sure.
2: Superman is not nearly as invunerable as you may think
It's a common misconception that Superman is invunerable to everything but Kryptonite. In reality, Superman is just more adaptable than humans, but still weak to all the same things. In any situation where Superman (or any other Kryptonian) is held in containment, red solar lamps are used. This drains them of their power, and in this state, Superman could not block a bullet with his eye. The difference is Kryptonite is radioactive, poisonous to his kind (an well, humans get radiation poisoning from Kryptonite as well). Superman also has no special immunity to magic, or items enfused with magic. So this means a magical weapon, let's use Excalibur for an example, could cut him like any ordinary sword. Superman has also had a form of solar cancer, where his cells were so oversaturated with solar power, that is was causing him to decay. This was in an alternate universe, so OUR Superman has never had this condition, but it stands to reason that he could.
There are also beings who can steal powers from other people (I know you are thinking Rogue. You are wrong). Parasite being the prime example, if he were to drain power from Superman to use himself, he could overpower and possibly kill Superman. Worth noting, while the bones in Superman's neck are much stronger than our own, they are in fact bones and result in death if broken. (Which means Man of Steel's ending wasn't complete bullshit)
1: Superman's mouth is not invunerable at all.
This may seem like a stupid little tidbit, and may not affect how you feel about Superman at all. But the fact of the matter is, Superman is weak to issues of the mouth including, but not limited to, biting his own tonuge, having someone else bite his lips, and chili.
But not just any chili.
It is COMPLETELY CANONICAL that Oliver Queen (the Green Arrow) makes chili so hot, it can actually, PHYSICALLY, burn Superman's mouth. Whether or not this is an indicator of Superman's mouth being a week point, lazy writing, or there for comedy value is totally irrelevent. What truly matters...
It's canon.
