A guy with a blond crew cut and an orange shirt probably wouldn't scare you if you were a supervillain, particularly if you faced him in your underground desert lair and well away from the swimming pool.  Even once he grew out his hair and replaced his pirranha-devoured left hand with a hook, you still might be inclined to think, "Big deal. Still don't look like anything that Chuck Norris couldn't handle."

But, consider this.  Over seventy percent of this planet's surface is covered in water, and that's just the area.  If you consider the depths, the sheer volume of it all, you get a sense of the vastness of Earth's oceans.

Would you want to piss off the one person in charge of all that?

If you answered, "Yes," maybe this example from JLA #41, part six of the "World War Three" story arc, will change your mind.  Here we have a situation where the world is in turmoil, where brother fights brother as Mageddon--the Anti-Sun, the Primordial Annihilator--threatens the Earth with destruction. Only one force can stop the people of the world from fighting one another so that they can unite against the coming evil.  Hint: it's not Superman.

Go ahead.  Pick your fight.  Then watch Aquaman and his crew just roll up to your nation's doorstep and ask your whole damn country, "Whatchu gonna do, now?"

Still feeling lucky, punk?

In the final installment: Aquaman ain't got time for yo' shit!
