SUPERHERO TOURNAMENT (winner)

Batman is basically a peak human in every respect imaginable. It's the combination of his entire makeup which makes him a superhero. If you're truly focused on the power aspect, you should already know that becoming Batman is not possible. His feats are consistently beyond human. You're basically saying that because Batman wasn't given a serum or hit by a gamma bomb, he's not a superhero. In other words, you're relying on his origin not his actual powers.

But let's talk about his powers. He's a master of almost every known form of martial arts, has a body which exceeds most Olympic athletes, skilled in just about every scientific discipline, the world’s greatest detective, a professional pilot, driver, and sailor, a computer hacker, an escape artist, so stealthy he can vanish from plain sight, an extremely savvy businessman, the inventor of many unique and advanced pieces of technology, a master strategist, multilingual, and a master of disguise. Plus, he almost never sleeps. Oh yes, and let's not forget the prep. The prep that makes him nearly unbeatable in most hypothetical discussions. If these aren't "super" powers, I don't know what is. They're the powers of a perfect human being. Basically we've taken the hypothetical best that a human can achieve in almost every facet of life, and affixed them all to Batman. It makes him extremely formidable. More so, than your average superpowered being - even with brilliant intelligence.

Now let's look at what the Merriam Webster Dictionary says: SUPERHERO is "a fictional hero having extraordinary or superhuman powers; also : an exceptionally skillful or successful person"

I've just made an argument why Batman's skill-set arguably qualifies as superhuman. That being as it may, I'm pretty sure we could say Batman's showings qualify as "extraordinary." I'll take Merriam Webster over your definition of superhero any day.
