You do realize, I hope, Spider-Man has defeated with his bare hands Firelord, a very well written fight - it took him two comics and half of the city was destroyed lol - but an angry Spider-Man took down Firelord.
He also defeated Titania, who will eat DD, Cap and Wolverine for breakfast. He put up a very good fight against Morlun (probably Hulk level) and defeated him with his brains. He beat Rhino (not Hulk level, but not far from it) several times, at least two times with his fists only.
He has fought the Hulk countless times, and even humiliated an extremely angry Hulk...
He ripped apart the armor of the future Iron Man. He even gave Silver Surfer a serious run for his money, though in the end, he was of course defeated, like 90 % of the characters will get their ass kicked by SS. But he put up a very good fight, better than one would think. Please tell me, what are DD, Cap and Wolverine going to do to Silver Surfer ?
Spider-Man always holds back when fighting low level villains or heroes such as DD and Captain America. This is a fact. When he goes berserk however, he can hang out with the Big Guys (for a good while). Cap, DD and Wolverine are NOT big guys.
Spider-Man's enemies are on a much higher level than those of Cap, DD and Wolverine (speaking about raw power, not intelligence).
Time to face it.
