In a straight up fight.
Mephisto, Juggernaut, Beyonder, or anyone else who doesn't primarily fight Spider-Man doesn't count.

Can I just put 10 in a list of no particular order? Or does it have to be from least to most dangerous.

• Carnage
• Venom
• Morlun
• Green Goblin
• Morbius
• Lizard
  
• Kingpin
  
• Scorpion
• Kraven the Hunter
• Sandman
  

No particular order, but I do think Carnage is the most dangerous.

• Carnage
• Electro
• Doc Ock
• Venom
• Green Goblin
• Kraven
• Sandman
• Scorpion
• Hobgoblin
• Kingpin
  

1.Morlun

1. Carnage
2. Venom
3. Green Goblin
4. Doc Ock
5. Jackal
6. Sandman
7. Electro
8. Kingpin
9. Kraven
10. Punisher ( he has clashed with him many times)

The only one that shouldn't really be there is Jameson. All the rest are pretty powerful and apart from the Burglar aren't the type to go down after one punch.

Where is Morlun and Carnage? Venom and Spider-man had trouble beating Carnage together..and nobody on that list could beat Morlun.And how the hell is Harry Osborn more dangerous than Kraven?"

"Except JJJ ignores the "in a straight up fight" part.I agree that JJJ is one of spidey's worst enemies but that wasn't what I was asking."

Well, I didn't read that, lol.

"

he is his own worst enemy............lol

Jameson is dangerous because he have the power of the press. He can manipulate people against Spider-Man (of course, he's already doing this). But second place? Nah..

Here's my list;

1) Morlun (not the "biggest enemy" but definitely most dangerous one)
2) Green Goblin (N.O.)
3) Venom (Eddie Brock)
4) Carnage
5) Dr. Octopus
6) Kraven
7) Sandman
8) Kingpin
9) Green Goblin (H.O.)
10) Electro

In the end, these are just comic book characters, surely the real most dangerous enemy is JQ

• absorbing man
• morbius
• blackheart
• mephisto
• kraven
• carnage
• venom (duh)
• doctor octopus
• green goblin
• kingpin

Doc Ock eh?

The best 3 are Doc Ock, Green Goblin, and Venom.

1. Green Goblin/Norman Osborn
2. Carnage
3. Hobgoblin
4. Dr. Octopus
5. The Lizard
6. Sandman
7. Morlun
8. Venom
9. Rhino
10.Electro

Oh please the best was the dude that really beat him to a pulp and actually killed him before "the Other" showed up..

10. Electro - untapped potential
9. Rhino - same reason
8. Lizard - unpredictable and a source of random anger
7. Chameleon - I want to see him as a major threat because of his skills
6. Kraven - the ultimate hunter deserves more of a spotlight
5. Venom - he's more of a neutral force now, but he was a much deadlier Lizard in his heyday
4. Sandman - he's a shape-shifting monster
3. Hydro-man - much more deadlier than Sandman because of his composition; water is harder to get rid of than sand and it's much easier to find
2. Carnage - he's a convicted serial killer mixed with a symbiote that's more powerful than Venom
1. Norman Osbourne - he's a manipulative b****** with an Iron Man suit

Peter Parker's most dangerous enemy is his Spider-Man persona. Who's screwed Peter Parker over the most? Spider-Man. Who has caused Peter's friends and family the most heartache? Spider-Man. Who brought Venom to Earth? Spider-Man. Who was responsible for The Clone Saga? Spider-Man. Don't you see? Everyone else is second rate in comparison to Spider-Man's truly greatest enemy...HIMSELF.

10. Mr.Negative

In order from those who have caused the most harm to Peter

1.Morlun

1.Carnage He's as psychotic, and insane as the Joker. One that thrives on murder, and chaos. He's so dangerous that Spider Man has had to team up with one of his major enemies Venom (Eddie Brock). Had the Big Apple in major trouble with Maximum Carnage. His insanity is way more dangerous than Green Goblin.
2.Green Goblin The master of being nasty, and one of Spider Man's most infamous foes. He's made his goal to destroy Spider Man's life, and has enjoyed doing that including having Gwen Stacy killed, and using Spider Man's known secret identity to torture him. Norman wants to make Peter Parkers a life a living hell mainly because he doesn't like Peter at all.
3.Venom (Eddie Brock) The antithesis of Spider Man that has the delusional belief he's good, and Spider Man is the villain. Basically seems like Spidey on steroids, knows who Spidey is, and can block his spider sense. Another psychopath that made it his goal to destroy Spider Man.
4.The Kingpin Basically seems like a bad version of the American Dream. He's shrewd, calculating, nefarious, and has been causing trouble for the Amazing Spider Man, and Man without Fear Daredevil. With nearly unlimited resources he's been a thorn in Spidey's side. and nearly killed him.
5.Doctor Octopus He's the Mad Scientist, and has used his brillance for evil. He defeated Spidey in his first appearnce, and the wall crawler was considering giving up until Human encouraged not to. His four tentacles are more than enough to give Spidey plenty of trouble which they have done.
6.The Lizard One of Spidey's friends Curt Connors is the savage beast known as the Lizard. The Dr.Jekel Mr.Hyde personality make him dangerous to Peter, and all others near Curt Connors. Given the webhead a run for his money.
7. Mysterio What better way to discredit Spider Man than to frame him. With a hatred for Spider Man he's been able to give the webhead plenty of problems despite no super powers. He even fooled Spidey through a illusion that senior citizens were some of his most dangerous foes.
8. The Jackal Another case of brillance being used for evil rather than good, and a scientist gone mad. He manage to mislead the Punisher to kill his hated foe Spider Man, and like the Green Goblin he is aimed at destroying Spider Man. Add in he cloned Spidey, and Gwen Stacy.
9. Scorpion He wants to destroy Spider Man, and J Jonah Jameson. Add in he's insane. To cross the Scoropion is to risk getting stinged. He's going crazy because he can't get his former life as a normal human being back, lost his sanity, and won't rest until his wisecracking nemesis is dead Spidey, along with Jameson.
10. Morlun He's able to tell where Spider Man is, and sucks the energy from mutants to survive. Tore out Spidey's eye then ate it, and then broke Mary Jane's arm.

I would love to put Shocker on this list but due to be a super power bank robber, and mostly rational he hasn't caused Spidey grief, and has harmed more of people he robs than Spidey. Add in Spidey is not afraid of him at all with his wisecracks looking like a quilt.

lol is the worst Parker chief, just to put him in trouble by his neurasthenic temperament or may be even one day will end up hanging him ^^

Carnage  and Venom have had their weakness discovered so they are not as deadly anymore. And Doc Oc is dying.

1 The New Sandman
2 Osborne
3 The Kravens
4  King Pin   
5 The new Electro
6 His roomate Michelle (joke)
7 In time Morrbius because Peter will age and Morbius won't
8 Hydroman (good thing he's not smart)
9 Tombstone
10 Aunt May (by him walking in on her having sex which nearly killed him)
