so you're placing batman in MU new york with full knowledge of spider-man's rogues gallery then? how would he beat the hell out of lizard or rhino? rhino has gone toe to toe with thing and hulk and is still walking around, lizard is way faster than batman...... but it's conceivable bat could win..... it just wouldn't be through fighting, he'd need to use some trick
green goblin is very intelligent, has a lot of weapons and is, again, way faster and stronger than batman..... shocker is a bit of a joke...... IF he knows about symbiotes the sonics could work, but they have become more and more capable of withstanding sonic attacks and could wreck whatever weapon he uses, scorpion is pretty dumb and, even though he is, AGAIN, stronger and faster, i can see him losing, mysterio is very tricky and would disoriantate the hell out of batman, that'd be more interesting than scorpion's fight, kraven used to be tough, not so much now that he's dead, ock could take him, but he is just an average man when you get past the arms, so i wouldn't put a lot of money on him
kingpin....... it's possible batman could take down some of kingpins operations, but i doubt he'd get a decisive victory over him anytime soon, kingpin almost always walks away spotless, and he's definately able to hold his own in a fist fight with batman
i think norman osbourn could make his life very difficult
