1. Wolverine - lures Wolvie into a trap which uses electromagnets to create a powerful magnetic containment field to suspend him harmlessly in the air. While Wolverine flails helplessly about with nothing to cut or gain any leverage with, Batman introduces superheated plasma into the field, eventually burning every molecule of Wolverine's body into ash.
Batman switches off the electromagnet and collects the adamantium skeleton for his Batcave trophy collection.
2. Hulk - hypnotizes him back into Banner then punches his lights out.
3. Thor - adamantium bullet to the head.
4. Spider-Man - uses an electronic device that negates spider-sense then gasses him.
5.Ms.Marvel - tracks her to her home then waits and gasses her while she is sleeping, then puts a neural-nullifier device on her.
6. Iron Man - probably some hacking or other, or device which shuts down the armor. Nothing plenty of other guys haven't managed to do. Or ruins Stark financially and drives him back to alcoholism.
7.Cap. America - car bomb / motorcycle bomb.
