Mortal Kombat announcer to Batman: FINISH HIM! Batman to Mortal Kombat announcer: No, I don't kill people. Mortal Kombat announcer to Batman: WHAT?!?!?! Batman to Spiderman: Same time next week? Spiderman to Batman: Sure! They leave.
Spider-Man's main ability is shoot webs and crawl along walls. He shoots Batman witth a web, he uses a batarang to cut it. He tries to climb up walls he throws a batarang or hits him with one of those nets. Batman can simply counter anything Spider-Man has.
