Umm, I am not a batman fanboy. In fact, I hate him and superman completely. I think they are far overdone in every aspect. I am saying that as long as batman has preparation, he will win. Don't be so noob as just say "He said that cause he's a fanboy". I read DC and Marvel, sure I prefer DC more. I really dislike little boys like you who can't argue and just say "ZmG he's a fanboy". Batman is the greatest detective in the world. And yea, he does do some really bs stuff a lot of the time.
If Tony was on the first strike, then he would win. If batman knew what was coming, he would win. Don't get me wrong, I only play favorites when Flash is around. Because of the knowledge and level of logical inference that batman has, while it is completely overdone and more metahuman than most "12th level intellects", he would win with the preparation. If Tony just woke up and said "ima kill batman" and ganked him on the street, Tony would win.
Don't sit here and say "fanboy" cause you cant argue.
