The Avengers can destroy the Justice League

We did not establish any kind of prep time. I don't concede to the fact that if they face each other with no prep time that the Avengers would lose. Also it is not the best thing to say you won when we are still debating please let other people to vote and decide. I am going to quote you because you said " Batman creates contingency plans for the JL, all of whom have insane amounts of power in their own right, that could be carried out even by someone without super powers." That means that even Black Widow could do it and it would not be a challenge to retrieve the contingency plans. Iron Man is smarter than Batman because he is a genius in engineering and computer science just to name a few while Batman is mostly focusing on being a detective to solve minor crimes in one city compared to Iron man. Iron man does not just settle in fighting crime in one city hiding in the shadows. Iron man created Jarvis on his side while Batman has Alfred. Jarvis is obviously smarter than Alfred in all aspects. This is why it is easy for Iron Man to get the contingency plans from the bat cave. While fighting Batman Tony does not have to be there in battle he can control his suits from where ever he is at. He can send multiple suits to fight Batman at once for fun. Batman has to physically be there or he will not win the fight. While Tony is somewhere else he can access Batman computer or blow up his bat cave with his other suits for fun. This is not a challenge for Tony because he is smarter and more resourceful. Your argument on Iron man making plans for the other Avengers if they went rogue is useless. Iron man is the smartest in the Avengers but there is no need to make contingency plans. Shield is the one who made the contingency plans in case if any of them went rogue. The Avengers movies are based from the comics Avengers 1-4 and in the movies Nick Fury is putting together contingency plans for Thor while they already have plans for the others. Iron man does not have to worry about plans because he already made suits for the Avengers. In Iron Man 3 Iron man called his suit in his sleep to protect him without trying which are based off the comics Extremis 1-4. Even if the battle had prep time or not Tony can still access the computer because he does not have to being battle and even if he was in battle he can tell Jarvis to go through his computer by hacking Batman communications with Alfred which would be traced back to the bat cave and that is where the computer is at. Iron man can takes hits my Thor and his hammer made from a dying sun which has enough strength to block punches from Hulk and to fight Thanos. Once Tony has the contingency plans then it is game over because Batman knows the plans will work. Tony is also not afraid to kill because he makes weapons for the military and is known to kill in the comics. For your scenario of flash cutting throats does not work for the Flash. He is a forensic scientist which means he does not kill. The Avengers are not afraid to kill because Cap fought in WW2, Black Widow is an assassin, Hulk smashes, Thor is a warrior, Hawkeye has bow and arrows and Scarlet Witch was born into war. Nothing is holding back the Avengers while the Justice League is against killing. This gives the Avengers the advantage. The battle will not last long enough for Batman to make plans for the Avengers. Just to clarify the fight between Thor and Superman, the life span of Thor is about 5000 years while superman has a life span of an average human. Thor has thousands of years of fighting experience and he loves to fight in battle. He always looks for new challenges. On the other hand superman is young and does not have as much of combat experience like Thor does.Thor will be able to predict Supermans moves and have fun doing it. http://marvel.wikia.com...(Earth-616) https://www.quora.com...
