I have a feeling that this has been done to death, but this battle is only between 7 members. I have a debate in my English class, and my teacher is letting us do the Avengers vs. the Justice League (I know, it's awesome, lol). For the purpose of the debate, we're having rounds of fighting. We roughly sorted our heroes from weakest to strongest and the weakest fight first. The surviving fighter goes in to the next round. ex: thor kills wonder woman, so he advances to the next round (yes, it would be 2v1).
Like I said, there are 7 heroes per side, hence 7 rounds. All fights are just in a random city on Earth, with no BFR. Each character has on his/her suit if they have one, but it's a random encounter.
I honestly don't read comic books, so go easy on me lol. Just please go in-depth as to why each hero would win a round, because we're supposed to be debating it, and I can't just reference a person on a comic book forum site. And just to let you know, I'm debating for the Avengers side. Lastly, all characters are out to kill. So Thor/Superman won't hold back at the beginning of the fight, Batman will kill people, etc.
Round 1: Ant-man vs. Aquaman
Round 2: The Wasp vs. Batman
Round 3: Hawkeye vs. The Flash
Round 4: Captain America vs. Martian Manhunter
Round 5: Iron Man vs. Green Lantern (Hal Jordan)
Round 6: Hulk vs. Wonder Woman
Round 7: Thor vs. Superman
Okay, so say Ant-man wins the first round, he would be able to help The Wasp in the next fight. Then if they both killed Batman, it would be The Wasp, Ant-man, and Hawkeye against The Flash. As a final note, what my friend and I were planning on doing to make it so it wasn't like 5 of The Justice League against Hulk, was have Iron Man call all 42 of his suits, like he did in Iron Man 3 (the movie). Just please go in to a lot of detail about each round, so I can really debate it. Oh, and I realize that the Avengers are kind of major under dogs in this, but thanks in advance :)
