The following is how JLA vs Avengers: The Season 2 Finale will go:
EPIC BAT BATTLES OF HISTORY!
THE INCREDIBLE HULK!
How it will flow: Cap does his lines like Leonardo da Vinci (as many lines as da Vinci has, everybody else has (it's that long))
Then passes the mic to Iron Man, then to Thor, then Hulk, then Black Widow, then Hawkeye, then Quicksilver, then Scarlet Witch, then Spiderman, not Fury yet
Then Superman blasts in, basically destroying The Avengers then Wonder Woman comes in and raps against Black Widow and Thor. Then The Dark Knight makes Superman and Wonder Woman disappear after they are done then Flash appears and raps.
Cap interrupts Flash and raps 2 lines. Then Flash finishes then runs having Martian Manhunter come in. He flows some awesome raps destroying Iron Man. Then Aquaman makes an ocean and a record scratch happens. Cap is now talking to Aquaman like he is a baby like the others. Aquaman makes the water disappear destroying Cap, then GL comes in with a green glow on everything, while Batman is doing something in the background. He comes in after GL's last line in a Dark Knight voice.
He raps 5 more lines than da Vinci ever did.
Hawkman, Green Arrow, and Cyborg rap together. Hawkman raps first, then Arrow, then Cyborg.
Nick Fury gets in the battle and raps destroying GL
GL raps 2 more lines
Nick Fury finishes then Iron Man and Cap get in front of Nick Fury and he disappears having Iron Man and Cap rap 16 lines total together. The whole JLA says something which makes Tony and Cap turn into Thor and The Hulk. Superman destroyes Hulk and Thor. Thor yells "BY THE POWER OF THE HAMME...". Hulk punches Thor leaving him flying like how he did in The Avengers, which makes them morph together into Hawkeye for the Avengers' last line. The JLA rap together 6 lines by themselves destroying the Avengers as a whole. Then Flash has the final line. All of the comments for JLA vs Avengers appear filling up the whole screen fading away into a Season 3 sneak peek with Captain Falcon, who will be appearing in the season.
