This is the situation
Lex Luthor & Loki have joined forces to destroy there enemies.
They devise a plan where the supers will meet in a remote part of the city, & Loki will use a Enchantment to make both sides BLOODTHIRSTY(LET IT HAPPEN). In this case IRONMAN knows all about the DC characters & BATMAN knows all about the marvel characters. They have no time for prep. Because of this BATMAN has not shared anything on the opponent and neither has IRONMAN This is a fight to the death. They can use anything they have and can ONLY call ONE person for backup (Marvel-Blue Marvel) (DC-Captain Marvel). But the person can only be called when one person on there team has died. The characters don't have to fight 1 person specifically, the characters wont hurt anyone on there own team!
Also rank the characters in the order they would die and who would ultimately be victorious!
DC: ALL CHARACTERS ARE PRE-52
MARVEL: WOLVERINE HAS HEALING FACTOR
