Cho vs Banner - on equal prep/tech footing
just as the title says - EQUAL TECH/PREP.
Banner and Cho both think the other's gone rogue. Banner thinks it's his responsibility to bring Cho down (in order to save him, NO HULK SMASH!).
Cho realises that he has to go for the kill though, because he knows/fears the kind of damage a really unhinged Hulk/Banner might do... so he's going for the kill but as a "last resort".
fight takes place in an alternate reality where EVERYTHING in the landscape is made from prawns (except for Cho & Banner and their Banner/Cho-augmented-Tech).
