Flash 10/10
Heres how kiddy winks....
Flash absorbs all of Hulks kinetic motion , effectively reducing him to a non-moving lump. This trumps any 'Hulk will smash the battelfild' theories straight away. Now that Hulk is nothing more then garden ornament Flash can do one of three things.
1. Simply vibrate through the Hulk , mere seconds later the green Goliath is reduced to a large pile of goop spread across the landscape. Even with a healing factor there's very little chance of Hulk getting back up from that.
2. Dwarf Star Punch
3. Drag him into the speed force, although this ones a little over the top. Kinda like killing a fly with a shotgun....
