Batman (comic version with no PIS) gets a week of prep with standard bat gadgets, no insider suit.
Blackhawk can: Runs fast, accelerates fast as a car.
Jumps ten ft high.
Throw Shockarangs (look like boomerangs but they don't come back) thattransform into concussive shockwaves once they get within 6 inches of any surface. She can create and throw these at will.
She is immune to bullets because of a deflector forcefield that protects against things going at that speed. A batarang or a punch could get through.
She is strong /durable enough to lift ten tons.
Battle is here: Asgardians generally don't like Batman because he keeps on saying "I'm Batman..." expecting them to cower in fear. They think he's a fool with no powers.
If Batman clears this he goes up against Loki (movie version)
