You get an anitmatter beam gun to fight avenger's hulk. I chose antimatter because antimatter has a rather violent, explosive reaction when interacting with normal matter. Anitmattter is the opposite of everything you know. It has a different charge or something like that. Anyway, given enough shots it should take down even the Hulk. There is NO reason why antimatter would'nt work. At best Hulk might be able to stave off a few shots, but not too many I surmise, (the beam is enclosed within a magnetic field so it won't react with anything until it hits a target) he would go down because he is only made of matter, even if he is a freak.
Location: New York. Your 200 ft away and have kawasaki motorcycle, on straight empty road. Hulk is bloodlusted and standing 200 ft away.
