Hulk happy!

Well for now anyway!

Hulk - Radiation-enhanced monster with devastating physical strength brought on by extreme anger

Thor- God with superhuman durability, speed and strength accompanied by powerful hammer

Wolverine - Mutant with enhanced quickness and physical strength with incredible claw-slashing ability.

Hawkeye - A real nice guy

Aren't they all too independent to be a team?

The Hulk is gonna collaborate with others?!

It's gotta be explained before I go see it.
