The Incredible Hulk Coaster® is in Marvel Super Hero Island® in Universal's Islands of Adventure®. This roller coaster isn't for beginners. In just two seconds, you're accelerated from zero to 40 mph, directly into a weightless zero gravity state as you're upside down. The coaster is green like Hulk, and that's the only thing people see from the ground as the blur of the cars whoosh by. Height requirement: 54 inches. Thrill ride.
