For those saying Hulk would win, you're forgetting that Aang makes friends so easily, it's ridiculous. Aang would befriend Bruce, so it would be very rare that he would 'Hulk' out. And for those times that he did? Aang is a mediator as the Avatar. He doesn't need to do anything but use airbending to avoid Hulk's attacks while he 'talks him down'.
Aang would win, no contest.
...Actually...
From what i've seen, Catholics promote idolatry and other things that go contrary to what the Bible teaches.
As for Mormons, they consider Joseph Smith to be higher than Christ, that "God" is not the only (nor the first) god in existence, and that someday they will become gods themselves and get their own planet to populate with their spirit children.
Ohhhh.... but they're Christian, clearly.
