Man of Tomorrow
Reveal trailers glorify chars!
They show off the movelist, basic combos/setups, and their intro/fatality. You can just as easily glorify them yourself. On top of that reveal trailers can make a character seem "not good" until you learn exactly what they can do.
Edit: Make no mistake, I like reveal trailers, I just don't see the need for every character to be known pre-release.
