I'm not too sure if I really cared about the tagline in Ridley's potential trailer. Though most of them are usually puns, except for Mega Man, but he's awesome enough without one.
I would go with "Ridley Swoops in" or "Ridley Soars into the battle!" Nothing too fancy. Though I guess I'm not clever enough to do that.
Heck, I'm not even expecting a trailer at all. And if we do get one, there's a real good chance it's not for Ridley. As much as I would like it to be. I'm excepting that we'll have to wait for the game to drop in Japan before we really, really, know what Ridley's suppose to do in this game.
As they say, expect the worst, hope for the best. I suggest doing the same ladies and gentlemen.
