So let me rephrase what I said earlier. I will admit my argument that he would be heavy doesn't have much weight to it (HA), but I do feel like he most certainly wouldn't constantly be flying. I don't know whether that's what some people are thinking or what...
Basically, having Ridley constantly flying would be troublesome. He would have to be able to walk on the ground to work by the rules of Smash. He has to be able to be KO'd in all directions, meaning he would have to be able to hit the ground, etc... I might not be making a whole lot of sense to people but it makes sense to me.
I may be completely misunderstanding what people think Ridley will be capable of. But from what I've read, it comes across that people think Ridley will always be flying like he does in the video. That wouldn't make sense. What if he gets smashed off the stage, but not KO'd? Can he just fly at the bottom of the stage until somebody actually KO's him? He would have to play by the rules of Smash, meaning he would have to have a ground game. Which would then come full circle, meaning he couldn't always be flying gameplay wise.
Again, this makes sense to me, but it might not make any sense to anybody else because I'm trying to put together my thoughts on the whole concept. There would have to be some sort of way to adjust his height off of the stage.
Let me try to explain this...Say he is always flying. So he starts at the bottom of the stage at the start of the match. Can he adjust the height of his flight on the fly? Because the way that video clip looks, he looks as if he's sticking to one height in the duration of the flight. Meaning, if he HAD jumped off of a platform prior to that clip of him grabbing Pikachu, he would have to land eventually instead of continuing to fly. Simply put, the height that he would be at seems strange for a playable character who would be constantly flying to stay at.
I guess I need somebody to explain to me how the flying would work, because right now to me it seems too crazy to work lol. Hence the confusion that you probably have from reading this post.
