If you did Meta Knight's up-B from the ground, you would just land back on the ground anyway since he does a full loop. The idea of freefalling after a grounded up-B is irrelevent to him, in much the same way it is irrelevent to, say, Link, who never leaves the ground during a Spin Attack. Also, he has a very personally-designed up-B in that he automatically glides at the end of it when he does it in the air. He still goes into freefall if he breaks the glide, but it still gives him a personal element of control without having to mess around with all this freefall stuff.some pictures too lol
this thread has come along nicely.... but.... WHAT ABOUT METAKNIGHT AND MARIO'S UP+B?!?!?!?!?!
Maybe only random characters have weird up+b's like that...
And we have never seen Mario do his up-B from the ground. I looked; he jumps a little before every one. And not imperceptibly like Samus did that one time; it's pretty obvious if you watch the high-res video and look closely. I'll bet he follows the same rules as Samus (whatever they may be).
