Just thought I would let you guys know something I found out. So GDorf's Dash Attack has a hitbox that extends above, in front, and below him. Normally, the hitboxes below are useless, but recently, I discovered that if someone is hanging on the edge, and isn't invincible, a dash attack will spike them. My personal theory is that since GDorf's DA hits people up, they get hit up, hits the bottom of the stage, and fly back down. So far the only stage I have tested it on is Battlefield, but it may work on others.
