Deity apologzies if this is old...but in all the time he's lurked and skimmed, he hasn't seen a mention of this.
We all know that if you Wizkick Ganon toward the ledge at just the right distance, it cancels and lets him do an aerial. Quite some time ago, Deity accidentally did something similar, but he did it in the middle of the stage. It isn't random and works on most stages as far as he knows, but it's rather situational. Any place with a level ledge will do.
Just roll backward against the edge of the stage then hit DownB. Ganondorf Wizkicks toward the center of the stage, but doesn't have his normal ending lag - he rolls to a stop as though you Wizkicked off the ledge. This puts him into the air for just an instant instead of on the floor. The only use Deity has been able to give to this is to pivot-Murder Choke a spotdodger, or just use a normal Choke on someone who rolled away. It doesn't seem very well known, and it comes out very quickly so it usually hits. Hitting DownB again does an automatic Murder Quake, but it's application would be extremely situational, even against a pants-on-head ******** opponent.
Deity doesn't know if any of Ganon's aerials come out fast enough for a hitbox to come up before he hits the ground (MAYBE Bair), but maybe someone can make something of this~
