Bowser's Ledgehop Aerial Uspecial Regrab

Bowser is able to ledgehop and perform and aerial attack, then Uspecial back up to grab ledge with four of his five aerial attacks (all except Dair). He is able to do all of these with full intangibility on the active frames of these attacks. Being able to perform this is crucial not only to fully maximize his edgeguarding game from their use, but also for building general ledge comfortability so that you don't die from silly missed inputs.

The way the input works is first you go through the mandatory cliffcatch frames at the beginning of a cycle, then do one frame of falling from the ledge, followed by one frame of empty doublejumping before you input your aerial. After your aerial of choice's animation is complete, you can perform a Uspecial to get back to ledge. The earliest you can input an Uspecial is obviously dependent on move choice-- Here is the total frame count for each of Bowser's aerial attacks:

Uair: 47
Bair: 49
Fair: 45
Nair: 49
Dair: 79

(A fun thing to note is that with Uair and Fair, you're actually able to land on the stage during the Uspecial's animation if you do the sequence fast enough)

The latest you're able to perform an Uspecial assuming you doublejumped as quickly as possible after leaving the ledge is the 66th frame of the sequence. It is important to note that due to the nature of this tech, the frame data isn't affected at all by your horiztonal aerial drift. Due to this, you are able to fully drift in whatever direction you choose, and still make it back to the stage. These are incredibly tight windows for your inputs, and so I would highly recommend using claw grip to maximize your ability to perform them consistently.
