Two things about Falcon's side taunt that I was reminded about while playing Minus with friends tonight, and testing things on my own:
1.) It already has a cancel window at the very end of it; in fact, all of Falcon's taunts do, except left-facing down taunt. You can cancel them into any other move, including themselves. However, the window of opportunity for this is very small -- only a few frames. Side taunt cannot be cancelled until after Falcon has finished saying "Come on" and completed his hand gesture.
2.) The "Falcon Force", or the little pull, actually does have a use, although it's only a comedic one: If your opponent's shield is broken or they're otherwise stunned, you can pull them right up to you, taunt again, and PAWNCH them.
I also found out that a slow-mo air-to-ground instant PAWNCH is awesome when you land one.
It's basically a regular Falcon Punch in that it has the mini hitboxes as well as the final one, but Falcon doesn't warn the foe with "FALCON..." and it feels great when you KO with it.
Anyhow, those first two things make me no longer want the Falcon Force to be removed from side taunt. If you could make the pull effect only happen if side taunt is held (not tapped), that would be ideal.
I'd like to see the cancel window at the end of side taunt open at frame 90 instead of frame 99.. It currently opens right as Falcon begins retracting his arm (frame 99). Please widen the window to the frame in which his hand stops moving after the second wrist motion (frame 90).
The "Falcon Force" pull effect's hitbox should be widened on Falcon's end, just a little. The pull effect won't work on an opponent that is just barely out of Falcon's grab range.
That is all I'll ask for Falcon's side taunt.
(I still think giving it super armor would be great too, but no one else agrees with that...)
Reverting Falcon's side taunt back to vBrawl actually makes it even worse than it is now. At least now it's funny to use when you break someone's shield.
As for up taunt, how about just making Falcon say the quiet "Yess" if it's not cancelled into Falcon's secret taunt? Perhaps he should only say that if up taunt is held, not tapped...
That's about as minimal as it gets for suggested changes.
