The sad part when Falco's Melee/Brawl Bair was actually a real kick... It's called a flying back kick. Y'know who else has that move? Sheik, except hers is more stylized. Really wished they could patch in Falco's old Bair with the same knockback and damage for the back hit, but make the front hit a hit that can't kill, but is more like the weak hits of Mario, Luigi, Fox, Sheik, and Link's Nair. A real-life RAR Bair.
And Dash Attack, kind of wished it looked the part of being a slow kick when right now, it doesn't; it's just a flying side kick where you lift your legs up after running. That shouldn't be a slow move compared to the flying back kick gif above, Yoshi's current Dash Attack, or Ike's where he has to heave a heavy sword and perform an uppercut. If anything, it could look like the flying reverse side kick - basically Falco's current Bair -
that Dante does in this cutscene. Hell, Fox already has two of the same moves: Nair and Dash Attack; Nair is just an aerial version of Dash Attack and vice versa. The turnaround part can be used to justify the 8 frames of startup; 4 to turn and 4 to kick unlike what it means to take 8 frames to lift you legs up as Falco's current Dash Attack is.
Welp, done complaining, but thing about Falco is that's got a solid set of moves right now, but some things could be tweaked and he would be much stronger than he is now. Grab in particular which doesn't make sense for a slowish character like him to take an Up Smash's startup to (do a standing) grab things while really speedy characters like Fox and Roy can immediately grab while standing.
