Dtilt? Why do you even have interest in that move?
Dtilt combos into jab/grab on 0-10% or something, after that it's pretty much the same position as the dair bounce, just a lil higher (depending on staling ofc)
D-tilt's trajectory basically puts ROB in the worst position possible. Above and right in front of the enemy. No matter waht ROB does, if you stand in this position and shield he can do absolutely nothing.
Seriously, his best option is to reverse gyro cancel slowfall bair spotdodge.
That's to
land.
If d-tilt could somehow be used extensively in this matchup, I could see it easily becoming in falcos favor. ROB is easily punished from this position, but has many tricks to get to the ground if you over commit from far away.
I feel like Falco's lasers are more of a parlor trick in this matchup. You can't rely on them, and Falco hurts in terms of having safe approach options without a good laser opening. D-tilt is perfect vs. ROB though, except for the fact that it sucks in every fashion other than trajectory.
can rob outcamp falco?
can rob approach falco?
can rob avoid falcos kill moves?
yes yes and yes.
If ROB has a gyro in his hand, the matchup is in his favor. He can glide toss into anything he wants as you jump if he spaces himself correctly. Other than that, he has to (painstakingly) shield the lasers properly and not get janked by a tricky Falco approach out of the blue. ROB's defensive options are some of the best in the game. ROB can also laser out of a powershield if you're double lasering and hit you, but I found a Falco randomly stopping to just standing laser can really throw a wrench in projectile wars. Depending on the stage ROB can do some impressive projectile stuff, but on the stages you are thinking of (like BF, FD, SV, etc.), ROB has no real option other than glide toss or painstakingly slow walking and a mind to react.
ROB's approach on Falco is merely the limiting of Falco's lasers. If he can get within range to where Falco needs to over-b (free fully charged laser/gyro) or go off stage, ROB can often force the Falco into an action that is not profitable in the long term for Falco. ROB can punish Falco's over-b fairly easily for massive damage (20%?!) on reaction and any mistake on Falco's part can lead to a heavy edgeguarding string.
As for avoiding kill moves, yeah. ROB's most trouble with Falco will come from a double bair if ROB is coming in from above. If memory serves me correctly, Falco's u-smash's hitbox stays out long enough to where it's easy to time through a ROB spot dodge but I'm not entirely sure...
most of the stuff you're saying about the MU is spot on and Falco does have a lot of options and can most certainly win this MU. However, jab is practically useless unless the ROB messes up as ROB should be staying at his f-tilt length... which outranges both your jab and f-tilt.
The trick for Falco, from what I've seen, is to get ROB in the air and punish him on landing as often as possible. If Falco focuses on dealing damage when edgeguarding (lasers, bair, nair, etc.) rather than getting KOs, it will force ROB to take more risks on teh ground that he normally would not take. ROB and Falco can both punish ANY aerial on reaction, making this a game of grabs and long range tilts.
