But where it feels unfair to me is if at Fullscreen against Peacock I press just forward, see the super flash of Argus and jerk the D-Pad Back to block it works. But against Robo in the same situation it doesn't.
You
can't block Cat Scratch Fever / SSJ / Death Crawl / Dynamo post flash, but you
can block Gigantic Arm and BFF post flash.
You
can block Feral Edge, Gregor, Scalpels post flash (and counter super), but you
can't block or counter super Thresher post flash.
You
can jump Daisy pusher post flash, but you
can't jump post flash vs Showstopper.
You
can block SSJ post flash if Big Band has Undizzy when he does it, like most level 1's, but you
can't block level 3's post flash if they have Undizzy.
There's a bunch of exceptions and if you want to change something about Robo-Fortune and turn her cool neutral Cannon tool into nothing more than a combo ender or 990 chip tool, I'd prefer if you had a better reason than "It doesn't work like that for the other thing."
With the video you posted that was all just how you punish after block or for pbgc. What are the options for punishing Beam Super at fullscreen during/after super flash?
From the super flash, opponent enters hitstop until the first active frame, so you can't input anything. (Like
almost every other level 1)
You can trade with it if you had a button out already because Cannon is not invincible on first active frame, but besides that you don't punish it immediately after the super flash if that's what you mean?
Like you don't see point blank Gregor get stuffed by counter super Dynamo, that's Vanilla and SDE.
