Test your supers you might have one fast enough to punish teleporting rush supers
Tired of being wide open? Well, you might not actually be wide open
I was doing some testing, mostly figuring out each characters buttons when I got to jeice and noticed his Full-Power Energy Wave super comes out incredibly fast and it starts right as the cutscene ends. So I had a thought, is it possible to use this super after my opponents teleport super and punish them for it? sure enough after setting up a match versus myself I was able to interrupt it every time. it stopped MUI goku, hit, gogeta (Z) and beast gohans teleport supers.
I feel a practical use case is charging to sparking to bait them into hitting you with the "wide open" and then popping your super punishing them for trying to punish you for charging lol.
I'll try to test more characters but if you notice someone has a super that starts the second the animation ends I'm willing to bet it can interrupt it. Gogeta SSGSS also seems to work if you use stardust blaster
Sorry if this is well known, just something I came across today
