This could very likely be old or simply DI able, but i was using ZSS in training and i noticed that when spaced right you can Dsmash> dodge roll behind while paralyzed> Dsmash rinse repeat. The timing changes after 44% (probably not exactly that number) and APPEARED to be a lock until 77%, at which point i followed up with a SHFair. however since i was alone i couldn't test if it could be DI'd, and i don't know if someone else found this already. However it did work on the lvl 9 computer.
and yes this happens to be my second possible find... but the first one was old so i don't expect much of this =P.
