Well I did more "testing" (i kept upsmashing during ffa to see what it can and cannot do.
I've come to some conclusions. Firstly, I remember how everyone thought this move sucks because it has such low priority and everyone kept getting owned when hypen smashing it.(dashing into upsmash). This is a half truth.
I believe sonic has 3 stages in the smash. Standing about to jump, the act of spinning, then landing. While sonic is in the intial stage about to jump, he is completely vulnerable. However while spinning he has the priority. So if you do the hypen smash extremely early and slide into the enemy while spinning, it is possilble to avoid getting hit.
The weird thing is, sometimes the upsmash will trade hits with certain attacks, like ddd's upb landing which conflicts with invicibility, however I was c-sticking the smash. It is quite logical that sonic only becomes invincible when you charge the upsmash.
Regardless, there is still a lot of testing that should be done to confirm this or disprove it. Unfortunately I don't have the resources to do extensive testing.
