The video here shows and explain it all.
How does silver surfer intercept me with his sp3?
Medusa's medium attack has already gone past the point of attack which it makes contact and yet he fires his sp3.
I am aware that medusa currently has animation issues but that is why i looked back and compare directly with one hit that makes contact.
you see the still frame at the exact point where my medium hit makes contact and causes damage to silver surfer.
you then see on the comb that he intercepts my medium attack has already gone well past that point in the animation when he launches his sp3.
