Meta Knights Dimensional Cape...I'll save the surprise for you to see yourself. http://www.youtube.com/watch?v=Wlhwdvf_U14#t=1m52s
Pikachu's moves (And probably everyone elses), cause no hitlag. http://www.youtube.com/watch?v=OZ4Dx331JDE#t=1m18s
Diddy's spike sends Sonic through a platform? http://www.youtube.com/watch?v=ols7ASPclbs#t=1m33s
(End of the video; "Diddy too good! Diddy for top tier!"...If only he knew)
I've also yet to see any of the supposed lag canceling that Gimpy insists existed. Supposedly if you fast fell an aerial it would cancel lag, but I've seen numerous fast fallen aerials and nothing has been canceled yet.
I'll post anything else I find.
