For those who didn't follow it in DSL, pummel has IASA frames, when the knee hits.
This brought up some questions, so I'll answer them...
Nicely done, FD, but as you said, this is a MYTHBUSTA topic. I'm a HUGE purveyor of pummeling and I have it down to a science. That said, I had no idea that Ganon's pummel had IASA frames! Is this kind of like how Samus can do hyper speed b*tch slapping?
Yes, I believe it works under the same 'rule'... It seems that every pummel has IASA frames when the hand/knee/whatever hits. That's where I got the idea from.
Note: when Samus b*tch slaps super fast, she doesn't get a refreshed slot on her stale move list for EACH slap. I'm not sure of the specifics as I am just relaying information from MOM as I can best remember it, but I'd really appreciate it if you could look into this, FD.
Samus' and Wolf's pummel seem to be alike, so I believe I can answer this.
With Wolf, he hits so fast that you just HAVE to slow down. It seems that not every hit registers, it won't do damage. Some effects still have the "hit" registration, and therefore still refresh moves, even though they won't do damage. Example: G&W's uair and Ganon's utilt wind effect.
However, it seems that the pummels do not register whatsoever... Meaning, it won't refresh stale moves.
I do not believe Ganondorf has to worry from this, since his pummel isn't crazy fast like Samus' or Wolf's (those are just unreal when you abuse them at their full speed). Every hit does damage, so they must've registered as a hit and therefore refresh moves. I'll test this a little bit more though, but expect it to refresh your moves.
