Man, I can't wait for the Pit version. Its hard for me to replace C.Falcon with Goku.

Click here to see  a vid I made with the beta.

also, i think that the only thing you need to fix is teh regular fs because it can be cancelled by throwing somethign in front. also, the fs used against kid buu, the bigger one, can be used more than once if damage is over 100

Oh man, as soon as a Pit version comes out, I'm downloading this. Especially if it has a soundpack.

Looks fantastic.

Any chance of making Cell, Frieza, or Broly? I'd love to see a good vertex for them. PSAs would be icing on the cake.

Just some quick recommendations:
Gliding - Razanak7 pulled it off with his Dark Link, so it may be possible on Goku. Might be easier for the Pit port since Pit already has gliding. As for the Glide itself, minimal speed and height , to simulate flying.
On Hit Cancel -

For DBZ-esque combos. Then Side-B could become a different move.
A faster Kamehameha (beam speed), but less damage in exchange. Not a whole lot faster, but it just feels a little too slow. Also would be nice to be able to store it like the Charge Beam (Though maybe give it a time limit).
A different Down-B (at least on the ground). Maybe a Counter type move, or a Dragon Fist-ish launcher.
An option to not hear "Over here!" every time he uses Up-B.
Maybe make the F-air fire three quick Ki blasts, and give the D-Air the spike.

When you finish up Goku's moveset, you think you could port it over Lucario? I like Captain Falcon too much to replace, and Goku is already kind of like Lucario (Similar moves, same voice actor). Even better if it would work for both the Goku model and Lucario (and vertex hacks).

Fairly sure Wolf's Japanese voice actor also did Vegeta in Japan, and Syntax Error did make a Vegeta Wolf texture, so that is something to consider when making Vegeta.

Lastly, if you're making Vegeta, I'd love to see a Nappa, to go with Vegeta. Could probably be done from Ganondorf.
