Agree on Down B being the poof move as that's how the bomb is thrown, but those neutral Bs, I'd rather them be smash attacks, because each of those are chargeable. so..
Forward Smash (assuming the ones you mentioned are tilt/regular Smashes :
Goemon: Triple Ryu or Medal of Flame (Big flaming ryu)
Ebisumaru: Concrete Megaphone
Yae: Triple shot canon
Sasuke: .. umm.. was it big bomb or triple bomb
Edit: wait, that contradicts with your FB Ebisu move.. hmm
btw, we still need to figure tilt, crouch and air moves. taunts too.
ok ok, we need to spread each's move first.. soo, Goemon has
- Kiseru (bronze, silver, gold).
- chain kiseru
- flaming chain kiseru
- coin toss
- triple coin toss
- quintuple coin toss
- flaming big coin toss
- tiger rush
- superman
- super sayain
- spark shock
- kabuki dance
- spike yoyo
That's what I could think of for now (for Goemon), I'll be back for more.
We sure do need to put these in an organized list.. with images too.
Goemon has some ninjitsu attacks too (earthquake, thunder.. etc.), but I think including those would be too much.
