I wonder how customized movesets could affect the Homing Attack?
EDIT: Also this picture confirms his down taunt remains the breakdance.
That actually looks more like the charge up animation for his Up Smash, but the breakdance taunt was already seen in footage IIRC.
As for custom versions of the Homing Attack, I would want it to be something like:
-Default: Just like the Brawl one, but shorter start up and higher damage output, and mid ranged, as well as being a bit more accurate.
-Fast version: Little to no start up time, really accurate and has longest range. However, it hardly does any damage and does not make the opponent even flinch. It can be comboed out of on hit though, making it more of an effective chase tool.
-Strong version: Basically the Brawl version exactly, although maybe extend the charge time, but with near Falcon Punch levels of knockback, making it a good killing move. Most effective after having juggled the opponent into the air.
