Isn't that what a b moveset is about? Their signature moves? Look at Link. Spinning Attack, Bomb, Boomerang, Bow
Samus. Bomb, Missile, Screw Attack, Charge Shot.
The only characters that don't have "obvious" b moves are those who didn't have many moves in their own games. Like Pit for example, all he did was fire his bow in Kid Icarus. I think my moveset is justified.
