This sounds like a conversation that's happened before.
Apparently it's going to keep going until Ganondorf gets that damned ball.
Yes. In all those games and more, he or a version of him uses the Dead Man Volley. How you can pretend it's not iconic is beyond me.
Besides, it's not like this single special move would prevent him from punching or kicking. There is the normal and Smash attacks for that.
You keep bringing the Dead Man's Volley up, so let's see if Ganon AND Ganondorf unambiguously uses it enough to be an iconic move. For the sake of the argument, we can discount any time when it's Phantom Ganon, an imitation of Ganon, or Ganon being possessed.
- Agahnim, who is Ganon's alter-ego (bunshin in the Japanese version) is the originator of the technique in ALttP.
- Ganondorf himself uses it in OoT. No frills like disguising himself like Agahnim or possessing Zelda here.
- Ganon uses it while possessing Zelda's empty body in TP. It's ambiguous whether Ganon is using his power or Zelda's power to do so, though.
Okay, so if we count Ganon being in disguise or possessing someone else, yes, that's three times, and I subscribe to the idea that three's a pattern, so I suppose you can count it as an iconic move for Ganondorf.
That said, that's just ONE projectile. One move can hardly define a whole character. Especially when we're talking about a character whose abilities are widely divergent with every appearance:
Here's the thing: Both Ganondorf and Ganon fight very differently in nearly all of their appearances. In the 3D games alone he goes from floating mage with super strength, to beast with two giant swords, to acrobatic samurai with two small swords, to possessing Zelda with both his and her powers, to a giant quadrupedal boar, to a horse rider summoning phantoms, to a straight longsword fencer, to a heavily armed cyborg, to an even bigger quadrupedal boar.
Besides, a lot of characters, especially the 64-Brawl heavies, don't have their iconic projectiles, and no one raises a stink about them:
- : Doesn't throw barrels.
- : While he has his Fire Breath, it's effectively a rapid jab instead of the long-range fireball he uses more often.
- : LOST her Light Arrow after Smash 4 without it so much as being reworked as a projectile Smash or a special.
- : Doesn't have his ranged explosion granted by the Binding Blade.
- : Doesn't have his Ragnell beam.
As seen by these examples, sometimes character balance and individuality have to trump canonicity.
