Oh please. There's plenty of Zelda characters to choose from. I'd argue Shiek isn't that important but it doesn't matter does it? Tink isn't either, but that's largely due to him being a clone.
There's main game/ reccuring ones:
Impa - yea she has different looks all the time and sometimes young other times old, but it's not like Zelda or Falcondorf ever had different looks in Smash than the TP one . Very significant and important character that I can't believe
Masked Link - Yes, another Link. At least this would be vastly more unique. Have his specials be completely new aside from maybe the bow and spin attack, but change those as well slightly so for example, make his arrows slower and have fire like Young Link.(Masked is pretty much Young link but with a MUCH better name).
For standard attacks.....probably best to have new ones too. Similar to Young Link in Hyrule Warriors, he would use his sword with two hands. The PERFECT evolution of Tink/Yink. (I'd like Tink to stay, just to rep the cel-shaded Zelda's.
Ganondorf - Would kinda count if they made a moveset worthy of the dark lord. **** those Falcon moves and give him actual Ganondorf/Ganon moves!!!!!! Or at the very list.......change his specials and make him a semi-clone.
Then there's the Secondary/Supporting characters.....
- Ghirahim
- Midna
- Twili Midna
- Fi...
HEY! LISTEN!
- Vaati
- Hilda (better than Tetra!)
- Great Fairy - pretty iconic and just imagine the Powers.
- Cia
- Lana
Granted, most will never join but shows the selection.
