Thanks! :D It's nice to see peeps acknowledging the perspective of others.
I agree it's easier to picture Girahim bringing something original to the table - at least in terms of fighting style, because I think in terms of character and aesthetic Tetra is one of the best potential newcomers. But I felt much the same for Skull Kid, Vaati and (especially) Zant - all fantastic potential styles, but all ultimately one-shot villains.
Not to say Sakurai should ever be judged on past decisions. But Tetra has been in 4 games if you count the WW remake, one of which she starred in - the only Zelda spin-off bar Tingle. And I just can't get over how fantastic an addition a little girl pirate would be to the colourful cast
(as an aside, your sig is basically my wishlist minus Tetra :D )
