At E3 Treehouse Event we get to see a selection screen with up to 9 playable characters. We already know of Link, Zelda, Impa and Midna.

Who are the other 5?

I can easily see Ganon/Ganondorf joining.

Majora just  out of hype could be possible too.

Other than that the only thing i can think are the Zora/Goron forms of link, or an actual Zora/Goron. Oni Link maybe, but that just sounds like a wet dream.

Tingle

Fierce Diety Link would be sweet...
I could totally see Tingle making the roster, for better or for worse...
I would love to see Captain Linebeck make it but, if there are indeed only nine characters, I think his chances are slim at best...

Link, Zelda, Impa, Midna, Ganondorf, Zora, Goron, Yuga, Ghirahim, Hilda, Shia (Uncorrupted as per cover art) and corrupted versions. Donno who else.

Edit: was it confirmed to be nine? If so, Link, Zelda, Impa, Midna, Shia, Ghirahim, Ganondorf, Zora, Goron.

Not, it is not confirmed yet. Just speculation.

Tingle, The King of Hyrule, Ruto, Saria and Darunia.

that much? thats actually pretty badass. Probably pick this up when i get a WIi U eventually.

I would pay money for tingle dlc to this game or pretty much any game. Imagine playing arkham knight and all of a sudden bam your tingle taking down everyone in Gotham.

1. Link
2. Zelda
3. Impa
4. Midna
5. Ganondorf
6. Cia
7. Wizro
8. Valga
9. Blue-haired box art character

It's possible that's all of them. A note: during the Treehouse stream, someone confirmed that at least half the playable cast is female, and 5 of these 9 are female.

I'd bet on a few more than 9. Wouldn't be surprised to see Nabooru in there.

I hope the roster is larger than 9 characters. Pretty small for a Dynasty Warriors game.
