In keeping with the theme of the game, Slade and Shiva.

I want to play as all the assassins in multiplayer mode. Assassins battle one another while at the same time trying to kill batman and win the bounty.

That'd be awesome!

Lt. James Gordon.

His fighting skills are really on Display in Year One. I'd love to play as a younger Gordon, pretending all the bad guys are Detective Flass.

Alfred.

It is a prequel, I doubt any Robins or Batwomans or Huntresses will be making an appearance. I'm just happy with Deathstroke being there. I hope the Joker will become playable, like he was in PS3 Arkham Asylum. I do hope they extend or at least allude to the interesting subplots/easter eggs in Arkham City, such as the Azrael one mentioned or make some of their own. It makes the game much more interesting and enjoyable and Rocksteady did it masterfully.

Probably tim drake and dick Grayson robin

Honestly any robins or batgirls are unlikely since they said this is before their time, but it would be awesome. Deathstroke will probably be the only character we get besides batman but all of the assassins would be cool to play as

Joker, deathstroke, Dick, Jason and Harley.

1. A younger Dick Grayson
2. James Gordon
3. Alfred :D
4. Bane
5. Joker
6. Blackmask

And Jason Todd

I would pay good money to fight Killer Croc as him, throwing explosive dinner rolls in a duck tail tux.

Harley. Clayface too if possible. Would be fun to have different keys you hit to take on different forms and have your hands morph into different weapons.

Dick Grayson and Barbara Gordon

@akbogert: agreed, Babs' batgirl would be fun.

I'd love to play as Lt. James Gordon, even as a character for challenge mode.

@fatihbatman: This, I'd much rather have like 20 different Batman skins & no other character.

Let's just hope that Dick will be in it as Robin. If he is, it would be enough. If he isn't, I ain't buying the game. It would be great if robin had sort of his own story in the game, like team ups with the teen titans or young justice :]

@digbykong: That is exactly what I want. And I think we might actually get that. Kotaku had a guy leak them the title of the videogame before it was announced, he also talked about the invisible predator online mode before that was announced. When he talked about multiplayer stuff he said that in another game mode villains such as BlackMask, Deadshot, Deathstroke, Firefly, killer Croc and more would all be playable and perhaps customziable (probably in appearance). He said Firefly would be playable before Firefly was even hinted at. So fingers crossed.

Lady Shiva! I don't need her playable just there. And throw Catwoman off a roof, I hated playing as her.

@dagmar_merrill: Yeah, we could have missions like making good tea while not bitch-slapping Bruce when he gets on our nerves.

Also we must have The Creeper. One of my favorite comic characters, just to awesome to not be playable in the Arkham series/

hmmmmmm, could you be a Ditko fan? : 3

@avenging_x_bolt: How did you know that? haha :D

I hope Batman's in the game

Eh, we had enough of him in the last two games.
I'm thinking Dick Grayson would be a better choice.

Bronze Tiger would also be awesome

oh, just my natural detective skills

It'll never happen, but m3th wants Red Hood (Jason Todd.)

-m3th.O.D.-

While I doubt his inclusion I think Jason Todd could be very unique in the game and a great addition to the series.
