Has there been a list of heroes and villains you can have in it?

I am very impressed by all those iterations of Flash so seems like even obscure characters be in it.

I've been reading the NeoGAF thread where one of the game's artists (named SpacePirate Ridley) is answering different user's questions on whether certain DC characters are in the game or not.

Check it out.

Speaking to Polygon, Scribblenauts Unmasked's senior producer, Caleb Arseneaux said the game contains every character who has ever appeared in a DC comic book, from the Justice League, to all the variations of Batman and Superman, to the most obscure characters who have only had brief cameos in the comics. He said that Scribblenauts is all about letting players have "whatever they want," and the DC universe is so rich with characters who have so many superpowers and abilities, that blending the two franchises made sense to the development team.

Holy Scribblenauts Batman!  That is insane!  I will buy this now. Seriously, the animator is throwing everything, the kitchen sink and all variations of the kitchen sink at this!

Note: They deleted all the artists posts and member responses in that thread. Seems he divulged a bit too much information.

Essentially he stated an absolute ton of characters will be in it with only the most obscure not making the cut (and I mean really obscure here!)

Yeah, I just saw that as well. Definitely not good... I hope that the removed posts is punishment enough.

Please Warner Bros., don't hurt SpacePirate Ridley! D:
