Today I went into Walgreens and came across the same Red Hood figure. I took advantage and took pictures of the art and the back unlike the last Red Hood articles.
Here is a new and not seen before artwork for Red Hood aka Jason Todd!
This image below shows the info provided by the game for the players. It appears on the info that the Red Hood's identity is unknown in the Arkhamverse. The only time we've heard of Jason Todd in the Arkhamverse was in Arkham City in a challenge map, where the Joker makes a joke on him killing a Robin. Could it be that Red Hood will not just make his first appearance in Arkham Knight but his introduction to Batman and the others as well?
