"Batman: Arkham Origins" achievement rewards have been leaked onto the Internet, revealing two previously unconfirmed characters in the franchise.

SPOILER ALERT: if you don't want to know who the two new characters will be, I suggest you scroll down to the leaked achievements list at the bottom.

The least surprising character involved in the series, but was not confirmed by the game-makers, is The Riddler. The achievements list reveals those pesky green question marks will return to the game.

The second character that will show up in 'Batman: Arkham Origins' is Black Mask assassin Lady Shiva. DC fans know Shiva as one of the most deadly assassins of the crew.

However, I am still keeping my fingers crossed for the "Batman" games franchise to feature Ra's al ghul and Talia al ghul in the origins stories, but I am excited to see Lady Shiva in the series.

For now, check out the following leaked list, and be sure to leave your thoughts in the comments section below.  The game will be released on Oct. 25.
