Warner has finally released a trailer showcasing the Penguin, as well as releasing artwork for assassin Talia al Ghul, confirming the daughter of Rha's al Ghul will be appearing in the sequel.
Penguin was only referred to in Arkahm Asylum, with a trophy case in one of the halls containing his trademark umbrella. The bird-like mob boss is getting a bigger role this time round - check out the trailer.
Whereas Talia al Ghul's presence is more a mystery. The daughter of Rha's al Ghul, the assassin who was portrayed by Liam Nesson in Christopher Nolan's Batman Begins, has appeared in numerous Batman comics over the years. She has a dynamic to Batman that's similar to Catwoman; criminal but who was romantically entwined with the Dark Knight.
In the comics, that union led to the reveal in recent years that they'd conceived a son, Damien Wayne, who was also trained as an assassin and now has taken over the mantle of Robin.
