The second wave of Play Arts Kai’s Arkham Origins range has been revealed to be Joker and Robin.
As you can see, the Arkham Origins Robin is clearly different to the one listed for Batman: Arkham Knight shown earlier this year at SDCC. The Arkham Knight prototype for Batman was present at the same show (GamesCom?) as the Origins figures, but the Knight Robin was absent; perhaps they realised that they’d inadvertently leaked the character.
The only hints of a release date that I’ve seen for these are that it will be ‘soon’. The article will updated as I find out further details.
