It appears that both Nico Robin and Batman have been captured by Santa! As it turns out, the Straw Hat Pirates have been stealing a lot of loot lately...so Santa captured Nico Robin...unless they give up all the loot they stole Santa will make Nico Robin listen to repetitive Christmas songs! The horror!
As for Batman...well, he beat him up and sent him to Arkham Asylum for polluting Gotham City with his coal mine...how are people supposed to breathe while THAT's still up and running? Fortunately, Batman shut it down.
But it looks like Santa's going to get the last laugh! He hit Batman on the head with a shovel and kidnapped him too! Either Gotham City releases each and every criminal in Arkham Asylum...or Santa will force-feed Batman Christmas Cookies until he becomes Fatman! What a horrible situation!
Strangely enough Nico Robin seems to be enjoying herself...why you may ask? Because she thinks Batman (and of course Bruce Wayne) is hot.
