For starters... Of course Sanji's Raid Suit has invisibility abilities... What better ability would fit for son that Judge doesn't want to see at all?

Speaking of invisibility, suddenly ninja!

...Which in hindsight is not probably that surprising, since ninja are not exclusive to just one side of conflict. Still, Robin's situation is definitely worrying...

Finally, we have Big Mom's amnesia... that may or may not be temporary. Now this is where the fun will truly begin.
