Is it me, or does the I-5YQ figure look like he has some sort of action/play feature in his chest? IIRC there isn't a storage compartment in his chest mentioned in Shadow Hunter, or the two Coruscant Nights books I've read, I think he's also in the med-star duology, but I haven't gotten to read those yet... Anyone able to confirm the trapdoor in the droid and if that's mentioned anywhere in the books?
A very eclectic mix of figures, but like Jayson said, the Darktrooper will ensure these are bought in sets of five, and I do mean sets.
