Technically speaking, the only figure among the 12 that was involved in Order 66 is the Anakin because he led the march on the Temple.
The other 11 figures either had nothing to do with Order 66, were dead when it happened, weren't incarnated when it happened, or are the wrong paint scheme or EU altogether. Eh, I guess Obi Wan counts as a 2nd figure out of the 12 that was involved, he may have received the first shot fired as a result of Order 66.
Hard to believe Hasbro created something as cool as the Neyo 2 pack among what is largely a pile of crap comprising this Order 66 sub-line.
