Most likely the final release of this amazing genre re-defining mold of Movieverse Optimus Prime.
This version is painted to match Revenge of the Fallen's darker color scheme and includes the Grinder hooks and two sword accessories. Also notice that this is the mold that pre-dates the Dark of the Moon abs.
This guy can combine with ROTF Leader Jetfire as well and is meant to pair with MB-16 Jetfire.
Mint in sealed box!
