I preordered this back in Aug 2012 from Robot Kingdom purely so that I could get the Amazon Japan exclusive. At the time, the exclusive was being touted as an energon cube, where the regular version had no cube. But as it turned out, the regular release came with the energon cube, and the Amazon JP exclusive was simply an extra two cubes! Not really worth the extra price, considering a lot of regular releases were being shipped with a nice collectible coin featuring Soundwave's mug! I would've preferred that over 2 extra cubes.
But anyway, onto the figure!! Now with MP-13, where do you start? The main attraction being Soundwave, or the stealer of the show Laserbeak? :) I have to say, Laserbeak is an absolute engineering marvel!
That's not to say Soundwave himself is bad! He is of course an amazing figure! In doing this review, I realised I had not taken a picture of him in his classic boombox alt mode. You can see that in my video review that I'll post a link to below. It is every bit the G1 classic you remember!
Transformation wise, MP13 sits along side MP-8 Grimlock, MP-10 Optimus, and MP-12 Sideswipe as those Masterpiece figures with simple, elegant, and not overlay complicated transformations that are enjoyable to do! Others in the line such as MP-9 Rodimus and MP-11 Starscream have transformations that are either overly complicated, frustrating, or just so damn hard to do that you're always afraid something is going to break! Not with Soundwave.
Here are links to my youtube vid reviews of the MP-13 package. Hope you can check them out too!
