It’s the last Transformer in the Universe box and the other one that isn’t from the first Transformers Universe line. It’s not even from the line it was created for. I’ll get into it when I start reviewing actual Beast Machines toys but the short version is fans wanted a show-accurate Optimus Primal and the first two toys they released did not suffice. Air Attack Optimus Primal was the final depiction of Primal from that series and improved on the show accurate depiction. However it was not released in the Beast Machines line but the first Robots In Disguise line, and even then as a Toys R Us exclusive. I do now know why, but that’s how it happened. When my collection was smaller and I had more money I really wanted him, but it didn’t seem a good fit for the other RID figures, or even the Beast Machines figures because this sucker is rather huge. Not as huge as “supreme” Cheetor from Beast Machines (which I do not have and I don’t mind because I hear few good things about it) but a bit larger than he needed to be.
Also the toy has plenty of sound effects, including voice clips from Garry Chalk, the voice of Optimus Primal. This is rather unusual for toys, with the voices provided by cheaper voice actors. You’ll have to look up some video reviews to hear them all. I couldn’t find a video of just the voices and sounds, which is fine because I don’t have the batteries in to review that anyway. Instead this is just about the toy itself.
