Shockwave was sitting on a shelf at Wally World, and despite all of my wife's bitching, she actually picked it up and said "is this one that you're missing?" Needless to say, it was instantly in our cart and is now a part of my collection. I think the only ones I have missing are Swindle and Ravage, unless there are more than 12 Alts that are out now.
This may have been mentioned before in the old thread, but the box reads SHOCKBLAST and the license plate reads SHKWAV. Also, the instructions show Jazz rather than Shockwave. I thought it was kinda cool that they made his head to where the light from the room makes it look like his eye lights up. Neat trick if you ask me.
