I wish I hadn't sold off my Energon Shockblast...I kinda want to hunt one down again.
But agreed with the sentiment here, the TFP/BH Voyager Shockwave is a good lookin' bot. I wish it had a tiny bit more articulation in feet, but other than that it looks great. I myself traded up to the Takara Tomy Hunter Shockwave version (it's a darker metallic purple). The SDCC Shockwave's Lab version isn't bad either.
