It's not Shackwave. This is what Shackwave looks like (there are variants, but they all basically look like this). Also afaik Shackwave isn't a KO, but rather a legit release of the pre-Transformer "Astro Magnum" toy sold under licence through places like Radio Shack (hence the nickname), similar to how Microman and Diaclone were legitimately sold in Europe (Joustra Diaclone).
