Shockwave is a massive triple-changing cycloptic Decepticon. Apparently, he's been working to oust Megatron since before Starscream got the idea. Starscream decided Shockwave will be lucky to be kept as a pet if he takes over.
Shockwave is described as a hyper lethal Decepticon assassin. He is also a scientist, coming up with twisted and soulless experimental Decepticons. His weapons are as powerful as that of a small army, his fusion cannon is powered by his own personal reactor mounted on his back. Shockwave has control over the massive, vicious beast known as the Driller and rides it into battle. He & Nicole do make up when Unicron merges Nicole & Anais into Scourge. He is to appear as one of the main villains of the Adventure Time Crossover 3 in his G1 variant , which he can turn into a hand blaster.
