Universe Deluxe Wave 2: Acid Storm is a green repaint of the Classics Starscream mold, intended to resemble the green jet of the three Rainmakers that served in the command of Shockwave on Cybertron. Acid StormÃ's wings are equipped with underslung projectile-firing cannons; in robot mode, the oversize cannons serve as Acid Storm's guns, and must be converted to hand held weapons in order to allow Acid Storm's full range of shoulder articulation. In the original cartoon episode, "Divide and Conquer" Bumblebee, Ironhide, Bluestreak and Trailbreaker were accompanied by Chip Chase on a threadbare mission to Cybertron to retrieve a cosmotron needed to repair the heavily damaged Optimus Prime. The Rainmakers, a trio of Cybertronian Seekers dispatched by Shockwave, generated an acid rainfall that temporarily discombobulated the Autobots.
