When Optimus Prime returned from Earth with the partially reformed Allspark, a team of the top Autobot scientists were gathered at Colony Omicron to study the massive fragment's properties. Two projects were approved: Project Matrix and Project Infinity. The latter sought to replicate the immortal pseduo-spark granted to Starscream by a sliver of the artifact.
The result was the abomination known as Protoform X; an unstoppable killing machine which slaughtered scientists and civilians alike before Depthcharge was able to force it into stasis lock. Primal was secretly ordered to find a desolate rock and dispose of X. When the Axalon
crashed on the primitive world where Blackarachnia was gathering her forces, however, the creature escaped. Now its mad laughter echoes through the jungles, as it attacks Autobot and technorganic alike. 
I know this is the one a lot of you have been waiting for. Rampage was always a character I liked better in theory than in practice. He had a great back-story, great dialogue, a great voice... but I couldn't stand his design. The giant, top-heavy kibble backpack, the scattered colour scheme? Blech.
With that in mind, I took the opportunity to redesign him for my
Beast Wars Animated series. I still wanted him to be big, and since his third, Transmetal 'vehicle mode' had been a tank of sorts, Shockwave seemed like a good place to start.
I decided to follow the cardinal rule of Transformers repaints: when in doubt, add more black. I replaced the lighter elements of his
Beast Wars colour scheme and darkened up his red and purple as well. The gold and magenta highlights really pop now, which is an added bonus.
I kept his signature three-barreled cannon, of course, and his cool horns and pedipalps. His head is kinda huge, but I think it does a good job of showing that this is Rampage, just not the Rampage you might be used to.
Speaking of his cannon, here's a better look at it. The barrels were originally pens. The left over parts make a pretty snazzy missile that screws right into the cannon!
Here are a couple of recreated scenes from the episodes 'Bad Spark' and 'Deep Metal', respectively. Like I said, great dialogue.
