Crumplezone
Wikipedia has an article about Crumplezone’s exploits in the animated series which reads:
“Crumplezone is a massive Transformer from Planet Velocitron (Speedia in Galaxy Force) who serves as the muscle to back up his partner Ransack. His bulky frame ( the biggest on Velocitron) possesses incredible speed, racing with fearsome swiftness along even the most winding roadways. He and Ransack were minding their business when they were forcibly drafted by Megatron.
“The two were quickly dispatched to locate Velocitron’s Cyber Planet Key. Eventually uncovering that it was the Planet Cup. The two entered the race, allying with Dirt Boss to win. Despite cheating their way through to the last race the two were beaten by Hot Shot and Override, forcing Megatron to personally intervene.
“Ransack and Crumplezone followed Megatron to the Planets Earth, Animatros and Gigantion in his quest for the Cyber Planet Keys. However this nearly proved their undoing when Starscream betrayed Megatron and sealed him, Ransack, Thundercracker and Mudflap in a steel globe. Crumplezone was the only Decepticon not trapped and managed to locate Scourge, who freed Megatron and the others.”
Surely, no machine on Earth today can stand up to Crumplezone in battle. I think he would just crush nerf bars with his fingers. For a more detailed account of Crumplezone’s fate in the animated series, you can visit Wikipedia’s article.
