Hooligan

If Skywarp needed competition in the cruel practical joker department, he's found it in Hooligan. Only marginally smarter than fellow Cyberjet Space Case, his idea of a great joke is usually something mean spirited and destructive. Hooligan doesn't care who his target is, either: Autobot, human, or fellow Decepticon. His greatest flaw is a tendency to go too far in pursuit of a good joke: most robots would know better than to pull a prank on Megatron, Hooligan... not so much. Given that, it's a wonder he's still functional. But hey, some people do worse, and they get to live.
