Swindle is one of many Decepticons ordered to Earth by Megatron to cause havoc for the Autobot forces there. He's well suited to the task. Swindle is not a great fighter, and more, he's dumb as a post, but he takes great glee in blowing things (any "things") to pieces, and that's worth something, right? Generally he leaps and hops around the battlefield like a madman, blasting explosives out of his chest cannon and laughing uncontrollably. Havoc is a given when he's around. He's also an enthusiastic but unfortunately ineffectual interrogator. But don't get him started on Dead End, he hates him for some reason.

Sometimes there are lots of him.
On both sides.
