A greasy, amoral smooth-talking weasel, Thunderclash has somehow managed to lie, cheat and swindle his way into a positon where many larger and more powerful Decepticons actually owe him... or at least fear that he may blackmail them, so they do what he wants. Utterly self-interested, Thunderclash doesn't do anything unless he can see a way to personally profit from it. Some say he started the rumors that his occasional partner Skywarp is only in the position he is thanks to a healthy dose of nepotism. Needless to say, Skywarp hates Thunderclash's guts, but can't do a whole lot about it... yet.
