Transformers Generations Legacy Series Leader Blitzwing
The other Decepticons don't care much for Blitzwing. Oh, they can respect that he's an absolute terror on the battlefield, using his triple-changing ability to maximum effect. Few things are more destructive and demoralizing to an enemy force than a tank landing on your front line at Mach 2. Blitzwing changes forms rapidly in battle to keep his opponents off-balance at all times. And through it all, he's laughing like a madman, because frag it, it's just funny to him.(credit tfwiki.net)
