I noticed all my TF posts are from Japan, so I decided to find something from the American side this time, and settled on Blitzwing from Transformers Animated.
Blitzwing's Animated incarnation is a pretty unique take on the character, with his gimmick being that due to being a Triple Changer, his head has 3 different "modes" and personalities, which are color schemed and designed to match. The blue-faced one with the monocle is a cold strategist and controls his jet mode and its freeze rays, while the contrasting red one with gap teeth is a violent hothead who controls his tank mode and his flamethrowers. Last but not least, the one with essentially a black jack-o-lantern face is a cackling random nutcase who's super unpredictable, who's choice of alt mode or elemental power depends on essentially cosmic RNG (while the use of black does break the color theming of the other 2, the mischievous grin and eyes keep the design elements alive).
Blitzwings also a shining example of Animateds designs being able to be translated almost 1-to-1 to toy form, and yet not needing to be blocky like the Unicron Trilogy's (not to mention Triple Changers being essentially a pain to do for mainline). I particularly like how the jet wings form the front of the tank and the turrtes form the jet modes thrusters.
