I thought it was cool when Animated Shockwave turned purple in the TV show. I personally think that stuff like that should happen a lot more often in the comics and cartoons. But I suppose many people are still tired from this practice being commonplace from the RiD and AEC cartoons. The difference between occurances happening back then and Animated Shockwave was that the Japanese shows had the characters change color scheme to sell the toys. With Animated, it was more "hey, Hasbro's released a cool new repaint; let's work it into the show" - I never detected a hint of the purple Shockwave being shoehorned in with the sole purpose of selling the Shockwave repaint.
