Throughout the original cartoon and early Marvel and later Dreamwave comics, Sunstreaker wasn’t really featured much. He was usually overshadowed by his more popular team mates like Iron Hide, Prowl & Jazz, hell, thanks to the live action movies, even his twin brother Sideswipe has gotten more exposure. It doesn’t help being the same color as arguably one of THE most iconic Transformers, Bumblebee. I guess there is only room for ONE yellow Autobot.
