I know it technically is more Diaclone than Transformers, but Sideswipe actually has his G1 colors and not his Diaclone colors. And the Transformers line eventually took over and substituted Diaclone. I think it could be more useful for Danbooru users to have both Diaclone and Transformers tags so anybody who finds the image while searching for Transformers learns about the history of Diaclone and the origins of Transformers.
