I have no idea who Sideways even is. XD In short, no. Chances are, if any bots didn't appear in the show or the AllSpark Almanacs, they won't appear or be brief cameos as best. Few exceptions of course such as the news bots from "Around Cybertron" and Nancy.
All I know about Morphobots were that they were plants shown in the G1 cartoon. I was just doing research in the TF wiki to find an alien plant that occurred in the TF franchise than make up my own (which is my preferred method - I only make up stuff if I really have to).
