Indeed, Marvel were the house of ideas back then. Some of the best Transformers fiction, to me, were the earlier comics by Simon Furman and Bud Budiansky. Some of it was pretty dark, especially the Generation 2 stuff, but the stories had more depth compared to the cartoons. It's a real treat knowing that it's those same people who wrote the original G1 bios.
Reminds me of a time in my childhood. Back when I was kid, my friends and I would sometimes go to another kid's house with a transformer each and play mock battles. There was this one time when I had Soundwave, and this other kid had his Blot attack my Soundwave, and I asked him "Why you attacking me? We're on the same side." To which he replied "You must die. You know our secrets. If you get caught by Optimus Prime over there, and you get interrogated; they'll know everything about us." Haha, priceless!
