I haven't been this confused about continuity since I was trying to figure out how RID fit with G1 before I realized that it doesn't. There's no doubt that RID2 is a sequel to Prime. It directly follows events that happened in that series. There's a few minor continuity errors though. Bumblebee actually addresses the fact that Starscream's design has changed and they show his Prime design in a flash back. Soundwave makes an appearance in the show looking exactly like he did in Prime. However no one makes any mention of the fact that Optimus and Bumblebee have upgraded bodies. In fact in one episode they show a video of Bumblebee from the past where he should like he does in Prime but for some reason looks like his current form. Rescue Bots on the other hand I never believed was connected because Optimus and Bumblebee again have completely different designs and with it supposedly taking place at the same time it really makes no sense. This is especially true with Optimus who in Prime/RID has had three different bodies none of which look anything like his RB design while in RB he's maintained the same form threw all four seasons. Prime season 3 and Robots in Disguise never make any mention of Optimus being able to transform into a T-Rex which in Rescue Bots by this time he has that capability. So how are Optimus and Bumblebee changing bodies, especially considering there are several times when Optimus would be switching to a flat front truck just to answer a phone call and then have to switch back to a long nose. What is even the point of that? Sideswipe and the little Cyclone Mini-con on the other hand did appear on Rescue Bots looking exactly like they do in RID. During Prime RB never made any direct references to anything in Prime. Optimus says something about his medic but never names who that is. I'm not sure how we went from no references to any other show to having guest stars from characters in another show. With that being said, even though they've made it perfectly clear that Rescue Bots season 4 and RID are happening at the same time there are still a few problems other than Optimus and Bumblebee looking different. 1. If each season of RB directly corresponds with a season of the main show that would mean that season 4 happens during a time when Optimus Prime is dead yet he's still very much alive. 2. Bumblebee has his own space ship on RB which is weird because that ship is never seen on RID. 3. Sideswipe in RB is freaked out by humans which is weird because he was never like that on RID and even if he was he should be use to them by now. 4. The first time they run into Cyclone Mini-cons is in a later season which should take place after RB so the timing doesn't really match up. In short these shows fit together about as well as the Unicron Trilogy. Which is weird. The UT doesn't quite fit because of terrible dubbing and the fact that Hasbro tried to cram in a series that was never intended to fit into the same continuity. This shows were planned to fit together from the start and yet they still don't work. I think the issue here is that Hasbro handed everyone a continuity bible but instead of enforcing that as a strict, this is how everything should connect, it's more of a suggestion than a rule. The different teams have far too much freedom to do their own thing and so we end up with things that share similar stories but aren't exactly the same story. It's kind of like making a puzzle. If you start with the picture first and then cut the pieces you'll get a puzzle that actually fits together perfectly but instead Hasbro decided to cut the pieces then give each piece to a different person to paint on the different sections of the picture. As a result when you put the pieces together you get what is generally all one picture but the lines are all skewed a little and don't exactly fit quite right. I suppose it's better than taking a piece from an entirely different puzzle and trying to force it in there but it's still not good. My personal head canon is that RB is it's own universe. Some similar events to Prime/RID have happened with some differences. This would explain why Optimus is a flat nose, never upgrades, and why the Prime/RID version isn't a T-Rex. The events that lead to Optimus' upgrade to his Beast Hunters body never happened or happened differently in the RB universe, his death at the end of Prime never happened in the RB universe. Optimus never became a Dinobot in the Prime/RID universe. I think in the RB universe Bumblebee, Sideswipe, and Strongarm originally came to Earth on board Bumblebee's ship rather than the space bridge like they did on RID. I also think in the RB universe Sideswipe has never met a human before Griffin Rock. They are still based in the same scrap yard but for whatever reason the scrapyard in the RB universe does not have Denny and Russell Clay. Maybe they never existed, maybe they sold the place before they would of met the Autobots, maybe they do exist but never lived there. Whatever the reason is, I think the Bee Team in RB is based in an abandoned scrap yard rather than a working one which would explain why Sideswipe acts like he's never seen humans before. That plus they met the cyclones a little earlier than they did on RID. That's how I'm working it out in my head cannon anyway, they're similar universes but not exactly the same because that's the only way I can explain away the continuity errors without getting a headache. I think I'm just going to put Prime and RID into separate but similar universes as well. Oh another problem is the timing. It's never really said exactly how far in the future RID is from Prime. RB season 4 however we know is exactly three years after season 3. So considering how active Cybertron is at the start of RID compared to how dead it was at the end of Prime it's hard to believe that much has changed in only three years. The RB are told that Cybertron is uninhabitable at the start of the series but they are never informed about it being revived which makes me think that never happened in the RB universe. And considering how they've managed to rebuild Cybertron so quickly I also think more than three years passed between Prime and RID. Either that or it was revived much earlier again leading to a continuity error that doesn't quite line up with Prime.
