Goofs: Megatron's Decepticon logo is briefly missing when he exits the spacebridge on Cybertron.
Bumblebee is seen in robot mode with Optimus Prime and other Autobots when Sparkplug begins to worry about him and Spike not having returned from spying on the Decepticons just before Bumblebee returns in car mode.
In the 1986 comic #18 "The Bridge To Nowhere" the Spacebridge is in fact a partially constructed road bridge, much like the Golden Gate Bridge. Half way along the bridge is the Spacebridge portal.
There seems to be two Starscreams standing next to each other after Megatron disappears into the space bridge but, in the next scene it is Skywarp who is standing next to Starscream.
Optimus, Ironhide, Ratchet, Prowl, Bumblebee, Cliffjumper, Jazz and Gears are trapped in the cave by the decepticons because they filled the escape route with stones and boulders. How did Brawn, Sideswipe, Sunstreaker and Trailbreaker get in the cave?
How come nothing seems to have happened on Cybertron? It was low on energy when Prime's and Megatron's forces left, yet four million years later it's in the same state. And how does Shockwave know that now is the right time to contact Megatron?
Bumblebee: (Upon discovering that the cave doesn't contain the space bridge.) I don't understand it.
Gears: I think your memory chips could use a few volts to shake them up.
Soundwave: Ravage, stand aside.
Spike: (Energon cage disappears.) Well, uh, I guess I've served my time and I'm free to go, huh?
Soundwave: Free to go.. to Cybertron.
Optimus Prime: (shocked) Megatron lives.
Bumblebee: How are we gonna get out of this?
Spike: By the skin of our teeth!
Bumblebee: I didn't know human teeth had skin!
This is the first time Teletran-1 is referred to by name, although Optimus Prime refers to it as just Teletran in this episode.
In this episode, Optimus Prime´s precision shooting can be seen when he opens the Space bridge transport ship with only one shot, destroying the belts that restrain Spike.
Optimus Prime's head is altered from this episode onwards. Instead of a rounded head with a slim metal mouth plate, Optimus has a square head with a fuller, more mature mouth plate.
