The first two episodes of Galaxy Force are edited together to create the first Cybertron episode, entitled "Fallen." This reduced the overall episode count to only 51, so to restore it to 52, the second Galaxy Force episode was again dubbed in full as "Inferno," a "lost episode" for the series, and the final episode broadcast.
For some unknown reason, the first two episodes of Transformers Cybertron - "Fallen" and "Haven" - were not shown when the series premiered on Toonami. In other countries such as Canada and the UK, only "Fallen" was skipped, but both eventually aired in America when the series debuted on Kids WB. YTV aired Fallen in 3 Hairy Thumbs Up and subsequent reruns.

This is the first series to feature Primus as a physical being.
Transformers: Energon featured Primus as an energy being hidden deep within Cybertron, but never depicted him as having an actual body. His design is based on a hypothetical robot mode for Primus/Cybertron, which was in conjunction with the Dreamwave Productions Transformers: The War Within comic book mini-series. Cybertron is the first TV series since the 1980s to feature Soundwave, a new incarnation of the popular G1 character. The original Soundwave even received a sneaky cameo in the series, when a stereo cassette deck based on his alternate mode was used as a prop in two episodes.
Ironically, Galvatron was the only Decepticon in this series who ended up dead, despite being generally considered by fans to be the most powerful villain/antagonist in Transformers: Cybertron. This is the only instance in a Transformers series where only the most formidable villain dies first, leaving his fellow Decepticons alive. As for protagonists, Vector Prime was the only Autobot who died. This is in contrast to Transformers: Armada and Transformers: Energon, where numerous characters were killed off by the end of the series.
The Cybertron incarnations of Starscream and Brakedown are based on the redesigned versions of the original Starscream and Kup created for Dreamwave's War Within series. In the episode "Balance," when Primus is recounting his tale, a brief scene shows four Transformers around a layout of the space bridges. Identified only as "wise elders," the four robots are, in fact, the original Optimus Prime, Ultra Magnus, Rodimus Prime and Jazz.
A large number of famous quotes from past Transformers series (most notably The Transformers: The Movie) appear throughout Transformers: Cybertron, from "Till All Are One," to "Such heroic nonsense!" (note: The latter quote also (re)appeared near the very end, with a twist. With the wording changed to 'such villainous nonsense'.)
In "Search" when Megatron talks to Scourge in the Jungle planet's throne room, there are three carvings on the wall -- a mammoth, a gorilla, and a lion. This is a tribute to the three Maximal leaders of the Beast Wars era -- Big Convoy, Optimus Primal, and Leo Prime (aka Lioconvoy).
In the final episode, during the racing scene on speed planet, Override can be seen dropping her rear wheel into the gutter on the road to pass her opponents on the inside ala Initial D.
In the episode "Sand", Sideways utters the line "Whoever loses, I win!" in possible reference to Alien vs. Predator.
In the episode "End", Optimus Prime says "Come Together, right now, over me!" as he joins with the other Tranformers to defeat Megatron. This is a quote from the Beatles song, Come Together
