the G1 cartoon episode "Five Faces Of Darkness" implied a connection between Blitzwing and the Quintessons that was never expanded upon. (1986) Animated would coincidentally give Blitzwing the same face-swapping shtick as the G1 Quintessons. (2008)
despite being used only once in the G1 cartoon, G1 Optimus and Megatron's energy axe and mace accessories are very popular pack-in weapons, especially in Japanese figures. This can be attributed to how that scene was prominently featured in the JPN opening for the cartoon.

MP-36+ Megatron has Decepticon symbols on his ass. (2018)

In early episodes of Beast Wars, Scorponok's missiles had Maximal symbols on them, the equivalent to carving an enemy's name on your bullets. Many viewers failed to pick up on this though, and they were promptly replaced with Predacon faction symbols to avoid confusion. (1996)
the regular Voyager-sized figure of Cybertron Starscream was never released by Hasbro, due to them wanting to push the larger Supreme-sized Starscream instead. (2005)

the 2019 IDW TF comic ends with the Autobots all leaving Cybertron to fight another day, which leaves Megatron in control (albeit it being a pyrrhic victory for him). This effectively makes this one of the few TF continuities that ends with the Decepticons winning. (2022)
IDW's Beast Wars comic ended on an extremely rushed and abrupt note due to their loss of the Transformers license. The editors' note at the end of the final issue goes into detail on the many, many aborted plot threads the writers wanted to follow up on. (2022)

Animated Blurr's crushed cube form was supposed to show his spark being visible, to show to the audience that he was still alive. This detail didn't make it into the show, leaving Blurr's fate ambiguous. (2008) (Blurr eventually came back in the BotCon 2015 script reading)
