Reportedly, most of the voice actors didn't like working on the show due to how their characters had been rewritten compared to the previous series. Scott McNeil (voice of Rattrap, Silverbolt and Waspinator), who was one of the few returning voice actors not to hate the series, at times mentioned how his colleagues, for instance Garry Chalk (Optimus Primal) would flip out in anger between recording sessions.
Famed Transformers fiction writer Simon Furman considered the series to be too dark for children. Note that Furman is no stranger to darker themes, as his comics were full of horrific stories, violence, gore and death, although they were aimed at a slightly older audience than this show.
For a long time, this was the only western-produced Transformers cartoon series not to feature any human characters, apart from a brief flashback that shows prehistoric hominids. Further series with no humans would only be made in the mid-2010s.
Was originally meant to be followed by a sequel in 2001 called Transtech. It would have also taken place on Cybertron and would have seen the return of several famous, classic Transformers characters, such as Optimus Prime, Starscream, Shockwave and even Depth Charge. However this series was something of a failure for the Hasbro company. Following on the success of the Beast Wars: Transformers (1996) line which had managed to revitalize the Transformers brand, this series in turn made consumers turn away from it. Hasbro therefore canceled their development of Transtech, even though several toys had already reached their prototype stage, and began working together with Takara, the Japanese owners of the franchise, on creating an entirely new series in which the characters transformed into vehicles again instead of animals. This became Transufômâ: Maikuron densetsu (2002), which was badly received by fans but was a giant success with kids.
The only Western Transformers cartoon to feature characters giving the middle finger. Thrust does so to the Maximals in two episodes.
