After Beast Machines ended, Hasbro planned a follow-up series called Transtech. The series was supposed to bring back some of the characters who died in Beast Wars along with some characters from the original 1980s cartoon, all in new, organic-looking bodies, with vehicle alternate modes instead of the animals used in Beast Machines. Many concept sketches and even a few toy prototypes were made, but Hasbro scrapped the idea, bringing Car Robots to American markets as a placeholder until Transformers Armada.
Concept sketches or prototype toys have been seen for Blackarachnia, Cheetor, Depth Charge, Megatron, Nightscream, Optimus Prime, Scavenger, Shockwave, Soundwave, Starscream and a new character called Immorticon. There were also rumors of a Transtech Dinobot.
It is generally believed that the concept for Transtech Cheetor inspired the design of Transformers: Cybertron Brakedown and the concept for Transtech Megatron inspired Armada Megatron.
