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)
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)
