Interestingly, Zero implements a "kamikaze" (suicide) plan. His alt mode is a Mitsubishi A6M Zero plane which was used for kamikaze missions.
Despite his loss, Zero has shown that he may very well be a more formidable enemy than Cy-Kill.
The only rogue Renegade not referred to by name is "Tux" (his toy name, in the series he's called 'Stretch.") He is the Gobot that transforms into a Rolls Royce Phantom VI limousine.
The episode teases that Zero may be a returning villain.
This story shares plot similarities to The Transformers animated show episode Starscream 's Brigade. Where Starscream would put together his own Decepticon force ; The Combatacons , in order to depose Megatron.
