- Clio is a Decepticon from the Generation 1 series.
Clio, according to reports, is a Decepticon Powermaster who transforms into a car. Her Powermaster partner is called Patra.
Unless, of course, she doesn't actually exist. The only mention of Clio and Patra comes from Blaster's letters column from the UK comic book telling the "true" tale of the Transformers, replying to a letter from a human comic-reader who had seen a commercial for the "Clio" car that had the vehicle transform into a robot, and suggested the Autobots recruit it. Blaster said they'd been beaten to that punch.
Blaster could very well be making it all up as a joke. The Transformers who have answered human mail tend to be jokesters or flat-out insulting towads their readership.
