While this is a huge surprise for fans like me, this dragon reminds me of some of the decepticons that were long forgotten in the media over the years, and based on the possiblity of this dragon Optimus Prime will be fighting in the next year's film is a multiheaded dragon, possibly a hydra, it is possible that this mechanical menace will be classified as a Terrorcon
Clearly as you can see from the picture above the multi headed dragon that Optimus will slay with his sword could be one of the two terrorcons on the right, Sinnertwin or Hun-Grrr or possibly the Terrorcons' combined form, Abominus or the Transformers Cinematic version of Trypticon
Otherwise this menacing creature will end up being an original character as people making comic book movies usually do these days, especially cartoon animators.
And because of the artwork on this banner, Transformers The Last Knight is sure to be the next film inspired by the stories of Knights fighting Dragons
