Here's my idea for the Renegades, the Renegades are made of a few GoBots as well as different Transformers from across the universe. In this idea Cy-Kill brainwashes Aileron into joining the Renegades and her name is changed to Crasher. Maybe some Eukarians are the IDW version of the Monster GoBots.

Also the Last Engineer was a Spaceknight and used the Spaceknight tech as well as Cybertronian tech to make the GoBot bodies.
