Another one of those designs that popped up from nowhere.
He was an invaluable spy for the Decepticons and worked many missions with Soundwave, their skillsets combined made them a formiddable information-drain.
Reflector was unable to spend a lot of time on Earth, however, he accompanied Megatron to one of his meetings with Gyconi, recording some information Megatron would’ve rather kept to himself and the Crime Lord. As such he decided that he didn’t want to waste time with all that annoying fiddling about with memory circuits, and thought it easier to just end Reflectors service.
By ripping out his heads one-by-one and leaving the body in a ditch, to quickly run out of Energon and it’s life-support systems to shut down.
(I love this design though tbh)
