What if Smokescreen was originally a container created by Master Titanium to store the source of fire, and then inexplicably gained its own consciousness?
Master Titanium's explanation to Optimus Prime is that he sent the fire source to other galaxies.
Smokescreen didn't know he was the source of the fire, and Master Titanium later trained Smokescreen as the next leader.
Before the Decepticons are about to attack the Iron Castle, this information is hidden in the energy treasure, and it is set to automatically unlock when exposed to the smoke screen.
Just, this kind of thinking is quite fun.
