The Transformers #162

The Decepticons create their new Pretenders that look like flesh & blood monsters rather than Transformers, but the Autobots manage to steal and copy their technology and create their own team of Pretenders that look like humans. The Autobots discover that a copy of Optimus Prime's mind had been stored into a computer game after his death, and Optimus Prime leads his new Pretenders to victory over the Decepticon Pretenders, believing it is just another computer game.
