A transformer cannot simply be made. Only Hasbro's magic and Dark Energon can revive them. So you made his body, but haven't brought him back. Nice job. Course, this will piss Unicron off enough to destory Lilith (seeing as he said to kill Optimus and now he is now not destroyed)

What he summoned wasn't Optimus's body, it was his soul. Which had been fused with the Matrix, if I recall. Then, he put together a body for him.
