变形金刚：惩罚

When initially released, Punishment took place slightly farther into the future than the then-current IDW comic books were set. Over the following months, the comic books slowly introduced the new elements Punishment featured, then finally, The Transformers: Robots in Disguise #35 depicted Optimus Prime leaving Earth to return to Cybertron, leading directly into his role in Punishment. The series focuses on Optimus Prime's return to Cybertron following the events of Dark Cybertron, where he finds that someone is killing Decepticons. Now, Prime must track down and find the killer before it's too late.
