Sadly, we are cheated a "Brawn of the Dead" pun-reference.
Although Transformers are often rebuilt or otherwise brought back from apparent death, there are also many examples of them being partially reanimated as zombies, either self-aware or under the control of another.
Generation One
- Impactor and Flame's army of zombies
- Optimus Prime
- Playback
- The bodies remote-controlled by Blackjack
Note: Metrotitan is not a reanimated Metroplex as is commonly believed.
Beast Era
- Galvatron
- Optimus Primal's original body
- Tarantulas
- The bodies inhabited by Megatron
Unicron Trilogy
- Dark Scorponok
- Starscream
