Zombie

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

• Flame's army of zombies, which included the undead Impactor
• Optimus Prime
• Starscream
• Playback
• The bodies remote-controlled by Blackjack
• Black Zarak and possibly the rest of the Nine Great Demon Generals

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
• Dark Crumplezone
