Here's my explination for corpse armour prime: Defender Optimus prime was winning the battle against Mindwipe, but then Mindwipe bought back the body of Jetfire back to life and hypnotised him, he pits Jetfire against Defender Prime. Jetfire is losing so he tries to transform. Prime brings out his hooks, screaming "I've tried the face, so give me your LEGS" and rips the off. Jetfire dies. Mindwipe comes back with a new army, prime slaps the legs onto his Back and screams, "Give me your Face!" he rips through the army, most of whom are Autobots, without a second thought, he rips apart Mindwipe into peices even though he baegs for mercy. He screams "Come get me, face me, I AM BERSERKER PRIME, i show no mercy to autobot and decepticon alike. I need more faces for my collection!"
