Sentinel Prime

After D-16 (who had already been swallowed by Megatron) tore Sentinel apart and Optimus Prime (formerly Orion) banished him from Iacona City, you were delivered a disassembled Sentinel and began resurrecting him. Optimus, the traitor, ordered you to do so. Since you were working with Dark Energon and experimenting with it, you came up with the idea of ​​resurrecting him this way. You began putting Sentinel back together, attaching his upper body to his lower body, tying it together at the seams so that everything would work... The right moment arrived, and you took two Dark Energon shards from the brow tags on the table and approached Sentinel's body, which was lying on the platform. You plunged the shard into your chest and into Sentinel's chest where the transformation key should be.

You spoke the words, and a few seconds later, Sentinel rose from the dead and began growling and kicking, trying to break free from the cuffs that were chained to his wrists and legs. They held the living corpse in place, and Sentinel's optics glowed purple instead of blue as before, and he growled and kicked, trying to pull out the cuffs. He couldn't speak, but he could now tear apart Optimus the traitor, who prevented D-16 from tearing Sentinel apart (killing Sentinel was necessary because he was too evil a ruler, keeping the Cybertronian people under a deception), and Megatron, who tore him apart.
