Mercury (COP)

Mercury is a Mutacon from the Aligned continuity family.

The Mutacon leader Mercury always wears her emotions on her face, a face that's in a constant state of subtle, transforming flux. Mercury herself is equally as mercurial: free-spirited, upbeat, energetic, flirty, and hyper-outgoing. She is easily bored or dejected, but just as easily bounces back into giggling good spirits, amused by the silliness of the entire universe.

When she sees something interesting she can't help but use her super-transformation powers to copy it.

Mercury thinks Decepticons in general and Megatron's concept of "peace through tyranny" in particular are roll on the floor, laugh out loud stupid.

Fiction

Covenant of Primus

Like all Mutacons, Mercury fled the destruction of the Neutronia colony when the Rust Plague hit. In space her starship crew found the Transformation Cog of Amalgamous Prime near a black hole. The mystical object granted them infinite transformation and infinite combination abilities. However they soon found they were beginning to involuntarily merge into one being, slowly losing their own personalities and memories.

Optimus Prime and the Ark crew met Mercury's crew of pirate Mutacons in space.

Mercury communicated with them and offered to trade energon stores in return for help in locating Amalgamous Prime or for the chance to merge with Optimus Prime to learn how to change into his form. (Bulkhead thought that sounded "kinky"). She caused a moderate uproar of whistles and cat-calls among the male Autobots when she visited Prime in person. The Matrix downloaded a history of Cybertron since the Rust Plague to her and she fell on the floor laughing at how dumb the Decepticons were.

Prime promised to help the Mutacons solve their shape-changing problem after the Decepticons were no longer a threat. That was good enough for Mercury and she happily returned to the others and set about delaying the pursuers so the Ark could escape on their way. Transformers: The Covenant of Primus
