John Shepard (OU)

John Shepard was a human man, widely recognized as one of the most dangerous in existence. During his life he organized nearly as many deaths as Naju, with whom he was later allied, and was directly responsible for multiple wars and conflicts across the multiverse. He was the leader of the organization Zion, and later a member of the Brotherhood of Steel.

He was eventually killed by Blackout, though this wasn't the end of his existence; his consciousness somehow continued to exist until it was salvaged into an antidermis vessel by the Shinsengumi. This is the form in which he currently exists, restrained aboard the Takemikazuchi vessel Covenant in a hardened protodermis web - all on the orders of the Emperor of the Takemikazuchi, Sefer Yetzirah.

Biography
In his life Shepard was truly malicious. He had no concern for morality, and would betray or use anyone he saw necessary to achieve his goals. Despite being a human in a multiverse ruled by super-powerful beings such as Makuta, Shepard was able to keep pace with his enemies by commanding huge armies, masterminding grand schemes and constructing immense superweapons such as Side 8. As such, he was not overly impaired when his physical body degraded, in his later life, to the point that he was reliant on a wheelchair.

Little is known about his current state, though during his salvaging Lucrezia Sephirah remarked that his psyche was still intact. He demonstrated immense rage, attempting to morph his antidermis form into a humanoid shape to attack, but was prevented from doing this by being frozen in protodermis. Since then, he has remained inert.

Relationships
Blackout was one of Shepard's enemies throughout his life, as well as being the one directly responsible for his death. Short of having lost his memory, very little is going to be able to prevent Shepard from fully hating one of his primary enemies. It is unknown if Shepard is even aware of Sefer's existence, though it is clear that Sefer is aware of his, as she ordered his salvaging.

Trivia

 * Shepard is named after, and originally resembled, the Stargate Atlantis character John Sheppard. However, his last name is spelt differently - purely because User:FullFrontal didn't realize at the time that the Stargate character's name was spelt with two 'P's. The misspelling has since been retained, for continuity.
 * Curiously enough, Shepard's misspelt name is the same as that of the protagonist of the Mass Effect series.
