Shogun

Not much is known about Sharp's life before the Weapon X Program. At some point of his life, Sharp served as a Delta soldier.

By unknown and unclear reasons, Major Sharp originally joined the revamped Weapon X Program voluntarily. Dr. Cornelius said he made him perfect, as he enhanced every system of his body, enough to get the upper-hand in a fight against Wolverine. But when he faced Wolverine, Logan tricked him into punching the glass where Cornelius was, so Logan knocked Sharp out, leaving him apparently dead.

After waking up in the destroyed Paradise facility with no memory of who was he or the voice in his head, Sharp and other Paradise subjects escaped after being attacked. Believing the voice in his head was that of Wolverine, Sharp sought out Sabretooth who only confirmed (after a fight) that the other person in his head wasn't Logan. After the other subjects were hunted down, Lord Ogun revealed himself, and tried to take control, but failed after Sharp realized Ogun was weak, but decided not to get rid of him as he needed his abilities to rescue the others. After successfully taking down many other subjects, Neuro informed him that they are all disposable, and had a genetic time bomb placed to kill them. The key to stop it was the regenerative healing factor of various previous mutant subjects, the "Wolverines", which they had to find.

After successfully finding and kidnapping the “Wolverines” (Mystique, Daken, Sabretooth, Lady Deathstrike, and X-23), and threatening them with the “control words” (that manipulate, sedate or even kill each of them), Shogun, Neuro, Endo, Skel, and Junk teamed-up with them to find the Adamantium-petrified body of Wolverine in the burnt-down Paradise facility, when they encountered and fought the Wrecking Crew, who had been hired by Mr. Sinister to search for the same.
