James Howlett (Daken) (Earth-52161)

Idea Phase
Weapon X, a sub-division of HYDRA, was given the order to create a clone of the mutant Wolverine. The first idea was to create an exact copy, which would have been Daken. However, at the last minute, the order was changed to create a feral clone instead, so Daken's creation was put on hold, maybe permanently.

Reactivation
Almost a year later, someone had snuck into the locked lab that held Daken's inactive body. When his eyes opened, Wolverine's memories went pouring into his mind, as well as his own, including his creation and deactivation. He murdered the man who set him free and quickly escaped from the Weapon X facility.

Search for Wolverine
Not long after he escaped, Weapon X discovered it and picked up on his vital signs. He began using his senses to track Wolverine to America, Westchester to be specific. He used the implanted fighting and stealth skills he was given to sneak into the X-Mansion and silently take out the X-Men one by one. When Wolverine found out, the two of them battled and Daken proved that they were on the exact same level. They each soon realized they would not be able to defeat the other, but the X-Men began recovering and Jean Grey managed to defeat Daken with a psychic blast, and he was taken to the Vault.
