Secret Files and Origins: 
The ''very best at what he does'' as he calls himself, Wolverine is one of the world's oldest mutant and one of the first publically recorded as well as a member of the premier mutant team, the X-Men.

Born sometime between 1882 and 1885 as the illegimate son between Elizabeth Howlett and the Howletts' grounds-keeper, Thomas Logan, James' mutant power awakened after a confusing incident concerning his actual father and whom he believed was his father, ending on the death of both. After said incident, James alongside a friend of his family, Rose O'Hara, leaving the Howlett' State to his mother, his un-born brother and his half brother ''Dog'' Logan

For the next couple of years, James (now under the name Logan), and Rose lived near South Canada, up until Rose was accidentally killed by Logan after trying to break up a fight between him and his half-brother, Dog. After so, Logan would drift from city to city, in the in between time participating on the first World War. By the year 1945, Logan encountered himself on Japan held in a POW Camp near Nagasaki. During the atomic bombing on Nagasaki, Logan was left free, in the insuing time saving a young Ichirō Yashida.

After the end of the war, Logan returned to Canada, joining Department K (a covert special branch of the Canadian Goverment) as an operative. During that time, Logan became a part of Team X, alonside Victor Creed, Larry Trainor, David North, Slade Wilson, Donna Diego and Kayla Silverfox, a team of mutant mercenaries. 
As a part of this black ops team, Logan would be experimented on alongside some of his co-members as a part of the Weapon X program in order to augment their mutant abilitties. Logan's bones were infused with a indestructible metal known as Adamantium, making him completely impenetrable. Alongside with a now metallic skeleton, Logan's memories were erased as per for him to be brainwashed into becoming the perfect killing machine. However, while the doctors were able to erase his memories, they weren't able to control the now-feral Logan, whom escaped shortly after.

For the next 30 years, Logan's memories began to come back, however, his memories of killing Rose or ever being a soldier were completely erased. In the ensuing time, Logan got acquainted with a man known as Charles Xavier after he tried to recruit him as a part of his team of Mutants. While originally Logan refused, after learning Charles had the abilitty of unlocking his lost memories, Logan approached him in order for him to help him. While Charles was able to have him remember how he ended up this way, he wasn't able to have him remember anything else.

After so, Logan became an ally of Xavier, helping him to find mutants in need of help whom would need of his assistance arround the country side. However, by the year 1995 after Xavier's X-Men were lost on the island known as Krakoa, Logan returned to the mansion as per Charles' orders as to form a new team in order to find the Original One. Logan alongside Cyclops (whom was able to return and inform Charles of the situation), Storm, Ray, Citizen Steel, Metamorpho, Black Lightning and Monocrome became a part of the New X-Men team.

Years later, the Wolverine would be a part of the many heroes whom saved Earth from the insuing White Martian Invasion alongside the X-Men and recently formed Justice League

Notes:
Alright so Logan's Wolverine Costume was based mostly upon 's original redesign (which you can find HERE). Also, most of Logan's story here was cutted down (his story is long a very convoluted so I had to), so I'll mostly expand upon it on other deviations.
