Back in the 1800s, Wolverine was a wealthy and sickly boy named James Howlett. His two best friends were a young girl named Rose who acted as his babysitter, and a boy nicknamed "Dog" Logan, who was the son of the Howlett family's gardener, who bore a striking resemblance to James as an adult. Dog's father was jealous of his son's friend's wealth, and physically abused Dog to force him not to be friends with James. Dog listened, and slit the throat of James' new puppy, causing James' father to fire Dog's. Seeking revenge, Dog and his father broke into their estate with guns and murdered Mister Howlett. The trauma of the situation activated James' latent mutation, causing claws made of bone to burst out from in between his knuckles. In a blind rage, he stabbed and killed Dog's father. Her life ruined, James' mother grabbed a gun on the floor and committed suicide. James and Rose ran away, eventually finding work at a wood mill, where James took the name Logan after the man he killed. They stayed there for years, and Logan, who was nicknamed "Wolverine" for how he worked, fell in love with Rose, who was getting engaged with the owner of the mill. Eventually, his grandfather, who was on his deathbed, decided he wanted to see his grandson, and sent Dog to go find him. Dog and Logan fought after tracking him down, and Rose was caught in the crossfire, accidentally being killed by Logan.
At a later point in time, Logan became the test subject for the secret Canadian program Weapon X. There, his memory was erased and the unbreakable metal adamantium was pumped through his body, covering his bones, including his claws. He eventually broke free and slaughtered all of the cruel workers there, escaping into the wilderness. He eventually joined the Canadian superhero team Alpha Flight under the name Wolverine, and at one point fought the Hulk. Afterwards, he left Alpha Flight and joined the second team of X-Men, a group of mutants fighting for equality. Wolverine has come to know the X-Men as his family and has remained a major member. Wolverine has also worked on other teams, such as the Avengers and the black-ops X-Force.
Wolverine has been part of the MVC roster since X-Men: Children of the Atom (1994).
