Fictional character biography
Early years
Wolverine suffered from amnesia. As a result, what little was known about his early life was both suspect and unverifiable. It is believed that, at one point, Wolverine had a wife or girlfriend, but she was supposedly murdered by Sabretooth. As both Wolverine's and Sabretooth's memories had been tampered with in the past (most commonly by the Weapon X), this claim was highly suspect; however, Wolverine did own a wedding ring that served as his only link to his past. He also owned dogtags. One side read 'Logan' and the other side 'Wolverine'.
Captain America recognized Wolverine as James Howlett, a paratrooper he had made several jumps with during World War II. He was called "Lucky Jim" because he always survived, no matter how gravely he was injured. Dum-Dum Dugan also recognized him as Jim although how he knew him has not yet been specified.
