James Howlett, also known as Wolverine in the Marvel universe, was forced to abandon his family due to a tragic incident that led to him accidentally killing his own father. This event triggered his mutant abilities, causing his bone claws to pop out for the first time. In the aftermath, he ran away with his childhood companion, Rose. To hide his identity and escape his painful past, Rose gave him the name 'Logan'. Over time, James fully embraced this new identity, becoming a respected figure among miners in the Yukon Territories of Canada. His hard work and animalistic way of working earned him the nickname 'Wolverine'.
