Wolverine's violent nature, often manifesting as a berserker fury, has earned him a dual reputation as both a formidable superhero and a lethal killer. This dichotomy is a defining aspect of his character. Despite his aggressive behavior, Wolverine has proven to be a valuable member of superhero teams like the X-Men and the Avengers. However, his readiness to employ lethal force and his willingness to permanently deal with adversaries have also made him one of the most feared and dangerous men in the world. His violent tendencies have often put him in conflict with his teammates, particularly those who advocate for less violent solutions. Yet, over time, Wolverine has grown fond of his fellow superheroes, considering them his new family. His violent nature, combined with his bravery and fearlessness, make Wolverine a complex and intriguing character in the Marvel universe.
