Wolverine's berserker fury is a significant aspect of his character in the Marvel universe. This rage, often triggered by intense situations, enhances his aggression and fighting skills, making him a formidable opponent. It's a reflection of his primal instincts and his struggle to maintain control over them. This fury also contributes to his reputation as one of the most fearless, brave, and dangerous men in the world. Despite his berserker rage, Wolverine is known for his loyalty and protective nature, especially towards his teammates in the X-Men and those he considers family. His berserker fury, therefore, is not just a symbol of his ferocity as a warrior, but also his passion and dedication to those he cares about.
