Wolverine is a fictional superhero appearing in American comic books published by Marvel Comics. The character was created by writer Len Wein and Marvel art director John Romita Sr., who designed the character's iconic costume, with artist Herb Trimpe providing the first interior artwork. Wolverine made his debut in the final panel of "The Incredible Hulk" #180, dated October 1974, and had his first full appearance in the following issue.
Born James Howlett in late 19th-century Canada, Wolverine is a mutant possessing animal-keen senses, enhanced physical capabilities, a powerful regenerative healing factor, and three retractable bone claws on each hand. His skeleton was later bonded with the indestructible fictional metal adamantium during the Weapon X program, a traumatic event that erased much of his memory and turned him into a living weapon. The character is defined by his gruff, loner personality, a fierce sense of honor, and a berserker rage that makes him one of Marvel's most dangerous fighters.
Wolverine quickly became one of the most popular and commercially successful Marvel characters. After his introduction, he joined the X-Men in 1975 as part of the team's international relaunch in "Giant-Size X-Men" #1, written by Wein and drawn by Dave Cockrum. His mysterious past, antihero attitude, and complex moral code set the template for a new generation of comic book protagonists, moving away from the clean-cut heroes of earlier decades.
Over the decades, Wolverine has starred in multiple solo comic series, one-shots, and graphic novels, including the landmark 1982 limited series by Chris Claremont and Frank Miller that solidified his samurai-inspired ethos. He has been a core member of numerous Marvel teams including the X-Men, X-Force, and the Avengers, and his popularity has extended far beyond comics into animation, video games, and a massively successful film franchise.
