Wolverine is a fictional character that appears in comic books published by Marvel Comics. The character first appeared in Incredible Hulk #180 (October 1974) and was created by writer Len Wein and Marvel art director John Romita Sr., who designed the character, and was first drawn for publication by Herb Trimpe.
Wolverine later joined the X-Men's "All New, All Different" roster in Giant-Size X-Men #1 (May 1975). In May 2008, Wolverine was ranked # 1 out of "Wizard Magazine's Top 200 Comic Book Characters of All Time". X-Men writer Chris Claremont played a significant role in the character's subsequent development as well as artist/writer John Byrne, who insisted on making the character older than the other X-Men.
Frank Miller also helped to revise the character in the early 1980s with the eponymous limited series in which Wolverine's catch phrase, "I'm the best there is at what I do, but what I do isn't very nice", was first written.
In May 2008, Wolverine was ranked #1 out of "Wizard Magazine's Top 200 Comic Book Characters of All Time" and was ranked #4 of "The 50 Greatest Comic Book Characters" by Empire Magazine in July 2008.
