Lee's artwork quickly gained popularity in the eyes of enthusiastic fans, which allowed him to gain greater creative control of the franchise. In 1991, Lee helped launch a second X-Men series simply called X-Men Volume 2, as both the artist and as co-writer with Claremont. X-Men Vol. 2 #1 is still the best-selling comic book of all-time with sales of over 8.1 million copies and nearly $7 million, according to a public proclamation by Guinness World Records at the 2010 San Diego Comic-Con. The sales figures were generated in part by publishing the issue with five different variant covers, four of which show different characters from the book that formed a single image when laid side by side, and a fifth, gatefold cover of that combined image, large numbers of which were purchased by retailers who anticipated fans and speculators who would buy multiple copies in order to acquire a complete collection of the covers. Lee designed new character uniforms for the series, including those worn by Cyclops, Jean Grey, Rogue, Betsy Braddock and Storm. He also created the villain Omega Red. Lee's style of rendering the X-Men was later used for the designs the television program X-Men: The Animated Series. Actor/comedian Taran Killam, who ventured into comics writing with The Illegitimates, has cited X-Men No. 1 as the book that inspired his interest in comics
