Cockrum then revamped a few of the characters with Len Wein to make them the new X-Men in the All-New, All-Different X-Men. However, one of the characters was so perfectly designed that they just adopted him wholesale. That was Nightcrawler, whose circus-esque costume perfectly fit the carefree personality that Cockrum and Wein came up with the for character in the X-Men. It is the perfect swashbuckling outfit. The X-Men seem to go through more costume re-designs than any other team of heroes and yet Nightcrawler's costume has mostly remained unchanged for over 40 years.
Mike Zeck came up with the actual look and it is a stunning piece of design. All black except for the prominent white spider. Rick Leonardi also did some tweaks to the costume and it soon became the most controversial, yet surprisingly popular costume change in comic book history. Fans were aghast at first but then really started to enjoy the new look. Eventually, the design was adapted for the villain Venom, with Spider-Man returning to his classic look. It is popular enough, though, that it still makes occasional comebacks.
