|Mandrill appears in Defenders No. 91 (among other issues)|
I always liked Marvel Comics Mandrill. He fought the Defenders more than once and was one of my favorite Defenders villains. I believe it was Defenders No. 91. They fought the Mandrill and the cover has Hellcat sparing with Valkyrie. This is one of the best Defenders issues, in my opinion.
