Melvin is a member of The Nega M-san Bunch. He claims that he's the g*yest atagonist from Yu-Gi-Oh!, while it's actually debatable. His s*x slaves named Steve are also Nega M-san Bunch members. By the way, could you give him a hug? The actual reason why he joined, is likely due to Marik being in The M-san Bunch.

Melvin having an org*sm

Also, Melvin would have given all of The Nega M-san Bunch members "free hugs", should he and/or his minions be unable to join.
