Mr. M. Ister lives on the second floor of Joe Evil Zincorporated.

He is a gentleman as men go and portrays a healthy and fine mustache. Though he is not from The OK, he displays many qualities of those who originate there, and has a passion for smoking cuban cigars and general fisticuffs. He also enjoys obscure television shows, gartering their outdated terminologies for his personal use. Additionally he is very strongly against the idea of censorship.

He has had a few biographies written about him, though he said in an interview on the news that he will not allow them to be published until he dies.
