Marky is suave, often not really caring about what the two roaches others are doing. He is the middle child. While he originally used to love causing mischief just like the other cockroaches, he has grown to be more laid-back in later episodes, though he still enjoys hanging out with Joey and Dee Dee and cause general mayhem like he has always done. His hobby is dating girls - even puppets - and reading books. He also has bad breath, as revealed in the episode It's a Small World and Itsy-Bitsy Oggy (how he can stand his own bad breath is debatable, as he couldn't stand the smell of gas in French Fries.)
Not very intelligent, Marky is unable to take the slightest initiative, but he is an enthusiastic participant in each of Joey's plans. A limp dishrag, totally lethargic, this guy's laziness is almost as great as his stupidity. It's hard to say how he could possibly be dangerous... except that when you think about it... Marky follows. If Joey is devising a devilish plan, then Marky is involved.
Long, tall, skinny Marky is second-in-command. Not exactly gorgeous, although he is reputed for past success in that domain. Difficult to believe that now. Maybe when he was young, who knows…
