Dee Dee is one of the main villains in the series, along with Joey and Marky. He is named after the bassist of the punk rock group The Ramones, Dee Dee Ramone.
Dee Dee is an ever-hungry, devour-it-all roach. He is presumably the youngest of the roaches as he acts somewhat childish. His appetite sometimes reaches insane regions, often resulting in the consumption of larger animals or other things (such as a hyena in one case and due to the effects of a poisonous mushroom in another case, an insect. He has even tried to eat elephants, Oggy, Jack and a boar). He is usually the bravest of the group as he is seen even tackling larger animals like a penguin for its egg, an octopus for its arm and a herd of elephants so it can eat one of them even though his efforts are usually wasted as he gets beaten up.
He is a blue-bodied, orange-headed roach with green eyes. He is quite overweight and also is strong for a cockroach, being able to lift up the other cockroaches and also heavy things for a cockroach easily.
