Eddie is quite silent, even though he is always there at every case with Lou and Chief Wiggum.
Eddie used to be a bit more chopsier and talked more than he does now. This is lamp-shaded in "Treehouse of Horror XV" where it is shown that Eddie rarely speaks because Wiggum cut his tongue out. While not nearly as smart as Lou, he has shown some level of competence, as during the Mr. Burns shooting, Eddie was the one to propose the idea to Chief Wiggum that they run DNA tests on the suit Mr. Burns was wearing to identify the shooter (an idea that Chief Wiggum barely came up at the same time while asleep).
Eddie has been seen in Moe's Tavern getting a drink with Lou. Also, he gave Bart a ride in the police car and tried to solve a case which Bart helped out with. He was promoted to Sergeant and asks Wiggum about who would take his position and Wiggum replies with a simple "nobody". He also once got locked in the graveyard overnight with Wiggum and Lou.
Eddie loves being a cop because it makes him feel like he is "making a difference". Eddie is yellow with lines of hair going down the sides of his face.
Treehouse of Horror
He has been seen as a musketeer, along with Lou. In another episode, he also was part of Inspector Wiggum's investigation of the Mutton-chop killer, although he is later revealed to be partly mute due to Wiggum chopping his tongue off (presumably in order to silence him from divulging Wiggum's true identity as the Mutton-chop killer due to having deduced this).
In The Simpsons Game, the Police Department gets a call in about suspicious activity at the Museum. They later check it out and find out that Principal Skinner hired the bullies to rob from it, and arrest Skinner as a result. Eddie thanks Homer for doing his job. Eddie, not long afterwards, finds out about the Duff eating contest and suddenly thinks of Homer and he is later shocked when he wins. The Police Department finds out about the new Grand Theft Scratchy game. Eddie assists the rest of the force in blocking off the town by standing in front of the school. Eddie sarcastically tells Marge and Lisa they are cool enough to cut all the way to the statue and later when Marge makes her way to the town square, the police try to protect the statue, but fail. Eddie witnesses the aliens and Lard Lad attacking the town. Due to Lard Lad attacking the Downtown area, which is heavily guarded by both it and the Mini Krustys, this prevents anyone from going to the Donut Shop or anywhere else in Downtown. Eddie thanks Homer for making it safe to go back to the Donut Shop and later questions why the police keep letting Sideshow Bob out of jail.
Behind the Laughter
Eddie has also not made many speaking appearances since the 18th season episode "Stop or My Dog Will Shoot!", in which Lou was the main character while Eddie was not, even though in Coming to Homerica, he had gout (formation of crystals in the joints causing swelling and extreme pain) in his foot, and made a few groaning sounds. In 'Chief of Hearts', when Wiggum was missing, Eddie asks Homer, "Any idea where he might be?".
