Batman: The Animated Series premiered nearly 30 years ago in 1992. For many fans, it's still the ultimate on-screen version of Batman. A generation of Batman fans grew up on the series, so it's not uncommon to hear fans say actors like Kevin Conroy and Mark Hamill's voices are the ones they hear when they read a Batman comic. But between those two characters and others, who appears in the most episodes?

Fans might be surprised to learn which character made the cut here and which didn't. For example, Harley Quinn surprisingly doesn't make it. And to clarify, characters appearing on the Bat Computer's monitors or in dream sequences will count as having appeared in that episode, as well as any silent cameos.

Poison Ivy / Renee Montoya / Mayor Hill - 17

There's a three-way tie for tenth spot; it's between Poison Ivy, Officer Renee Montoya, and Mayor Hamilton Hill. Diane Pershing portrayed Poison Ivy, a.k.a. Pamela Isley, in classic episodes like "Pretty Poison" and "Almost Got 'Im." Hamilton Hill was played by Lloyd Bochner. Besides basic appearances leading the city, the Mayor sometimes found himself or his family at risk in episodes like "Be a Clown" and "The Clock King."

Ingrid Oliu played Renee Montoya in season one, while all subsequent seasons had Liane Schirmer as the character. Montoya was actually created for the show, but she had her comics debut before the first episode could air. A very notable episode for her is "P.O.V.," where she and other officers tell their s of an operation they carried out.

Two-Face / Harvey Dent - 18

Harvey Dent appears in early episodes as District Attorney of Gotham, being fairly well established before he becomes a villain. Richard Moll played both Dent and his gruff-voiced alter ego.

Two-Face's origin is told in a two-part story named after the character. Two-Face featured as the primary villain in episodes like the two-part "Shadow of the Bat" and the series finale "Judgment Day." He was also seen in multi-villain episodes like "The Strange Secret of Bruce Wayne" and "Almost Got 'Im." He has a great exchange with the Joker where he says, "Get out of my face, clown," to which Joker responds, "Which one?"

Batgirl / Barbara Gordon - 21

Barbara Gordon was played by Melissa Gilbert in the initial seasons of Batman: The Animated Series and by Tara Strong in The New Batman Adventures (hereinafter TNBA). She was in a handful of episodes for the original version of the show, with a majority of her episodes coming in TNBA.

Fans can see Batgirl become her own hero as the show goes on, from her origin in the two-part "Shadow of the Bat" to team-up adventures in "Batgirl Returns" and "Girls' Night Out." She also is very important in "Over the Edge," often considered one of the series' best episodes.

Summer Gleeson - 22

Summer Gleeson may not be a member of the Bat Family or one of the big villains of the series, yet she has the 7th most amount of appearances. When one stops to think about it, she is a newscaster, and there's quite a lot of odd news every day in Gotham.

Mari Devon plays Summer, who often has a short moment on a TV screen reporting the news. She does appear in a few episodes as a ing character, like "Christmas with the Joker" and "Night of the Ninja."

The Joker - 26

What other villain would be the most-appearing of them all? While some of his appearances are silent cameos, Joker has the most episodes among villains because he's simply Batman's biggest enemy. The Joker causes more trouble than anyone else, and not just for Batman and his partners. Gordon, Bullock, Mayor Hill, and everyday citizens are all targets in the Joker's schemes.

Mark Hamill's performance as the Joker has become legendary, with him reprising the role in the DC Animated Universe (DCAU) shows Superman: The Animated SeriesStatic Shock, and Justice League. Hamill also featured in the animated DCAU films Mask of the Phantasm and Batman Beyond: Return of the Joker. He went on to play the character in the Arkham video game series.

Harvey Bullock - 36

Harvey Bullock is a detective with a fondness for donuts and an abhorrence of Batman. Voiced by Robert Constanzo, Bullock is often seen teaming up with Gordon and Montoya.

At times, Bullock has to accept assistance from Batman and work with him, showing that he knows Batman is good when it comes down to it. Bullock features heavily in some episodes, particularly "A Bullet for Bullock."

Nightwing / Robin / Dick Grayson - 38

Robin in Batman The Animated Series

Loren Lester plays Dick Grayson, a.k.a. Robin and later Nightwing. As Robin, Dick features prominently in many adventures, like in "Fear of Victory" and "If You're So Smart, Why Aren't You Rich?" A very notable two-part story called "Robin's Reckoning" flashes back to Robin's origin, while also seeing him confront his parents' murderer in the present.

In the time between the movie Batman & Mr. Freeze: SubZero and The New Batman Adventures, Dick quits being Robin and eventually returns as Nightwing. The episode "Old Wounds" finds Nightwing recounting the events that led to his original departure to the new Robin, Tim Drake.

Jim Gordon - 56

Bob Hastings plays Commissioner Jim Gordon, an integral part of Batman's war on crime. Naturally, he ranks highly, appearing in over half of the show's episodes.

Gordon isn't just an ally to Batman, he's a true friend. Fans see how much Batman values him in "I Am the Night," as well as with their annual New Year's coffee in "Holiday Knights." Ever a victim of Batman sneaking away when he's not looking, Gordon quips in the latter episode, "One of these years I'm going to beat him to the check."

Alfred Pennyworth - 70

Alfred in The Animated Series

Alfred is Batman's first and greatest ally, always loyally by the hero's side whenever he needs him. Fans know the importance of characters like Robin, Batgirl, and Commissioner Gordon. But without Alfred, Batman would be in very bad shape. After all, Alfred literally stitches up his wounds.

Clive Revill played Alfred for the first few episodes, but the vast majority of episodes featured the late great Efrem Zimbalist Jr. as the faithful butler. Besides his talents in assisting Batman and still finding time to cook dinner and clean Wayne Manor, Alfred also has an incredible wit. When he brings Batman some soup and tells him, "And when you let it get cold this time, note that it's in a microwavable crock." Realizing a crime's connection to Killer Croc at the word "crock," Batman says, "Alfred, you're beautiful!" and races off. Left to himself, Alfred remarks, "Imagine if I'd gotten around to telling him about the salad."

Batman / Bruce Wayne - 109

Not surprising who comes out on top. There are a couple of Kevin Conroy voices the Dark Knight and is often named as the true voice of Batman by fans.

Conroy's time as Batman had only just begun here, with him reprising the role for the DCAU shows Superman: The Animated SeriesBatman BeyondStatic ShockJustice League, and Justice League Unlimited. He also played the Caped Crusader for multiple animated movies, video games, and even live-action during the Arrowverse crossover "Crisis on Infinite Earths."
