He is known for his roles as Buster Bunny on Tiny Toon Adventures, the Bigheads (Ed and Bev) on Rocko's Modern Life, Ickis on Aaahh!!! Real Monsters, Doctor Doom, Wrecker, Sabertooth and others in The Super Hero Squad Show, MODOK in various Marvel media, Cobra Commander in GI Joe: Resolute and Renegades, Starscream in the Transformers films, Mr. Whiskers in Brandy & Mr. Whiskers, Cow, Chicken and the Red Guy in Cow and Chicken, Professor Monkey-for-a-Head in Earthworm Jim, I.R. Baboon in I Am Weasel and T-Bone in SWAT Kats: The Radical Squadron.^[2][3]

In the mid-1960s, Adler's family moved to Nanuet, New York and later to Massachusetts. He was given the nickname "Beanie" due to always wearing a Beanie cap. His sister Cheryl Adler is a psychotherapist who wrote the book Sober University.

Growing up, Adler was a self-described "TV junkie",^[4] and an avid fan of Rocky and Bullwinkle, The Three Stooges and Irene Ryan's Granny Moses from The Beverly Hillbillies.

Adler's first professional acting job was in a commercial in 1971.^[1][5] Afterward, he took a hiatus from acting.^[5] During this time, he worked a variety of jobs, including waiter, janitor, paper delivery man, floor stripper, house painter, remedial reading teacher and caretaker for an Episcopal church.

In 1984 and 1985, he starred as Arnold Beckoff in Torch Song Trilogy, for which he was nominated for the 1985 Helen Hayes Best Actor Award, in New York City before moving to California in 1986.^[4][6]

Adler's first animation role was recorded in New York City, voicing Spike in Rescue at Midnight Castle.^[7]

In 1985, after convincing the head of the Abrams, Rubiloff and Lawrence agency to allow him to audition for their voice-over department,^[7] Adler later attended a private audition for Ginny McSwain and Arlene Thornton. An agent had praised him in front of them as the "next Frank Welker".^[8] McSwain recalls that "he blew their minds"^[8] but he claims that initially they had no interest in him. Having no demo, they arranged for him to record an audition. He improvised characters during the tape, which impressed both McSwain and Thornton; however, Adler was so embarrassed with his performance that he performed with his back to them and his face hidden with a hat and sunglasses.^[4]

His voice acting career took off when Adler landed the roles of Nat Smurfling in the fourth season of The Smurfs, "Rowdy" Roddy Piper on Hulk Hogan's Rock 'n' Wrestling, Silverbolt on The Transformers and Eric Raymond, Techrat and Zipper in Jem.

He was disenchanted with live-action acting after working on The Redd Foxx Show, in which he portrayed Ralph/Rita. In an interview for The Magic Behind the Voices, Adler commented on the experience: "you spend your whole life going, "God, I just want to be in a TV show and have a parking space". Then I got it and it was just so not what I wanted to do."^[4]

He became active in animation, his roles include reprising Spike on My Little Pony, Low-Light on G.I. Joe, Mr. O'Greasy on A Pup Named Scooby-Doo, Deputy Fuzz and Tex Hex on Bravestarr, Cavey Jr. on The Flintstone Kids, Pinky Dalton on The Good, the Bad, and Huckleberry Hound, Quark and Zappy on Rockin' with Judy Jetson, the TurkeyBoy and sometimes Hamburglar in McDonald's commercials and The Wacky Adventures of Ronald McDonald, Mad Dog, Hacksaw, and Howard Huge in TaleSpin, Dripple on Tom and Jerry Kids, and the titular character on Paddington Bear.

In 1990, Adler lent his voice to Buster Bunny on Tiny Toon Adventures.^[6] Producer Tom Ruegger recalled that he and voice director Andrea Romano insisted Steven Spielberg cast him due to the "great deal of energy" he brought to Buster. In 1992, during the show's third season, he abruptly left the show after a disagreement with the producers; while voice actors with smaller roles in the show were given starring roles in its successor Animaniacs, he was offended when he was not offered a role in that series. John Kassir replaced him for the remainder of Tiny Toons.

In 1993, Adler went on to play Chance "T-Bone" Furlong on SWAT Kats: The Radical Squadron, Bill on The Terrible Thunderlizards, Ickis on Aaahh!!! Real Monsters, Ed and Bev Bighead on Rocko's Modern Life, Stalker Slaughter on Captain Planet and the Planeteers and Screwball Squirrel, as well as reprising Dripple for Droopy, Master Detective.^[4]

In 1995, Adler voiced several characters on What a Cartoon!. In the latter, he played Cow, Chicken and The Red Guy. No Smoking was a pilot created by David Feiss, which was greenlit to be a series in 1997 with him on board to reprise his characters, for a new series, titled I Am Weasel. Cow and Chicken ran from 1997 to 1999, receiving multiple awards and nominations, including an Annie Award for "Outstanding Individual Achievement for Voice Acting in an Animated Television Production" for Adler as Cow. Later on I Am Weasel was made into a spinoff series, in which he reprised the three characters and also voice I.R. Baboon.

His voice directing career began in the late 1990s with Rugrats^[9] and later collaborated with Klasky Csupo. Adler has directed The Wild Thornberrys, Rocket Power, All Grown Up!, The Marvelous Misadventures of Flapjack, The Replacements, among others.^[10]

In 2007, Adler provided the voice of Starscream in Michael Bay's live-action Transformers film franchise. Just as Chris Latta voiced both Starscream and Cobra Commander^[11] in the Sunbow cartoons, Adler voiced Cobra Commander on G.I. Joe: Resolute and G.I. Joe: Renegades. He also voiced the titular character in the webtoon Inspector Beaver.
