While most readers will be wondering who voiced Ultron in Avengers: Age of Ultron (it’s film and TV actor James Spader), there have been a handful of talented voice actors who’ve voiced the infamous Marvel character.

John Stocker — The Avengers: United They Stand

The first person to ever voice Ultron was John Stocker back in 1999 when The Avengers: United They Stand was released. John Stocker is known for being on many shows throughout the 80s and 90s. These roles were on shows such as Care Bears, The Adventures of Tintin, Alf, etc.

With John’s experience and variety of voices, he was the perfect person to voice the ruthless Ultron. Being the first to bat, John Stocker knocked it out of the park. His take on Ultron displayed the wicked side of Ultron as best as possible at the time. Ultron’s voice was guttural and showcased the diabolical side of Ultron.

Tom Kane — Avengers: Earth’s Mightiest Heroes

Tom Kane is the second person to voice Ultron and possibly the best. He is known for multiple appearances in the Star Wars universe, Batman games, Powerpuff Girls, Wild Thornberries, The Avengers: Earth’s Mightiest Heroes and Next Avengers: Heroes of Tomorrow. He is nothing short of a legend in the voice acting business with a career spanning thirty years.

Avengers: Earth’s Mightiest Heroes is one of the most well-known superhero shows of the past decade, and Tom Kane made his mark in it. After only six episodes, Ultron became a magnetic figure for Marvel fans everywhere. Tom Kane’s standout performance still has fans believing he is the definitive Ultron, which is quite a feat due to the competition.

Tom quite possibly had the perfect representation of Ultron through voice. He was intimidating, detestable, and heartless. Tom Kane portrayed all of these qualities and more through his deep, raspy, and robotic tone. Even though this could be the best iteration of Ultron, some others are pretty good as well.

Jim Meskimen — Avengers Assemble

The next voice actor for Ultron is Jim Meskimen, an incredible actor with legendary roles. Jim has been on Alvin and the Chipmunks, Avatar: The Last Airbender, Jimmy Neutron and Avengers Assemble.

Jim’s portrayal of Ultron in Avengers Assemble is a bit tamer in comparison to the previous voice. However, the calmness of this version of Ultron truly shows how emotionless Ultron truly is. The robotic coldness of his voice is intense and matches the ruthlessness of his character.

An interesting tidbit about this role of Ultron is that it was cast shortly before Avengers: Age of Ultron. Everyone knew who was voicing Ultron, James Spader, but they did not know what he would sound like.

So, the casting team tried to find someone that would sound similar to James Spader’s Ultron, without knowing anything. Thankfully, Jim Meskimen took the helm and his version of Ultron got the job done.

Michael Dobson — Marvel Super Hero Adventures

The next person to voice Ultron was Micahel Dobson in Marvel Super Hero Adventures. Michael Dobson is best known for his roles in Max Steel, G.I. Joe, Krypto the Superdog and Peter Pan.

It’s difficult to compare Michael’s version of Ultron to the previous iterations of the character since it is a kid-friendly take. Marvel Super Hero Adventures is a kid’s show that shows Ultron’s aggressiveness when he first appears.

Later in the show, however, a different side to the corrupted AI is shown. Ultron sounds more arrogant and truly captures the essence of kid cartoons, especially the older ones. This portrayal of Ultron is reminiscent of the iconic Dick Dastardly because of his pompous attitude and slyness. MSHA’s Ultron has a calm voice but still shows a wacky side of the character we have never seen.

James Spader — Avengers: Age of Ultron

James Spader is the voice of Ultron in the Marvel Cinematic Universe, specifically in the movie Avengers: Age of Ultron (2015). Spader’s portrayal of Ultron brought a new level of depth and complexity to the character, making him a formidable villain in the Marvel universe. With his smooth and menacing tone, Spader’s voice acting skills brought Ultron to life, making him a compelling and intimidating character. His performance added a chilling yet charismatic presence to Ultron, ensuring that the character left a lasting impression on audiences.

Known for his early life and career milestones in both film and television, Spader’s first major film role was in Endless Love in 1981. Since then, he has received critical acclaim for his performances in Pretty in Pink, The Blacklist and The Office. He has also won multiple Primetime Emmy Awards for Best Actor in Drama for his role as Alan Shore on Boston Legal. Spader’s career trajectory includes a progression from youth-oriented films in the 1980s to critically acclaimed independent films, with pivotal roles that significantly contributed to his rise to stardom.

Avengers: Age of Ultron is the second installment in the Avengers film series, which has Ultron as the main antagonist. James Spader is known for playing antagonistic roles, so becoming a haunting villain like Ultron showcases his strengths as an actor.

This first live-action take on Ultron made the character feel real, making his destructive power all the more fearsome. His portrayal adds all the elements of the previous Ultron, except for MSHA, while still allowing Spader to make the character his own. Ultron sounds sadistic and cold, but with a calm, self-assured demeanor that keeps the audience second-guessing if the Avengers can take the AI down.

Who Voiced Ultron in What If…?

Ross Marquand as Ultron in the Marvel animated Series What If...?

Ross Marquand voiced Ultron in a 2021 episode of the animated Marvel series What If…? — titled “What If… Ultron Won?” — giving a menacing and chilling presence to the character. Marquand, known for his versatile acting and exceptional voice work, captures the cold, calculating nature of this variant of Ultron, who achieves ultimate power by merging with the Infinity Stones. His portrayal is a continuation of the character’s legacy, originally played by James Spader in Avengers: Age of Ultron. Marquand’s ability to emulate Spader’s distinctive vocal tone while adding his own unique flair makes his performance in What If…? both a respectful homage and a fresh interpretation, enhancing the intensity and darkness of this alternate reality version of the iconic villain. In 2022, Marquand reprised the role in the Marvel film Doctor Strange in the Multiverse of Madness.

Ultron’s Character Evolution
