The mantle of Goliath has a rich and layered publication history, reflecting the evolving nature of the Marvel Universe itself. The name was first adopted not by a new character, but by an established one seeking a new identity. Dr. Hank Pym, a founding member of the Avengers, first took the name Goliath in Avengers (Vol. 1) #28, published in May 1966. Created by the legendary team of writer Stan Lee and artist Don Heck, this change was part of Pym's ongoing character arc, which was marked by feelings of inadequacy compared to powerhouses like Thor and Iron Man. Moving away from the shrinking powers of Ant-Man, Pym embraced gigantic stature, a shift that would define his character and his psychological struggles for years to come. The second character to use the name was Clint Barton, better known as Hawkeye. During a period where he had lost his bow and arrows, Barton used Pym's size-changing formula to become the new Goliath in Avengers (Vol. 1) #63 in April 1969, in a story by Roy Thomas and Gene Colan. This was a temporary but memorable phase for the character, showcasing his versatility and willingness to adapt. The most famous and enduring Goliath, Dr. Bill Foster, was introduced first as a supporting character in Avengers (Vol. 1) #32 in September 1966 by Stan Lee and Don Heck. He was a brilliant biochemist working for Tony Stark who helped Pym when he was stuck at giant size. Writer Tony Isabella and artist George Tuska later had Foster develop his own version of the growth formula, debuting him as the superhero Black Goliath in Luke Cage, Power Man #24 in April 1975. His own short-lived series, Black Goliath, launched in 1976. He would later officially shorten the name to simply Goliath, solidifying his place as a premier size-changing hero. A villainous version of Goliath emerged when Erik Josten, a mercenary previously known as Power Man, was granted size-changing powers by Baron Zemo. He took the Goliath name as part of the Masters of Evil that famously laid siege to Avengers Mansion in the “Under Siege” storyline, first appearing as Goliath in Iron Man Annual #7 (October 1984). Josten would later find a path toward redemption as a member of the Thunderbolts, changing his name to Atlas. Most recently, the legacy was passed to Tom Foster, Bill Foster's nephew. Created by writer Reginald Hudlin and artist Greg Pak, Tom first appeared in Black Panther (Vol. 4) #23 in February 2007. After his uncle's death in Civil War, a furious Tom replicated the Goliath formula and took on the mantle to seek justice, and at times vengeance, for his family.
The origin of Goliath is not a single event, but a series of stories detailing how different individuals came to possess and utilize the power of Pym Particles to become giants among heroes.
The legacy of Goliath in the prime Marvel Universe is a complex tapestry woven from scientific ambition, personal crisis, heroic succession, and even villainous appropriation.
Dr. Henry “Hank” Pym, a brilliant but deeply insecure scientist, was the first to adopt the Goliath persona. After years of operating as Ant-Man and later Giant-Man, Pym began to feel overshadowed by his more powerful teammates on the Avengers. Believing his shrinking abilities were no longer effective or respected, he developed a new application of his revolutionary Pym Particles that allowed him to grow to immense heights while retaining his full strength and density. He debuted his Goliath identity during a conflict with the villainous Collector. This shift, however, came at a great psychological cost. The process of rapid growth and the stress of his superhero life exacerbated his existing mental health issues, leading to erratic behavior and a notable identity crisis. He would cycle through other identities, including Yellowjacket, before eventually returning to his roots as Ant-Man and Giant-Man, but his time as Goliath remains a critical, albeit tumultuous, chapter in his history. It represents his desperate attempt to measure up, a theme that would define his character for decades.
Clint Barton's tenure as Goliath was a direct result of circumstance. After his signature bow was destroyed during a crucial battle, the master archer felt useless on a team of gods and super-soldiers. Seeking a way to contribute, he approached his friend Hank Pym. With Pym having recently abandoned the Goliath identity for that of Yellowjacket, the growth serum was available. Barton, ever the risk-taker, willingly subjected himself to the treatment and became the second Goliath. His time as a giant was marked by a brawling, less scientific approach to the powers. He was a natural athlete, and he adapted his fighting style to his newfound size, but he lacked Pym's deep understanding of the underlying science. This phase was crucial for Clint's development, forcing him to define his heroism outside of his archery skills. He eventually returned to the role he was born for, Hawkeye, but his stint as Goliath is a testament to his adaptability and commitment to the Avengers' cause.
Dr. William “Bill” Foster is, for many, the definitive Goliath. His journey began as a brilliant biochemist working at Stark Industries, where he was tasked with helping Hank Pym, who was trapped at a height of 10 feet. Working alongside Pym, Foster not only succeeded in curing him but also became a close friend and confidant. Intrigued and inspired by Pym's work, Foster later moved to the West Coast and, working independently, developed his own unique variant of the growth formula, free of some of the side effects that plagued Pym. He initially debuted as “Black Goliath,” a name he chose to inspire the African-American community. As a hero, he was a force for good, a brilliant mind with immense power, driven by a profound sense of responsibility. He served with distinction on teams like the Champions of Los Angeles and the Defenders, and he was a core member of Project: PEGASUS's scientific staff. Over time, he dropped the “Black” from his moniker, becoming known simply as Goliath, cementing his status as a standalone hero. Unlike Pym's internal turmoil or Barton's temporary adoption, Bill Foster was Goliath—a stable, compassionate, and powerful hero who embodied the mantle's full potential.
The Goliath name was corrupted when it was stolen by the mercenary Erik Josten. Originally a smuggler empowered by Baron Heinrich Zemo and known as Power Man, Josten was later recruited by Zemo's son, Baron Helmut Zemo, into a new incarnation of the Masters of Evil. Using technology and research stolen from Pym and Foster, Zemo's scientists (notably Fixer) imbued Josten with the ability to grow to giant size. Josten took the name Goliath and became the muscle for the Masters of Evil during their infamous siege of Avengers Mansion. He was a brutal, thuggish giant who reveled in his power, a dark mirror to the heroic men who held the title before him. His path would eventually lead him to the Thunderbolts, a team of villains posing as heroes. Under this new banner, and the new name Atlas, Josten began a long and difficult journey toward redemption, but his time as the villainous Goliath left a stain on the heroic legacy.
The most recent Goliath is Tom Foster, the nephew of Bill Foster. Tom idolized his uncle and was pursuing a similar path in science. His life was shattered when he watched his uncle be brutally murdered on national television by the rogue Thor clone, Ragnarok, during the Superhuman Civil War. Consumed by grief and rage, Tom dedicated himself to avenging his uncle's death. He publicly condemned Reed Richards and Tony Stark for their role in creating the clone. He eventually managed to isolate and ingest a refined version of his uncle's Pym Particle formula, gaining the same size-shifting powers. Calling himself Goliath in his uncle's honor, he joined Captain America's Secret Avengers to fight against the Superhuman Registration Act, driven by a burning desire to make Stark and his allies pay for what they had done.
The Marvel Cinematic Universe (designated as Earth-199999) takes a significantly different approach to the Goliath legacy, re-imagining it as a scientific project rather than a public superhero mantle. In the film Ant-Man and the Wasp, Dr. Bill Foster (portrayed by Laurence Fishburne) is introduced as a former colleague of Hank Pym and Janet van Dyne at S.H.I.E.L.D.. Together, they worked on “Project Goliath,” an initiative aimed at safely harnessing Pym Particles for large-scale size manipulation. Foster served as Pym's assistant, and flashbacks reveal that he successfully used a specialized suit to grow to a record height of 21 feet. However, a fierce ideological disagreement over the potential weaponization of their technology caused a bitter falling out between the two scientists, ending their partnership. Decades later, Foster became a professor of quantum physics at UC Berkeley and a surrogate father to Ava Starr, the daughter of another disgraced colleague, Elihas Starr. After a quantum accident left Ava in a state of “molecular disequilibrium,” phasing in and out of reality as the antagonist Ghost, Foster dedicated his life to finding a cure for her. The MCU's Bill Foster is not a superhero. He is a brilliant but disillusioned academic, haunted by his past and driven by a paternal love for his surrogate daughter. While he possessed the ability to become a giant, it was only in a controlled, experimental setting. The “Goliath” name refers to the project, not a public identity. This adaptation grounds the concept in the more clandestine world of S.H.I.E.L.D. espionage and scientific rivalries, providing a rich backstory for the film's antagonists and creating a compelling personal conflict with Hank Pym. It serves as a narrative foil, exploring what could have happened if Pym's technology had been developed under a different philosophical lens.
The powers of every Goliath stem from the same source, but their application, limitations, and the personalities wielding them differ significantly.
The MCU's depiction of Goliath's abilities is more grounded in the context of advanced, semi-stable technology.
During this galaxy-spanning conflict that threatened to engulf Earth, Clint Barton was operating as Goliath. His immense size and strength were a critical asset for the Avengers, both on Earth and in space. A key moment saw Goliath, along with Captain America, Quicksilver, and the Scarlet Witch, captured by the alien Skrulls. Later, he was part of the away team that journeyed into the body of the android Vision to repair him. Barton's participation as Goliath demonstrated that even without his bow, he was an indispensable Avenger capable of fighting on an epic scale.
Bill Foster's time as a founding member of the Champions was a defining period for his character. The team's formation was haphazard, bringing together a disparate group of heroes who didn't quite fit the mold of the Avengers or Fantastic Four. As Black Goliath, Foster was often the scientific mind and the moral center of the group. The series explored his life as a hero balancing his scientific career with his costumed adventures on the West Coast, solidifying him as a standalone character and not just an extension of Hank Pym's legacy.
This is the single most important storyline for the Goliath legacy. When the Superhuman Registration Act was passed, Bill Foster refused to comply, viewing it as a dangerous infringement on civil liberties. He joined Captain America's Secret Avengers and became one of its most powerful and outspoken members. During a confrontation between the two factions, the pro-registration side unveiled a secret weapon: a clone of Thor, code-named Ragnarok, created by Tony Stark, Reed Richards, and Hank Pym. In the ensuing battle, the unstable clone targeted Bill Foster. It fired a blast of lightning directly through Goliath's chest, killing him instantly. Bill's death was the war's first major casualty and its point of no return. It horrified both sides, causing some heroes like Sue and Johnny Storm to defect to Captain America's side. His last words, “They've killed me,” were broadcast on national television, turning him into a martyr for the anti-registration cause. The event cemented Bill Foster's status as a true hero and remains one of the most shocking and impactful deaths in Marvel history.
