The Super-Soldier Serum is one of Marvel Comics’ most ingenious ideas with everyone from Captain America to Man-Thing having some history with the formidable formula. Over the years, many have tried to replicate this vaunted serum with results that range from inspiring to horrifying and everywhere in between.

And while turning scrawny Steve Rogers into the Sentinel of Liberty was one of the more notable applications of this serum, Captain America is far from the only Super-Soldier success story.

Created by Ed Brubaker & Steve McNiven

Marvel Codename Bravo

An ally turned enemy of Captain America himself, the enhanced operator known as Codename: Bravo was an old wartime ally of Rogers, along with Nick Fury and Peggy Carter, until a failed mission left him stranded in another dimension. While the results of his own Super-Soldier Serum variant don’t quite put him at Rogers’ level, he’s still twice as strong, fast, and coordinated as any Olympic athlete.

These enhancements, along with his notable prowess as a hand-to-hand combatant and marksman, make Codename: Bravo a formidable force against anyone unfortunate enough to get in his way – even Captain America himself.

Marvel Captain Midlands

The British equivalent of Captain America, Sid Ridley may be obscure, but his status as a super soldier cannot be denied. Enhanced with the British variant of the Super-Soldier Serum, Ridley performed at peak human capacity with physical capabilities that would sur any Olympic athlete.

Unlike his iconic American counterpart, Captain Midlands was never frozen for decades, aging much more slowly than any normal human following the war. Prior to his death, Ridley maintained a startling degree of near-superhuman competence, looking no older than 60 and functioning as a much younger super soldier operative despite being in his 80s.

13 Taskmaster/Tony Masters

Marvel's Taskmaster in a black-and-orange variation on his classic costume.

Anthony Masters is by and large one of Marvel’s most popular mercenaries, but his status as a super soldier is one that many fans may not have been aware of. Born with the natural ability to duplicate any movements he sees, Masters’ photographic reflexes were further enhanced after injecting himself with a Nazi version of the Super-Soldier Serum.

While this serum didn’t do much to elevate his strength, it did boost his speed and reflexes to near-superhuman levels and better acclimate his body for replicating any physical feat he encounters – making Taskmaster one of the most dangerous super soldiers out there.

12 Patriot/Eli Bradley

Created by Allan Heinberg & Jim Cheung

Marvel Patriot

The grandson of Isaiah Bradley, one of the first successful Super-Soldier Serum recipients, the Young Avenger known as Patriot didn’t reach super soldier status until receiving life-saving blood transfusion from his grandfather. Exposure to the latent serum within his grandfather’s blood heightened Bradley’s strength, speed, and durability to peak human levels – also granting him immunity to practically all Earthly diseases and toxins.

Marvel fans are abuzz over a suggested Young Avengers series coming 2025, but later clarifications make it clear that's not quite what's coming.

Able to lift up to 800lbs and run at speeds reaching 35 mph, combined with his now peak human intelligence, Patriot is one of the most capable young heroes out there, and a worthy inheritor of his grandfather’s heroic legacy.

11 Destroyer/Kevin Marlow

Created by Stan Lee & Jack Binder

Marvel Destroyer Kevin Marlow

The super soldier known as Destroyer, American reporter, Kevin Marlow, gained his peak human abilities after ingesting a variant of the Super-Soldier Serum created by one of Abraham Erskine’s successors while imprisoned in Nazi . This variant greatly augmented Marlow’s strength and speed, allowing him to lift approximately 1,000 lbs and run up to 30 mph.

As the Destroyer, Marlow took the battle to the Axis powers and even remained a government agent after the end of World War II. His aging process also slowed by the Serum, Marlow remained a capable fighter and super soldier into his 80’s before ing on the mantle to a successor.

One of the great unsung heroes of the Marvel Universe, Isaiah Bradley became a super soldier after he and 300 other African American soldiers were forcibly recruited as test subjects in a gruesome experiment to recreate Captain America’s Super-Soldier Serum after the death of Dr. Erskine.

The most successful recreation resulting from the project, Bradley’s enhanced physiology made him an incredibly formidable force capable of lifting over 1,000 lbs and reaching speeds up to 40 mph. ing these abilities down to his son, Josiah X, and later his grandson, Patriot, via blood transfusion, the painful past of “The Black Captain America” paved the way for a new generation of heroism.

9 Captain America/Steve Rogers

Created by Joe Simon & Jack Kirby

Captain America Alex Ross Art

The most famous recipient of the Super-Soldier Serum, Captain America is one of Marvel’s most iconic heroes and one of humanity’s most impressive physical specimens. Capable of overhead lifting 800 lbs and bench-pressing 2,200 lbs as a simple warm-up, Rogers’ strength is the pinnacle of human capability with a potential for speeds of up to 60 mph.

Rogers’ stamina and durability are equally upgraded, allowing him not only to survive decades frozen in suspended animation, but the various injuries he’s received not just as a soldier in World War II, but as a hero and Avenger since his revival in the modern age.

8 Protocide/Clinton McIntyre

Created by Dan Jurgens & Andy Kubert

Captain America vs Protocide

A recipient of Steve Rogers’ same Super-Soldier formula, Clinton McIntyre was a believed by a rogue general to be a superior physical specimen more deserving of the Super-Soldier Serum than Rogers. Dying after his superior botched an incomplete super-soldier enhancement process, McIntyre was eventually resurrected by A.I.M. to menace Cap and his allies.

There have been tons of Captain America villains, but there are still three major ones that the MCU has yet to bring to the big screen.

Despite receiving the same formula as Rogers, Protocide’s physical capabilities have been enhanced to seemingly superhuman levels. Capable of overhead lifting at least a ton and moving at speeds impossible to any human athlete with superhuman coordination, Protocide is one of the Super-Soldier Serum’s most dangerous recipients.

7 Mockingbird/Barbara “Bobbi” Morse

Created by Len Wein & Neal Adams

Mockingbird with a sword and glasses in Marvel Comics

A formidable crimefighter long before she ever became a genuine super soldier, the SHIELD agent known as Mockingbird ingested a combination of the Super-Soldier Serum and the equally powerful Infinity Formula in order to save her life after a brutal injury. This hybrid concoction seemingly enhanced Morse to superhuman levels, allowing her to dent steel with her bare hands.

The exact upper limits of her strength are vague, but considering her similarly enhanced agility, regenerative healing factor, and potential immortality, this compound formula has elevated Mockingbird from an effective but underpowered Avengers staple and SHIELD agent into a legitimate superhuman powerhouse.

6 Warhawk/Mitchell Tanner

Created by Chris Claremont & Pat Broderick

A result of Dr. Noah Burstein’s attempts to recreate the Super-Soldier Serum, the assassin known as Warhawk experienced far different side effects from previous products of the Super-Soldier Serum. His body transformed into an organic steel compound, Tanner’s strength and durability were enhanced to inarguably superhuman levels.

Able to lift around ten tons with a nigh-invulnerable physical composition that can’t be penetrated by anything less than a highly powered laser, Warhawk is an incredibly dangerous example of what a super soldier can become. But he’s far from Burstein’s only successful super soldier replicant, and his successor has him outranked in of raw power.
