Captain America is one of Marvel's greatest martial artists. Aside from the increased strength, speed, and agility that comes with the Super-Soldier Serum, Steve Rogers has been trained in almost every form of martial arts under the sun. This makes him a formidable hand-to-hand combatant, and that's before even speaking of the unbreakable Vibranium shield.

However, for all of his strength and skills, there are some foes that even Captain America has yet to conquer. There are enemies either too powerful or too skilled in their own right for Captain America to have definitively beaten. Some of those opponents have even been Captain America's friends.

10 Steve Has Never Gotten Doctor Strange Back For Wiping His Mind

Captain America challenges the Illuminati's plans

When Captain America wanted to stop the Illuminati from taking a dark path to put an end to the Incursion crisis, the rest of the group signaled to Doctor Strange to mindwipe Captain America and knock him out. When Cap later learned of this, he took all of his frustration out on Iron Man because of their bad blood.

Cap has never thought to get Strange back for this, and that's probably to Steve's benefit. Strange is the Sorcerer Supreme, and it's unlikely Cap could win that fight without getting the drop on him.

9 Cap's Battled His Friend, Namor, Several Times But Never Won

Captain America and Namor have been friends since World War II. Both men were members of the superteam known as the Invaders, but Cap's principles and Namor's temperament have brought the two to blows several times.

However, Cap's never been able to close the deal on this one. Namor is just too powerful, and Cap can only keep him occupied for a while so that Namor, hopefully, calms down. The closest Steve ever came to a victory is when he got Namor caught in a gene-altering bomb that briefly turned Namor human.

8 Captain America Couldn't Stand Against Ghost Rider

The Avengers once came to blows with the Champions of Los Angeles, a cooky superteam made up of Hercules, Ghost Rider, Black Widow, Iceman, Darkstar, and the Angel. This fight was prompted by the Spirit of Vengeance overtaking Johnny Blaze and sending him on a rampage.

Cap and fellow Avenger Tigra were caught in this path of destruction and were only able to dodge and avoid the Ghost Rider without ever taking him on directly. Thankfully, Thor and Iron Man arrived to get the Ghost Rider's attention. Even they couldn't stop the Rider, though, and it took Angel calming Johnny down to end the crisis.

7 Cap Couldn't Bring Himself To Take Down The Winter Soldier

Captain America and the Winter Soldier lean into each other, screaming. Cap holds his shield and the Winder Soldier holds a rifle.

When Bucky Barnes first returned as the Winter Soldier, Cap discerned his identity pretty quickly. While Captain America was forced to fight the Winter Soldier a few times, Steve could never bring himself to truly hurt Bucky.

There was never a true victor in these fights. In the end, Cap used a Cosmic Cube to give Bucky his memories back, and this ended their series of battles.

6 Spidey And Cap Have Had A Duel, But Cap Couldn't Close The Deal

Captain America and Spider-Man

During Civil War, Captain America and Spider-Man were initially on opposite sides of the conflict. Spidey even revealed his secret identity at this point to show his support for the Superhuman Registration Act--though this revelation was later undone by Mephisto.

Captain America and Spidey fought one-on-one in the early stages of the Civil War, and, to his credit, Cap came close to winning that fight. However, in the end, Cap was distracted by other things and couldn't close the deal.

5 Cap Has Never Outfought Shang-Chi, The Master Of Kung Fu

Captain America vs Shang Chi in Avengers

It has been revealed in the past that Shang-Chi, the Master of Kung Fu, has given some combat training to Captain America before. However, the two have never had reason to fight until the recent return of the Phoenix Force to Earth. The Phoenix wanted to choose a new champion, and Cap and Shang-Chi were among its nominees.

Cap let Shang Chi pummel him throughout the fight, as Steve believed Shang-Chi to be the best possible choice for such a power. However, in the end, the Phoenix saw through Cap's ruse and gave him the victor in the round--though Shang-Chi was actually winning the fight itself.

4 Captain America Has Fought Black Panther Several Times But Never Won

Captain America and Black Panther are close friends as Avengers, but they've also had several fights over the years for many reasons.

Despite these several combat encounters, only one instance saw a true victor--and it was the Black Panther. While the Superhero Civil War was raging, Black Panther and Cap came to blows, and T'Challa was the clear winner--even saying he'd be willing to kill Cap if necessary.

3 Cap Trained Hawkeye So Well Even He Can't Beat Him Anymore

When Hawkeye first joined the Avengers, he had almost zero fighting skills, and Cap laid him out to show him how much of a problem this was.

Years later, Captain America and Hawkeye came to blows when Steve wanted to test Hawkeye. The fight was long and intense, but Hawkeye was able to incapacitate Steve with a shock arrow.

2 Steve Has Never Been Able To Stop Cyclops Despite Their Bad Blood

Cyclops blasting Captain America

Captain American and Cyclops have had several battles in recent years. Both of their respective teams came to all-out war in Avengers VS X-Men. However, Cap has never actually decisively beaten Cyclops in combat. AVX started with Cyclops blasting Cap away with his optic beams. It ended with the entirety of the Avengers and X-Men having to stop a Phoenix-crazed Scott Summers.

Later, Cyclops and Cap fought again, and Cyclops was able to hold his own and even seemingly put Steve down with a frying pan.

1 Captain America Has Never Had A Decisive Victory Over Iron Man

Captain America vs Iron Man during Civil War

Captain America VS Iron Man is one of the most infamous superhero rivalries in comic books. Steve Rogers and Tony Stark have very different methods and worldviews. Their animosity came to fruition during Civil War and with the return of the Illuminati during Time Runs Out. The two have fought several times in that period.

Despite that, Cap and Iron Man have never had a decisive conclusion to such fights. Cap incapacitated Tony with joy buzzer that shorted out the Iron Man armor during Civil War. They later had a secret summit where the two began physically beating one another (which Cap came close to winning but never sealed the deal on). They beat on each other a few more times during Civil War, and it only ended when Cap surrendered in the face of all the carnage the Superhero Civil War had caused. At the conclusion of Time Runs Out, an aged Captain America put on a suit of power armor and had a brutal fight with Iron Man while the world literally ended around them--ultimately consuming them in fire and destruction.
