Captain America’s First 10 Marvel Villains, Ranked By Power

by

Captain America originally appeared in Captain America Comics before joining Marvel. While he debuted with Timely Comics, he didn’t officially join the Marvel universe until the Avengers discovered his frozen body in Avengers #4. Before that, Marvel tested the character with a fake Captain America to gauge reader interest. Once established, Cap joined the Tales of Suspense comic, appearing in shorter stories alongside Iron Man, who was the main feature. It was within Tales of Suspense that Captain America faced his first solo villains.

Here’s a ranking of the first ten villains Captain America faced in his solo comic book adventures – not counting his team-ups with the Avengers – ordered from least to most powerful.

10) Sando & Omar

In Tales of Suspense #64, Captain America and Bucky Barnes travel back in time to look into a famous stage act. The performers, Omar and Sando, seem to predict the future with a crystal ball. However, they soon discover that Sando is the true criminal, manipulating Omar into helping him. It turns out there’s no real magic involved—Sando is using a projector to create the illusions. With the help of Agent 13 (Betsy Ross), Captain America defeats Sando and his Nazi allies, stopping their scheme.

9) Bull

Early in his Marvel Comics career, Captain America often faced enemies who didn’t have superpowers. For example, he once broke up a prison escape, though it wasn’t a fight against individual villains. He also battled a criminal organization led by a mafia boss named Bull in Tales of Suspense #59. Bull believed eliminating Captain America would dismantle the Avengers, but his plan failed. Despite having advanced weapons and an armored henchman, Captain America easily defeated them.

8) Sumo

In issue #61 of Tales of Suspense, Captain America went to Vietnam on a solo mission against the Viet Cong. He wasn’t there to fight, but to negotiate the release of an American helicopter pilot. Captain America discovered the pilot, Jim Baker, was the brother of an old friend who had served with him in World War II. The Viet Cong then sent a massive fighter named Sumo to stop Cap, but despite being equally strong, Sumo couldn’t match Cap’s fighting skills. Captain America defeated Sumo and successfully rescued Jim.

7) THEM

THEM was a terrorist group founded by Baron Strucker as part of Hydra. It oversaw two other Hydra organizations, AIM (Advanced Idea Mechanics) and the Secret Empire, though it wasn’t as significant as AIM. Despite its relatively short run – appearing in only 10 Marvel Comics – THEM was responsible for major events, including developing the Cosmic Cube and resurrecting the Red Skull. Captain America first encountered THEM in Tales of Suspense #75 and faced them in three comics that year, but the group has largely been forgotten over time.

6) Nazis

I’ve always been fascinated by Captain America’s early adventures! It’s amazing to look back at his first comics and see who he battled. While he faced a lot of different enemies, the Nazis were by far his most frequent opponents. He actually fought them in eight separate issues before even reaching a total of ten different villains overall! It totally makes sense, though – he is a World War II hero, and standing against that kind of fascist threat was always central to his story. Sometimes the Red Skull was involved with them, and occasionally groups like AIM and THEM would team up with the Nazis, but often Cap was just taking on wave after wave of Nazi soldiers, both in flashbacks to the war and in modern-day stories where they continued to be a real problem for anyone fighting for freedom.

5) Heinrich Zemo

I’ve always been fascinated by the Zemo family history! People often think of Helmut Zemo as the main Captain America villain, but his father, Heinrich Zemo, was the original! He was a brilliant, but terrifying, scientist – supposedly the greatest of the Third Reich – and he built the very first Masters of Evil. He wasn’t just a Nazi, he was using Hydra to try and make those awful fascist ideas a reality, which meant Captain America had to stop him repeatedly. They actually only had one direct fight early on, in Tales of Suspense #60, but Heinrich didn’t survive for long, sadly passing away in Avengers #15. It’s a really tragic, complex story.

4) Batroc

Most people first encountered Batroc the Leaper in the movie Captain America: The Winter Soldier, but he’s been a Captain America foe in the comics for a long time. He’s known for giving Captain America a particularly tough fight. Batroc first appeared in Tales of Suspense #75, teaming up with the villainous organization THEM to battle Cap. Though he doesn’t have superpowers, Batroc is incredibly athletic—his jumping ability surpasses even Olympic-level athletes. He’s also a highly skilled martial artist, having gone toe-to-toe with heroes like Iron Fist.

3) AIM

Though THEM and Hydra were the initial enemies Captain America faced, AIM first appeared in Tales of Suspense #79 and quickly became his primary adversary by issue #82. Originally operating as a part of THEM, AIM eventually surpassed it in prominence, featuring in over 600 more comic books. Starting from somewhat chaotic beginnings, AIM evolved into a consistently challenging foe for both Captain America and Iron Man, largely thanks to key figures like Scientist Supreme and the infamous MODOK.

2) Super Adaptoid

The Super Adaptoid debuted as a foe of Captain America in Tales of Suspense #82 and quickly became one of the Avengers’ most formidable enemies. Initially created by AIM with unstable molecules and a fragment of the Cosmic Cube, its first attempt at villainy wasn’t particularly impressive – it simply disguised itself as Captain America after incapacitating him with drugs. It was defeated by the Tumbler, and Cap managed to recover and win the fight. However, the Super Adaptoid grew much more powerful over time, gaining the ability to copy the appearance and powers of any hero, making it a dangerous opponent for anyone.

1) Red Skull (Tales of Suspense #66, 67, 68, 74, 79, 80, 81)

Captain America’s biggest enemy has always been the Red Skull. Early in his comic book series, Cap frequently battled the Red Skull, both the original villain from World War II – featured in many retold stories – and a new version appearing in the present day. When the organization known as THEM brought the original Red Skull back to life, he once again became Captain America’s primary foe. The Red Skull appeared in seven issues of Tales of Suspense (#66-81) and consistently gave Cap more trouble than any other villain.
