The giant alien Celestials created powerful dueling races using humanity's genes, which created powerful heroes with a wide range of abilities known as Eternals that fought against their monstrous counterparts the Deviants as Earth's secret protectors.

Led by Ikaris and his powerful psionic abilities on a team that includes cosmic speedster Makkari and elemental transmuters like Sersi, the Eternals outpower most of Marvel's powerful teams even if they mostly stay hidden away from the usual events.

There have been quite a few different versions of the Defenders over the years, but the most powerful is still one of the original rosters that was assembled by Marvel's Sorcerer Supreme, Doctor Strange in order to protect Earth from cosmic and mystical threats.

He was initially joined by the super-strong Hulk and Namor as well as the cosmically-powered Silver Surfer before characters like Valkyrie and Daimon Hellstrom further enhanced the team. A new version of the Defenders recently appeared led by Doctor Strange and Silver Surfer with Red Harpy and others to carry on the lasting legacy.

While the Fantastic Four aren't the largest team in the Marvel universe, they are one of the most powerful and well-balanced given their unique powersets and lasting relationships with each other as the First Family of Comics. Not only does this make them a well-oiled superhero team, but the individual abilities of each character also make them some of the most powerful heroes.

Reed Richards is nearly indestructible and can invent his way out of any situation, while Sue Storm is the secret powerhouse of the group who can both turn invisible and project powerful force fields. Johnny Storm can reach incredible levels of heat as the Human Torch and Ben Grimm keeps the team together with his big heart and super-strength.

The Ultimates included other powerful heroes like Blue Marvel, Miss America Chavez, Spectrum, and even a cosmically-shifted Galactus who had transformed from World Devourer into Lifebringer.

While there have been evil versions of the Squadron Supreme in the Marvel Universe, they first appeared as heroes from a parallel reality that were eventually stranded on Earth to work alongside and fight against the Avengers at different times during their exile.
