Once I read that the strongest thing in the Marvel Universe is the Silver Surfer's skin, followed by the Mjolnir and Adamantium. Is this right? And, if so, what makes them so special?

    The Hulk's purple shorts appear to be made of an indestructible substance capable of withstanding a nuclear blast. They're also infinitely stretchy. – Valorum Apr 29 '15 at 17:55

Proto-Adamantium: The adamantium-vibranium alloy used in Captain America's shield is the strongest human-made material on Earth. It's greatest strength is its nearly immutable nature and resistance to being damaged or changed. The process used to create adamantium requires the material be brought together, shaped and within a fixed amount of time before setting. The process used to create Captain America's shield was similar with the inclusion of vibranium. The process was lost and therefore unable to be repeated.

Enchanted uru is not made or normally found on Earth and is both more resistant to damage than normal uru metal but it is not indestructible. It's durable and can be enchanted to be even more damage-resistant but its primary benefit is the ability to bind amazing enchantments to it.

To be fair to the Olympians, I will also include Adamantine (the material Hercules' mace is made from) to be another mystical metal capable of being enchanted and having its durability enhanced through mystical/scientific forging by Hephaestus, the smith of the Olympian gods.

Galactus created the Silver Surfer, so it's safe to say the Silver Surfer is by far the most resistant to damage, considering his job duties and the potential threats he faced, he needed to be. Since he and Galactus both possess matter transmutation and advanced scientific capacity they can create or alter matter to make the strongest materials in the Universe. Other cosmic beings can likely create similar near-ultimate materials.

In the current iterations of the Marvel Universe, the nature of the most powerful materials would be similar to the nature of the technological capabilities of the species, so more advanced species would likely have better metallurgical technologies. So with that reasoning, I would expect Galactus and the Celestials to have the capacity to create the most powerful materials in the Marvel Universe.

  • So, are these the strongest materials in the whole Marvel Universe? Silver Surfer > Echanted Uru > Proto-Adamantium? – Thecafremo Apr 13 '12 at 19:25

    If Proto-Adamantium is so immutable, how did they make it into a shield? – Ivo Flipse Apr 13 '12 at 20:04

    Likely the same way they made it now. Mixing the components and shaping them before they solidify. The actual method was not known to anyone because the designer of the technology died. The creation of normal Adamantium is the closest approximation to that original design. The process is a secret even to the writers of the Marvel Universe. – Thaddeus Howze Apr 13 '12 at 22:59
  • Adamantine should, in all likelihood, be mentioned when discussing the strongest materials in the Marvel universe. I don't know a ton about it, but Hercules' mace is made of it, and he seemed awfully dismissive of adamantium when compared to his mace's divine adamantine. (It also appeared on a parallel Wolverine's claws in a recent X-Men comic.) – RedArrogantKnight Apr 16 '12 at 14:50
  • Silver Surfer's skin is likely correct. It can survive black holes and being inside the star.

  • 2 vs 3 is somewhat correct:

    In Marvel Ultimate Alliance game Thor states that uru is harder than adamantium.

    BUT... Mjolnir was made from enchanted uru that was stronger than raw material:

    When Odin removed the enchantments from Mjolnir so that Thor could fight the Hulk HTH, Thor feared that the Hulk would be able to destroy the hammer because its enchantments were removed. (JOURNEY INTO MYSTERY #112).

  • Adamantium is NOT the strongest (aside from those 2) - Vibranium/steel alloy that Captain America's shield is made of is stronger. Adamantium was a result of Dr. MacLain trying to replicate the sheid's alloy.


Given all these discussions, Hulk's teeth might be the strongest.

  • Hahaha, I love Marvel Zombies! And yeah, if all the other answers are correct about the Silver Surfer being so tough, this one gets the trophee. To be fair, I think Surfer could have been weakened in that one, or this could be explained as having happened in an alternative universe. But still, have my upvote! – Renan May 23 '16 at 14:27
  1. The Runner skin. He is one of the Elders of the Universe.

  2. The Silver Surfer skin. He is/was one of the heralds of Galactus. The forces binding together the molecules making up the silvery material that comprises the skin of the Surfer are so great that there are few known forces in the Universe great enough to overcome them.

  3. Captain America shield Proto adamantiun is even stronger than true adamantiun. It was created by Dr. Myron MacLain and then combined with vibranium to produce the alloy used in Captain America's shield. The shield is so vastly strong that is is renowned EVERYWHERE.

  4. The Destroyer armor: it is made of an unknown material, even stronger than uru.

  5. Mjölnir (tie) Made with the mystical metal uru, it has been enchanted by Odin with several powers.

  6. Adamantine mace of Hercules (tie) Another mystical metal, it is impervious to almost any damage.

  7. True adamantiun objects This is the strongest man made material, almost impossible to damage. Wolverine claws and Ultron body are made of this.

Okay I would like to put it like this, you can disagree with me if you like but anyways...

Strongest metalic substance in the Marvel Universe is the Silver Surfer, he is simply too OP to dispute this.

Uru/adamantine are a tie for me, thor hammer vs hercules mace is a tie with enchantments of asgard and olympus also way stronger than anything on earth.

Adamantium/vibrarium are neck and neck, both unique functions and I compare the 2 like this, a heavy tool steel like t10 or t8 vs. Titanium. My logic being for adamantium as a weapon or exo skeleton adamantium is the better metal simply because of its abillity to flex like an excellent katana, and yes edge retention of wolverines claws would also justify this. Vibrarium is stronger but more brittle, it holds its shape no matter what untill the critical stress point is reached making it far better for an armour or a shield.

Dargonite is capable of penetrating Adamantium so I would think that it must be a strong alloy as well. To my knowledge, Dargonite only exists in the alternative future timeline of the Guardians of the Galaxy.

  • 1
    Can you provide any proofs, or tell where was it mentioned? – Schullz May 23 '16 at 13:27

There is this one metal called Dargonite, named after Ktor Dargon. This metal was able to pierce Captain America's shield effortlessly.


It's obvious that captain America's shield contains the strongest metal in comic book history. It's made of vibranium, proto-adamantium, and uru ,the metal used in Thor's hammer. Its original proto-adamantium vibranium alloy is completely indestructible under normal circumstances. The proto-adamantium vibranium alloy can be broken with molecular and reality manipulation, but with the Uru metal, it is stronger than ever and it can be enchanted to be even more indestructible.

    Why is this obvious? – amflare May 4 '18 at 16:23
  • Because the original proto-adamantium vibranium alloy shield can withstand almost anything the 616 earth can throw at it and it has be broken 6 times in the entire history of marvel comics and when it was last broken, it was fixed by mixing Uru metal making it stronger than ever. The Uru metal can also be enchanted to make the shield even more indestructible than it was. – Hunter Strickland May 10 '18 at 19:32

    Then say that, because it is not actually obvious. – amflare May 10 '18 at 19:58

Proto-Adamantium: Captain America's shield is composed of a unique Vibranium, Steel alloy, and an unknown third component. It is virtually indestructible.

  • But what's the strongest material in the Marvel U? Is it Proto-Adamantium? Do you have any evidence to suggest that? – Edlothiad Jul 3 '18 at 13:12

Cap has had more than one shield. He has had steel, vibranium,vibranium/adamantium alloy, and finally enchanted uru. The latter being the strongest to date. Really, it's all just semantics and plot devices though. The rules are always changing. The quixotic nature of enchanted uru and its symbiotic relationship with its wielder makes a broad answer to this impossible. Which is as designed. It's always fun to discover a stronger object or character. Also wanted to add that at one point the Hulk bit off silvers surfers' head. Alternate universe though. Don't get me started on alternate universes.
