On Earth-2149 - the Zombie universe - Colonel America's shield is made of a Vibranium-Steel alloy instead of pure Vibranium. Also, in that universe, Squirrel Girl's squirrels are as undead as everything else. This means that they feel no pain, and will not stop gnawing/clawing at something even after their teeth/claws physically rip out or break off.

So... could Zombie Squirrel Girl make her zombie squirrels damage Colonel America's shield?

    Just because you won't stop doesn't mean you'll succeed. I can punch a tank until my arm falls off, but it won't destroy the tank.

    Then again, it's Squirrel Girl, so obviously the answer is yes.

    Two downvotes. Some people have no appreciation for a good, albeit silly, question.

Short Answer: No

In the Mohs scale of mineral hardness, teeth have a hardness of 5, where as steel has a hardness between 4 to 4.5. So the teeth are slightly harder.

If the shield were made only of steel, the zombie squirrels could scratch it. Given enough scratches (like, a bajillion), they should be able to eventually bore a hole through it.

I think it is fair to assume that vibranium is at least as hard as titanium. With a hardness of 6, titanium is safe from zombie squirrels.

Since his shield has the ultra resilient vibranium in it; it is unlikely the zombie squirrels can scratch it. Their teeth, bones, and everything else would wear away long before the shield showed even a scratch.

On the other hand. You have to consider that Squirrel Girl took out Thanos.

And Thanos shattered Captain America's shield.

So what we have here is a classic paper/rock/scissors scenario.

Squirrel Girl beats Thanos, Thanos beats Captain America's shield, Captain America beats Squirrel Girl.


I'm going to go with absolutely no. It's been established that Captain America's shield is in fact made of an alloy of Steel and Vibranium in other universes as well, including the main continuity universe where is has been proven to be utterly impenetrable to all but the most alpha of mutant/godly powers.

Although Squirrel Girl's little evil buddies may have near-infinite patience, it's unlikely they can make a dent in a shield that has utterly shrugged off (without a scratch) impacts from Mjolnir, punches from the Hulk and about a gazillion bullet-strikes.

    @maguirenumber6 - Dunno. Probably worthy of its own question.

  • Better yet... how do they attach the handle and/or straps to the inside of the shield? You can't exactly use screws or rivets...

  • @Omegacron - I see no good reason they couldn't use glue, suction or powerful magnets. You might as well ask how they make Teflon stick to non-stick pans when it should all just fall out.

  • Teflon... pans... time for a new question on the chemistry SE.

Well pure Vibranium can pierce the diamond skin of Emma Frost. Since the shield is a vibranium alloy, it'll shatter Squirrel Girl's teeth.
